Divine Delta - AREA DVD (Germany)


September 10 - 2018

"Well done, XTZ The Divine Delta is visually an impressive appearance, the beautiful optics combined with exemplary processing. If you then connect the large bookshelf speaker, you can immerse yourself deeply in any musical world, and no matter what kind of music it is. Either club music, classical music, jazz or pop, does not matter at all: The delta always plays sovereign, always cultivated, extremely pleasant, at the same time dynamic and with extreme SPL capabilities - for the money invested almost unrivaled at present."

Spirit SUB 12 - Hemmabio (Sweden)


August 03 - 2018

"A thoughtful product like this one is fun to review because I can give a wholehearted recommendation, but it's hard for me not to make a brainwashed impression when I'm not expressing any direct criticism. Personally, I like black or slightly snowy dark wood. But anyone who wants to use the subwofer in a home cinema will appreciate the matt black, while the matt white is more suitable for modern living spaces. RCA outputs are no important detail, but it is also missing if we are to dig into any shortcomings. In other words, this subwoofer is good, really really good."

EDGE A2-300 - Audiophile Magazine (Thailand)


July 23 - 2018

"A2-300 has passed my test of power and dynamic when I listen at high volume level with enormous bass music. I continue using high sound level but the chassis is only warm for my touch. This is normal to the ICEpower amp. I found that the frequency response is very stable and precise. It has good sound since the first minute after turn on, no need to wait for ten more minutes like other amps. The reserved power push music with like liked and musicality with truthful presentation. With various kinds of music, vocals, pops, any reordings, it generates sound with openness and no hiding..."This is the dream amplifier which is easy to use and you can live long with it. Anyone who is looking this style of amplifier, this is the golden opportunity for you."

"The M8 Tower and M8 Center, with the eye-catching 6-channel array of tweeters, provide an ideal dispersion with ultra-low distortion. Combined with the S5 dipols and powerful SUB1X12 subwoofer, the XTZ Cinema set is a real eye-catcher for rousing home theater sound at the highest level. "

EDGE A2-300 - Fairaudio.de (Germany)


June 18 - 2018

"Actually, I do not know any power amp - sorry for the somewhat flat-looking, but true statement - that delivers so much for so little money. It is not just the sheer sine wave power of the XTZ Edge A2-300, but the sound as well. On the plus side there is a strong, fast bass range, an astonishingly "analogous", almost tube-like fine midrange resolution, impressive coarse and fine dynamics as well as a stage construction, which is characterized by a clean, accurate presentation and a lively, non-dissecting sound. If you add price, workmanship and practicality (it's not a problem to put it in your laptop bag), you can only congratulate the manufacturer for the XTZ Edge A2-300. "

"Yes, with this concept and the high quality of the material, competitors will have a hard time placing something equivalent on the market at a price of € 3.990, which is certainly due to the advantage of direct sales, less costs and margins due to non-existent retailers. For us the XTZ Divine Delta is certainly the reference in this price range, this time we have found nothing to complain about and deserve her our highest award. "

"XTZ creates the sensation with the EDGE A2-300: a "Masterpiece", our highest and therefore rarely awarded test award, for a two-channel amplifier that costs just EUR 495. High-quality processed, extremely compact, and acoustically simply terrific. That's what winners look like."

"The subwoofer from XTZ costs half as much as the others with the same size and impact. And does not get beat by anyone!

Lightning fast, distinct, and very powerful means that XTZ SUB 1x12 is a top-of-the-line subwoofer for both music and movies. It is also pretty easy to place. And it costs half as much as its competitors!"

February 02 - 2018

"In our test cinema, the XTZ set was able to implement 100 percent of its laboratory-determined advantages and played at a particularly high level. The perfect tonality of the entire set and its balanced dispersion characteristics, which forms the basis for precise spatiality, really appealed to us. Even acoustically very complex scenes from films like "Lone Survivor" or "Edge of Tomorrow" were solved wonderfully by the Cinema-M8-Set and left dialogues crystal clear above everything else without dissecting the whole picture or even destroying it."

"This XTZ combination makes it possible for the owner to put a smile on his face and possibly to re-live existing titles. The Spirit 2 are wonderfully present in the action despite their size, so they control the film action with a very precise and clear voice reproduction but are also able to do very well in the midrange."

December 20 - 2017

"When writing these lines in the conclusion, I notice that in the above description of sound I delivered the greatest compliment for the XTZ basically en passant: All speakers, which came to my mind as a benchmark, are, concerning the price level, at least one level above the Alpha. This clearly reveals the level at which the XTZ Divine Alpha plays: resolution / transparency, dynamics, airiness, long-term fitness and neutrality are on an absolute high-end level, also in the range far above 10.000€ there is not (much) more to get."

November 20 - 2017

"It is difficult to find a subwoofer to fully fill a 200 sqft area with high dynamic low bass at the same price point of SUB 1×12. I am sure that higher price model would have at ease of fulfilling that, but that would be another story to tell. If you are in the market for a natural cinema sounding subwoofer, but also be able to tune for your personal taste/preference in bass, you should definitely give XTZ Cinema SUB 1×12 a try."

99.36 MK3 (FLR) - Technic3D.de (Germany)


November 18 - 2017

"99/100 Points" "Based on a well-tuned, deep and clearly structured bass, the sound of the 99.36 FLR is accentuated by a variety of timbres, a high degree of transparency and detail, as well as a concise and vivid representation of vocals. The testers especially liked the way the Fountek ribbon tweeter played, which doesn't contain any kind of tonal hardship or hissing." "With their sonic abilities, the XTZ 99.36 FLR catapults itself into the high-end league of passive speakers and is now the Technic3D reference in the price group around 1500€ / pair."

"The XTZ Tune 4 is a real "wonder" or realistic, a first-class (active) loudspeaker but also as a stereo solution for the living room. All these possibilities make the Tune 4 more than just a great speaker, whether in the sound itself, or in the quality of the cabinet and its overall features. The speaker provides an amazing dynamic range and amount of details, also the bass qualities are astonishing. If you need more, you can also easily connect a subwoofer to the subwoofer-output." "From our side, there is a clear purchase recommendation."

Tune 4 - Stereopluss (Norway)


July 01 - 2017

"There are not many options for really good sound on the desk. We have already tested the Quadral Rondo Active and they are certainly a good alternative but still I find that the Tune 4 gives a better insight into the music with more timbre and details in the sound. Furthermore the Dirac DSP gives you a unique opportunity to adjust the sound as you like. Whether you're working, surfing or just sitting in front of the screen, the Tune 4 always make an excellent impression. The Speakers can also be used to support the TV sound, for example, via the optical input and it definitely sounds better than any soundbar! "

"The XTZ Spirit Sub 12 is able to convince in every discipline. Stylish optics, high-quality workmanship, rich equipment for great flexibility and a powerful yet precise sound are the characteristics of the Swedish subwoofer. Weaknesses are looked for in vain." "The competitors are also strong, but the XTZ impresses with its high acoustic harmony and the absolutely identical handling of music and movie source material. Very high SPL capabilities and an outstanding precision, even with parallel occuring bass effects, are part of the  impressive performance." "This is how to build active subwoofers: the XTZ Spirit Sub 12 combines enormous performance and high-quality appearance for a small purchase price"

A perfect lacquer finish, high-quality connection panels and many possibilities of sound adjustment are not common in this price class. The subwoofer offers a tremendous performance, the built-in DSP and the sophisticated bass reflex adjustments are a clear statement towards the competitors at a price of just under 550 euros."

I had an old Nad amp that was lacking clarity, also the Quad 12l speakers I had did not have enough bass for the open plan living space. I opted for the A2-300 with the addition of the sub 8.17. All I can say is wow..... THe clarity, soundstage and the bass from the sub is awesome. I thought I may need new speakers, but the Quads sounds amazing with this set-up. I really think both the amp and sub makes my system sounds like true high end system System Quad 12l speakers Pre-amp Bluesound node 2i A2-300 XTC 8.17 sub
I've enjoyed my two XTZ 10.17 edge for now more than a year and have used them for nearly 700 hours already. These subs are fantastic, and nothing short of a bargain at this price. You get clean, articulate yet chest crushing bass from these little monsters. The 10.17 edge will of course be more at ease in small to medium rooms if you like to listen at very loud levels. Fortunately, the 12.17 edge is here if you need even more power (but you could also buy two as I did, for even better results!) The finish on these subs is really good, the matte black is unconspicuous yet classy, and the box is rigid, heavy and sturdy. The multiple ways to tune your sub are also worth exploring to better suit your room and your taste. I also wish to acknowledge the quality of the customer service: responsive, personalized and eager to answer any question you may have or fix any problem (thank you Mario). Great subs, great business!
Produkt: EDGE A2-300
I am very pleased with the amp. i am able to squeeze my 2.1 budget system effortless (Marantz , Micca RB42 ). in the future i will buy another edge and use them both as mono block for an Ohms Walsh speaker set in my new home . they arrived perfectly to Calgary AB. Canada
Produkt: EDGE A2-300
Using the Edge A2-300 alongside several Emotiva PA-1 amps (now discontinued) which use the same ICEpower core. The sound is indistinguishable, which is to say of great clarity and detail. Shipping to the US took under a week, and the unit arrived well boxed.
Hi I have received my XTZ 10.17 Edge subwoofer today. Wow. Beautiful gloss black finish. Sound is awesome. I have heard many subwoofers including Rel and have owned a Bowers and Wilkins asw4000. This thing really is amazing for its size. Bass is super tight on par with the Bowers and Wilkins. Not as loud or quite as deep but it is less than a quarter of the size and looks so much nicer. I have been searching for a good subwoofer that is small enough to fit in my room but doesn't compromise on sound. I have found it. Truly surprised. It's magic. I was a bit worried if had made the right decision to buy something without hearing it for myself and was unsure of whether I should have gone for the 12.17 edge but I'm glad to say I think I'm made the right decision. Thanks

Just took delivery of this amp today and it’s hooked up to Dali Menuets on my desk fed by Tidal streaming through my ipad and Oppo HA2 on lineout. This is a fabulous set up and I’ve already had my first goosebump moment. I was a bit worried about it having too much power but the little attenuation knob on the rear has limited that risk nicely so no problems. I might struggle to get any work done now as everything sounds superb. Fits neatly on the desk and I think the form-factor is terrific. Great job XTZ!
Produkt: SUB 8.17
I’ve bought two 8.17 subwoofers mainly for stereo. They acompany my Kef LS50 W Active speakers. So now I have a complete active full range stereo setup. These little subwoofers are wonderfull.. they are powerfull and go as deep as 29 Hz in my 45 square meters room. I use Roon DSP for room correction (measured with REW) and add a housecurve with the KEF DSP. Crossovers are set internal in the Kef DSP, 80 hz for the Kef and 85 Hz for the 8.17 Now I have a powerfull clean and detailed bass and because the Kefs doesn’t have to play the deepest bass, they sound clean and fast in the midrange and highs. Thank you XTZ for these fantastic little subwoofers. I’ll hope XTZ one day will do active dsp speakers too.. the 99.25 maybe?
Produkt: EDGE A2-300
That small size is no indication of what this power amplifier is capable of. On the cooler side of neutral which is ok by me. That grip on the woofer of my Elacs is unheard of at this price range. Thank you XTZ for making high end sound available for the masses. Great after sales support too from XTZ, and a personal thank you to Tracy Zhang at XTZ HK for her patience and support.
