I’m using this tube buffer between my Yaqin MC-13S and my thirty year old Rotel RCD-855 CD player. An immediate improvement…sweeter across the whole audio spectrum right out of the box…I can’t wait to hear how it sounds when the tubes break in!

Great experience buying from China-HiFi. The Amp sounds great, and is geting more of the Low Frequencies cutting through the Mix as I use it. Overall clearer tones so maybe not more Bass, just clearer all-around sound. It was packaged very well, and came to me in perfect shape. Easy to Set-Up too. I would’ve paid the extra to have it shipped faster, though it was worth the wait. Customer service was spectacular, with communication, and adivce. Would not hesitate to buy more products in future. Im from Hamilton, Ontario, Canada so it took awhile, just over 3 months to get here. With everything going on in the World, and here in Canada, hence pay for faster shipping if you want/can. Great sound, better than my Old Faithful 1980 Marantz, both Using my Sansui SP-55a’s. Just has that much more separation, dynamics, Clarity is the biggest difference. Thanks China-HiFi.

ON PAR WITH SOME HI-FI PRE-AMP WORTH 4000.00 CANADIAN AND BETTER THAN MOST

I bought the X7 months ago along with a Xiansheng DAC and they sound fantastic together playing through my open baffle speakers. It's way more power than I need for my ~98db sensitive speakers but the bass is strong and fast, mid-range is very full and textured, and highs are more than sufficient (I get very mild roll-off above 15k due to my coax full-range drivers) - not crunchy, brittle or overly bright. I had an issue with the remote-control PCB which caused the amp to randomly mute or change volume. I emailed Mr. Lee and he sent out a replacement board right away which I installed myself (2 screws and some clip-in cable connections). Flawless again! Fantastic service. Also, while I had it open I saw the very high quality engineering inside. This is a well built, quality product equal to just about any mainstream brand. I'm very happy with this purchase and with China-hifi-Audio.

Well, what to say...I got the amp. very fast, everything is working well. I bought two pair of loudspeakers. One pair are the Numan 1987 retrospective MkII wit 4 ohm and 85db sensitivity and the second pair are the Dali Oberon 5 with 6 ohms and 88db sens. The A10 plays the Numan easier and it sounds louder than with the Dali. I changed the output from 4 to 8 ohm and the Dali sounds now much better than on 4 ohms. But in the end the Numan will win...... I would buy again, but its not a bead idea to spend more money and order a more powerful tube amp.

Shipping was about 2 weeks to Canada. UPS delivered to the garage, driver said it was too heavy to bring into the house. Lucky i own a dolly as the box is big and heavy. Unpacking, the product was very well packaged and protected. One problem is the unit is so heavy you need two people to lift out of the box. Although the box was banged up the unit arrived in perfect condition. Nice looking unit especially with the blue VU meters illuminated. I am letting the stock tubes burn in. The 845 tubes are impressive looking giving off a lot of heat. Remote basic but a solid, made of aluminium not plastic. Sound: It seems to becoming a little softer day by day, great separation. Listening only to vinyl (note there is no built in phono preamp). A little too much bottom end bass but it may be the placement of my speakers (Klipsch Forte III). With efficient speakers the 800i has plenty of power (can't go beyond 15% on the volume). Have ordered some tubes so will try upgraded 845 to start. So far very pleased. One minor criticism, the mode select is a small rotary knob listed "A", "B" "C" & "D". I can never remember if phono is "A" or "B"....

Что может быть лучше чем получить r8 посылкой к новому году. Оплата переводом через банк. Конечно волнение за оплату, но усилок блогодоря сдэку у меня дома. Не боитесь переводов ( на тот момент были проблемы с пай пал). Доплат больше не было. R8 хорош, абсолютно тихий- только музыка поет. Спасибо магазину, всегда был на связи. Всем всего наилучшего.

Ottimo prodotto bello da vedere e sentire ottimo prezzo

Very good amplifier, build with care and good components. The sound is awesome !!! a little bit more of updates should be welcome, without this is a 5 stars.

First of all thank you China HiFi and Yong Lee for the speedy response to my emails. This amplifier is fantastically good just out of the box. Had always wanted a 300b SET amplifier to try out after constant recommendation to me from my audiophile friends but could not afford one due to the cost until I chance upon the review of this amplifier on YouTube that made me plunge into it. Having heard from friends 300b, this amplifier is a run for the money. Sound is clear and transparent with pretty good holographic vocal presentation. Notes from strings and piano decay really well and there is really good lower frequency response, not too light nor too heavy, just the right amount. Cannot wait to let it run in further with perhaps even better sound. Do not ever be put off by the small output wattage. With good design and parts pairing up for the amplifier it can give you an exceptional performance.
