BOYUURANGE MT-34 MKII

I have owned this amp for three years (in May 2024). The sound quality great I decided about 5 years ago to get back into vinyl records.I up graded my turntable to analog, and only run the vinyl through my old Fisher tower (4" tall) (duel 10" woofers, single 6" mid, single 3" tweeter) speakers from the mid 80's.Some will say these are terrible speakers, but every individual has their own listening preferences. Todays smaller speakers are too harsh for me, and I tire of the sound easily. My Fisher speakers I can listen to for days on end, and because of this amplifier, I close my eyes, and just get lost in the artist and music. And if we are truthful, isn't that what it is all about?The sounds blends in so well that you hear the music, not the speakers. Live albums you can hear the fingers moving across the frets of the guitar neck, and the faint inhale before the next line is sung... Listening to Coltrane, Davis, or Patterson give new life to old recordings. I get lost in the music no matter who the artist is. It is a moving experience.I have not had any issues with the amp or the tubes. It took around 100 hours for the tubes to really break-in, and I now have close to 500 hours on the amp, and the sound quality only gets better with time.I would buy this amp again without question.

I was on the fence with this one. Could it power my speakers, none of which are more than 87db efficient. I am pleased to say it does just that. In 15 watt Triode mode I have no problem driving my Wharfdale Diamond 225. I also have no problem driving Elac debut 2.0 6.2 I have.As far as sound goes, WOW! This amp has such a holographic sound stage its hard to believe. The bass is tight and controlled the mids are perfect and the highs are crystal clear. That is both speakers being tested.What I did not like was ultra linear mode. Though providing an extra 10 watts it was lacking in soundstage.I'm very pleased to have bought this amp.

The Good-First, the sheer weight of this thing is impressive. There seems to be no cost cutting on the materials used, because it is heavy duty. Second, it is actually quite handsome, even to the point where my wife thought it looked nice (which never happens on audio gear). A cage is included and it looks great, as well.Assembly was simply a matter of placing the tubes. All tubes were labeled by hand so it was easy to know where everything went. I hooked my Bowers & Wilkins 606 bookshelfs up started the tube run-in process. I had probably 10 hours on them, before really auditioning them, and the tubes really do need time to fully bloom their sound. The sound is incredible for this price point. The EL34's are about as legit as a tube as it comes, as this is what so many guitarists use in their maps- and I love that. had I kept this amp, I am sure the sound would have gotten even better over the next 20 hours-50 hours. Triode mode sounds really nice, but it does cut doen the power output, so it is a little better for lower volume levels.The not so good-You need efficient speakers for this amp. My Bowers sounded good, but as I turned up the volume I could hear where it just didn't have enough juice for my less efficient speakers. If your speakers have a 90+ sensitivity, this would be fantastic.Next, microphonics in the tubes is a bit of an issue as it adds some noise to the sound, most noticeable in the upper midrange on upbeat rock songs. HOWEVER, I did have my speakers on the chest of drawers with this amp. So, I am sure some some vibration isolator pads on the speakers, and perhaps this amp, would have gone a long way to fix it. If that doesn't eliminate it, then you may want to roll some other tubes in that might fit tighter and/or have thicker glass.Conclusion-I was impressed enough to purchase the next step up from this (https://www.amazon.com/gp/product/B07L6DDYPP/, on order), because I believe it will power my speakers sufficiently. I already bought some cheap isolation feet for my speakers to combat the microphonic noise https://www.amazon.com/gp/product/B075KK8WXM/. IF I still have noise, I will buy some Gold Lion Pre-amp tubes, and I think that will eliminate it entirely (plus Gold Lions are just fantastic).
