Review on BOYUURANGE Reisong A12: Superior EL34 12AX7 Hi-Fi Tube Amp for Audiophiles by Daniel Roe

Good buy! Unbalanced flea amps require very careful matching with speakers in order to shine. Very high sensitivity and minimal impedance drops are required. Single driver full range speakers are ideal. Tried 600rpm. Not bad but I'm guessing the sensitivity rating. My similarly rated 8 inch full range horn speakers played much louder at a given volume setting and sounded much better too. Got the 600s back and stuck with my 8" full range. If you have DIY skills there are plenty of plans for cheap DIY full range speakers. Surprised that there are no more listings for Revain from this seller. I would also like to add "that speaker placement and toe-in are crucial for full range speakers. Complete silence. No noise. Just beautiful music! With the system, I was aiming for the greatest possible purity. All analog, no EQ, no subwoofer. That sounded good. However, if you... hook up a REL T7 subwoofer (don't try to use another subwoofer with this system...most subwoofers won't connect to this amp and this is an amazingly musical subwoofer, despite some naysayers. Trust me!) along with a soft top cut mids around 2800Hz by Roon equalization Absolute luck!The best of all worlds.It was stupid to limit yourself en! I haven't turned on my Mark Levinson transmission since then!
