This superlative preamp sounds as you would imagine. The sound is HUGE
and uber transparent, it being a single gain stage with no cathode
follower, and no global negative feedback. There are only a few DHT
preamps out there (you can just about count on one hand) and this is one of the few that utilize the 300B. By
far the best bang for the buck AFAIK. This should be the last preamp
for most people. Just so so so much fun to listen to. This pre is for people who like their soundstage BIG and
their images HOLOGRAPHIC. Seriously, you will never go back to hum
drum 12AT7 or tiny 6922 or 6SN7-based preamps after hearing this. It's a
This one has every upgrade imaginable. Comes with the Beequiet attenuator
upgrade (a $245 option) as well as big upgraded Obbligato caps inside. Also inside, the bottom plate and inside walls of base are lined with dynamat sound-damping material which helps cut down on microphonics a good bit. The good-but-not spectacular EH 300bs have been upgraded to Psvane Treasures T-II (which themselves are slight upgrades over the vaunted Black Treasures). These tubes (bought new by me from Grant Fidelity and never used as power output tubes) are the least microphonic that I tried in this preamp and they sound super smooth but with great detail and attack. Sound is absolutely huge. The EL84 input tubes were upgraded to the seldom-seen Russian 6N14N-k which are military/industrial grade tubes that are supposed to last forever (and they sound amazing and are super quiet). I also have rings on all tubes. Oh, and it rests on some nice super cushy rubber feet (can't remember name or exact material but they also help with microphonics a lot). In all, I'd say microphonics are really no longer an issue. I had this unit way out in the room on my coffee table (with long IC's--which it can drive easily btw). In other words, it was in maybe the worst place to have it (ie in front of speakers, good distance from sub) and I had no issues with feedback/microphonics. So unless you hit the tubes themselves you really won't notice any microphony at all. It has been well tamed...
