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
gamechanger. Going DHT for preamp is like moving from ss to tubes. Like
going from monkey coffins to open baffle. Like, vanilla to chocolate.
This one has every upgrade imaginable. Comes with the Beequiet attenuator
upgrade (a $269 option) as well as big upgraded Obbligato Premium Gold caps
inside as well as Nichicons and the best Dale Vishay resistors. Also
inside, the base was fortified with strong L-brackets and inside walls
are lined with dynamat sound-damping material which helps cut down on
microphonics a good bit. Just installed new pair of EH 300bs. 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...
Only selling because I upgraded to a 5-figure DHT preamp with remote (a must for me, don't judge!).
Here is a link to more info about this piece:
The base price for upgraded kit is $1644, another $1050 for assembly (which
Bottlehead actually no longer offers I believe), over $300 for tubes,
caps, and other tweaks for a total of around $3000+.
These rarely come up for sale and are no longer available pre-built. Here's
your chance to get one already built with every upgrade possible.
I will cover domestic insured ground and 3% PP fee. International buyers
please inquire about extra postage to your country and please note that
it is 120V and not easily changeable.
I will also throw in a nice brand new thick (14AWG) 6 foot PC.
I always overpack and guarantee it to arrive in perfect working order.
Feel free to ask any questions and I'll do my best...
