A fantastic sounding PS Audio BHK Signature preamp in black. The factory remote is
included and will also control the PS Audio DSD AC and PS Audio CD spinners. The remote is backlit and can dim the BHK’s display completely.
I purchased my dealers demo earlier this year and works perfectly. It is under one year
I am forced to sell, otherwise it would stay in my system, but with a kid going to college
and car to buy, funds have to come from somewhere.
If you want the pure midrange and high frequency response of a great tube preamp, but
extension on the bottom, this is the preamp for you. In addition, the headphone amp drove my Sennheiser HD650’s beautifully and is the best these cans have ever sounded.
The BHK is a fully balanced input to output and this is a big deal and a more expensive way to make a preamp. It has exceptional drive and even reasonable priced XLR cables work wonderfully. It will drive any amp through both its outputs, at the same time.
I am including the factory Psvane 12AU7 tubes that have less than an hour on them. They
are currently installed in the amp and I am including one set of silicon tube rings, which are pictured. I am also including one pair of Tungsram 12AU7’s, which measure strong and were matched on a calibrated Hickock TV7. For 6 volt tubes, I am including one pair of Tungsram PCC88’s from TubeWorld and one NOS pair of Torvac PCC88’s, which were made by Mullard in the UK and were used just long enough to make sure they work and are quiet in the preamp. The preamp sounds great with all of the included tubes, with the either of PCC88’s probably my favorite, although the Tungsram 12AU7’s also sound wonderful.

User accessible switch allows both 12 volt and 6 volt tubes to be used
Differentially coupled balanced MOSFET output stage
All through hole construction (no surface mount parts)
PRP resistors in signal path
5 RCA Single ended inputs
5 XLR balanced inputs
One single ended and one balanced outputs, that can be used together, or separately
High current oversized power transformer
Fully regulated power supplies using BHK designed MOSFET discrete voltage regulators
Full BHK designed zero feedback, discrete MOSFET headphone stage
Front panel standby button for vacuum tube stage
-3dB greater than 200kHz
Volume and balance through a revolutionary new combination of gain and attenuation
Two output DC control triggers
Easy access to tubes and jumpers, if you want to roll with different ones
Each input can be configured as a HT bypass.
If you aren’t familiar with the BHK, the volume control is unique and it is normal to hear
some noise when changing volume. Otherwise, the preamp is very quiet. The top, gloss black surface has small, hair sized scratches from dusting that I cannot capture in photographs. I guess I’ll conservatively rate it as an 8, just for this.
