PS Audio BHK Signature 300 Monoblock Amplifier

 

Yes, the BHK preamp and amps are that good. But before you pull the trigger you need to know this. When Bascom King was designing the BHK amps and preamp, he turned to Upscale Audio to try different tube types and get the voicing just where he wanted it. Of course using vintage new old stock (NOS) tubes could not be used for production, but we have an intimate knowledge and understanding of how to take an already incredible product even better. And not by a small margin.

Upscale Audio is not just a large dealer, but the importer and distributor for PrimaLuna and Kiseki. Our buying power means that we will give you the best price, period. There is no such thing as some deal so special that you don't call us first. Do not make a move until you call Uncle Kevvy. If you have a trade in, we need it and will give you top dollar!!

We found a very special tube made by Tungsram that Bascom King likes a lot. He should. They add a level of texture and sense of space that is incredible. BUT recently I found a small stash of them that are unique. They had been locked up in a warehouse in Serbia for over 50 years. We graded out them by only considering the ones that have the highest transconductance for longest life. Then we look at the measurements and accepted only the ones with a triode balance of 5% or better. We then tested them again, this time for gain, so the two halves of the tube amplify equally and required the same 5% balance. If they pass that test, we put them in a moving coil phono stage with 60dB of gain and listen to them with headphones, carefully listening for both noise and microphony, to achieve the absolute blackest background.

This tube we are calling the Tungsram BHK Select, and is not available to the public. We have a total of 100 of them. We can offer you the regular Tungsram, but not these.

Every BHK power amp and preamp purchased from Upscale Audio will come with TWO SETS of Tungsram BHK Select Free in addition to the stock tubes, so you will get a product with a HUGE increase in performance for many many years. Call Upscale Audio today and ask for Kevin.

Okay kids….here’s the word. I am a tube snob; and you know it. I think that really to get tube sound you need a tube amp. And there are ways to achieve that with no muss and fuss if you want advice on it. Call Uncle Kevvy for the lowdown on that. But if you can’t go all tube for some reason and you want to go hybrid…well none of them really spin my propeller. Except this one. Out of the box it is incredible. But you need to know that the designer Bascom King was in touch with me and we wanted to see how far the performance of this amp could be pushed. While all this fun was going on, Infinity loudspeaker founder Arnie Nudell got involved and lent an ear too.

The tube that they love most is a specific Tungsram. A vintage tube older than most of my customers. What it does is give you even more of the 3D effect that tubes are famous for, pushing this amp to be as close as it can be to being what we all crave. A pure tube sound.

So this is what we have decided to do. We’re not selling any more of these Tungsrams (Well..truth be told we let Bascom buy one more set). Instead we are going to give each customer who buys their BHK amplifier from Upscale Audio TWO sets of Platinum graded tubes, our very best, no charge. With two sets you will be rockin’ for 10 years before you even think of re-tubing, and we will always have replacements because they are no longer for sale to others. And we guarantee the best price to boot. Period. So you buy from a source you can trust instead of some jive-ass guy that’s never touched a tube. Call Uncle Kevvy at 909-931-9686 and he’ll get you the hook up.

The BHK Signature 250 and 300 power amplifiers are the culmination of one man’s half-century search for perfection in music’s reproduction. Bascom H. King has designed amplifiers for many companies, some selling in excess of $100,000, including: Constellation Audio, Marantz, Infinity, and Conrad Johnson. This is the first amplifier Bascom felt was good enough to lend his name to. It is his finest achievement in a lifetime of work.

Available in both stereo and mono models, the BHK Signature series is unparalleled in its ability to render details formerly lost in the music. The BHK Signature is a hybrid design enjoying performance benefits from multiple design techniques including, a balanced differential vacuum tube input, balanced differential MOSFET power outputs, and separate, isolated, analog power supplies feeding each.

When it comes to musically controlling and powering loudspeakers, the BHK Signature has no peer. The stereo Signature 250 produces 250 watts/per channel into an eight-Ohm loudspeaker, 500 watts/channel into four-Ohms, and stable into 2-Ohms; enough power to satisfy even the hungriest of loads.
