PS Audio BHK Signature 250 Amplifier (current model, silver)



Why selling: I'm selling my entire system. There's nothing wrong with it; in fact it's outstanding. It's just *way* too much equipment for my listening area, which is my bedroom. I got carried away and bought what I wanted, rather than what I realistically had space for. My speakers weigh 165 lbs subwoofers partially block my closet doors...etc. (I'm happy to share pictures if you want to see this.) I'm going to downsize to a much smaller system, or perhaps headphones.

This amplifier has rarely been used. It has probably been broken in…that’s about it. It's got one of those very polished, black reflective top surfaces, and I rate it 9/10 because it has some of those faint “scratches” that inevitably appear on that type of reflective surface once you take the plastic off (they’re not even really scratches, more like…thin, faint marks?) I’m the original owner, and after being installed the amp has been in one place, in a climate-controlled, smoke free home with no pets and no kids.

I've sold two products on Audiogon, and have positive feedback for both. On eBay I have 100% positive feedback from 58 buyers and sellers over a period of almost two decades (username: cgwells). I’m an experienced online buyer and seller, and I pride myself on good communication and transactions that benefit both parties. For serious potential buyers, I’ll do whatever you need to be reassured of the quality of the component you’ll be getting. I encourage phone calls (if desired) and will provide additional photos on request.

The new price is $7500. I bought this amp <1.5 years ago (new, from an authorized dealer) and have hardly used it. So basically, you can get a product that’s virtually identical to what you’d get from Music Direct, except for $2500 less. I have the original box and manual.

If you are reading this listing, you probably know that the BHK 250 stereo amp (as well as the 300 mono) is one of the most universally positively reviewed components of the last ten years. These amps have gotten rave reviews from numerous print and online magazines, with multiple reviewers buying the review model and/or making it their new reference amp.

“…Simply put the BHK 250 rocks and does so with a nimble presence that puts the music in the room with you. Neither forward nor recessed, the presentation is, for me, spot on….I can't recommend the BHK 250 enough.” — Dave Clark, Positive Feedback (bought the review sample)

"Bascom’s last collaboration was the creation of the extraordinary Constellation Audio Hercules amp, which costs more than ten times as much in its current version II guise! This more price aware approach was one of the design goals for the new PS Audio BHK lineup: to offer true world-class performance at a significant discount to the prodigious prices found in ultra high-end audio today….Bascom, Paul, and Arnie’s combined 150 years of audio excellence has led to a design of classic physical beauty and sonic excellence that easily achieves the goal of competing with über-level amplifiers, but at a fraction of the retail price. As audiophiles, we sometimes fall into the ‘price equals performance’ trap. We fear being the emperor with no clothes when our friends ask how much we paid and it was, gasp! LESS than what flagship gear is supposed to cost. Naturally it must not be that good. This amp is that rare Holy Grail whose sensible price belies its astounding performance. Hand built in America, it may well be your final amplifier purchase.” — Eric Neff, HiFi+ May 2017
