My PS Audio Stellar Gain Cell is surplus now that I've moved to a Townsend Allegri Pre-amp.
It is a really nice solid Pre-amp and DAC. It replaced a Bryston BDA-1 and Schitt Saga pre-amp combo and to my ears sounded better than the DAC and was more convenient to use than the Schitt with no loss of sound quality.
As you'd expect from PS Audio, it's a really solid well built unit. I bought it new from David at MCRU a couple of years ago.
I think the conclusion from this review sums it up well:
Comes with remote and original packaging.There’s no way around it, this is one hell of a lot of value packed into a single chassis. And the sound is as good or better than you are going to get for the price–especially when you consider the Stellar is both a DAC and a preamp. It provides outstanding, modern digital conversion as well as clean analog source selection and volume control. And it does so without adding noticeable noise or veiling, and without removing detail, depth, or tone color. Aside from a couple usability quirks, its operation was flawless, and the build quality is exceptional. Highly recommended!
I'd like £850 plus postage (or collect from South Worcestershire)
