How reliable is PS audio equipment?

I have a PS Audio Stellar Gold Preamp, a pair of M700 Monoblock amps, and a Directstream DAC Mk1 (modified by APS Transformers.) In the past I have had a Directstream DAC Junior, and a Stellar DAC. I had one issue with the Stellar DAC (failed right channel); even though it was out of warranty, PS Audio fixed it for free. The Stellar Gold Preamp had one problem when brand new (triggers didn't work), but in all fairness, I was a beta tester on that unit, so some issues were expected. All in all, I have had PS Audio components of various models for about 10 years, and found them to be very reliable. On the rare occasions that a problem did ensue, they were very responsive and great about solving the issue with fast turn around times. I would certainly not hesitate to purchase their products.

The Directstream DAC's are built to last.  We upgrade them currently and are hard to beat at any price. They simply sound awesome with the upgraded nickel transformers and power supply.

I have lots of PS gear now, and have had various PS gear for 35 years...never a single problem...and if I have questions it's always very easy to actually talk to someone...

I did have problems with the "card" that accepted the internet input on my DirectStream Mark 1 DAC.  It gave me fits. I complained to them (politely) and was given a retail trade-and a discount on a new DirectStream II and and AirLens.  Not only have they been a trouble free performer, the output quality is really excellent. They punch WAY above their price point IMO.  Someday I'll swing for the fences and get a WADAX or maybe a Playback Designs unit but for now and for the foreseeable future I'm thrilled with my PS Audio DAC and streamer.

If you want less distortion and a more realistic sound experience replace them cheap Edcor XS4400 audio transformers with custom nickel transformers and replace the cheap IEC AC inlet.  Major improvement in sound quality.
