A lot of hype about PS Audio, deservedly so ?

PS Audio's quality is top notch.  Built solid ....  Some other brands will seem a bit chinzy when compared side by side.  Sound is solid as well. 

My Stellar Gain Cell DAC and factory refurbished Perfect Wave Memory Player just arrived today and the sound right out of the box is already noticeably more natural and vivid than my previous source, an Audiolab 8300CD. 
By the way, newer Audiolab gear, I've learned the hard way, is to be avoided at all costs.  Nothing but trouble even if it does sound superb.

NO HYPE, JUST QUALITY...

A big, big PS Audio fan. Been buying from them since the late 90's and have owned various power cords, power ports, soloists, power conditioning (P300/P600/P5), power bases & a DS Jr.  The free upgrades, trade in policies, customer engagement and service are top notch. I have routinely talked to the owner PM directly when needed.

I am moving away form their power conditioning though and have removed from my 2 channel audio system (at a suggestion from John R at Audio Connection). First with a Wiremold strip and now with an AQ Niagra 1000.  For an almost 20 year user of this technology it was fairly revelatory for me (improved flow, dynamics, liveness, etc).  AQ is making a very nice product as an alternative to power conditioning.

That said I still heartily recommend this company

I own the BHK-250 Amp and Pre Amp. 100 % satisfied.  PS Audio customer service is excellent... 0 complaints. Anyone in the market for a amp or pre amp, please give PS Audio a look as part of your research.
