I have the SGCD since June 2019 with the S300 amp.
Have had problems with both units since date of purchase.
The S300 had a bad 12v trigger and two bad output boards-was on line and voice with PS Audio support and finally they conceded to have the amp sent in for repairs-exhausting. Also, from day one, I realized that the filters F1,F2 and F3 fail to exhibit any audible difference-Also from day one, I have had problems with the display of the correct sample rate-its always 44.1 irrespective of the input rate-and using USB there is no sample rate display.
Numerous calls and notes have passed from me to PS Audio over the year + of ownership. No resolve-I just realized on the Forum that these sample rate display have been an issue for a long time and even in units that were sold in 2020!!!
I have had emails from Paul indicating that this is a software problem and its on the list to be corrected- well if this has been known to be a problem why are the SGCD being sold with the problem??? Again, it was noted in 2019 and in 2020 for current new owners!
Does PS Audio care???
Its intuitively obvious that continuous sales without correction of problems prevails.
This is sad-
I find it annoying to see the daily podcasts from PS Audio revealing a “home town-folksie” attitude with poor QC and service of known problems being ignored.
In addition, since there are no local dealers to go to handle problems and the 1000 + mile barrier between this consumer and the supplier further insulates and delays resolve. As you know, email and IM, communication is , at best, ineffective and mostly ignored.
BTW have you read the manual for the pre-map? Aside from spelling errors, incomplete explanations of the functions dominate.
I’m done with this company. However, it is not a comfortable position to “write off” the problem and swallow the cost for a product with problems known to the manufacturer!
