Ted: kudos to you and the design team, coming from analogue and dabbing around with digital for a few years, a.o. having (had) a Lampi L4, means that I indeed appreciate the PSA DS, esp. with the current Yale SW that I got and is currently being burnt in.
The hint with the tube buffer is, as you know, to yield a more euphonic result. Though I have an all tube system, I think others may benefit in a possible future tub insert.
I started this thread NOT to utter my critique but hoping to gain MORE OUT the DS.
As for those few replies with a somewhat defensive attitude:
-First of all, forums are intended to exchange ideas and the manufacturer may benefit from a closer relationship with their customers.
- Secondly, I am no spring chicken, having modded most of my gear for a simple reason: affordability and the law of diminishing returns. PSA to my understanding has designed, manufactured and marketed to a broad segment. If PSA would make a super-duper DAC with high end components (again, I am not criticizing the DS) it would retail north of $10k, not their target audience.
A good example what I mean is the Oppo BDP-105, already an excellent blu ray player, mods by Dan and Ric (Modwright, Tweakaudio) takes the 105 to a higher level, indeed at a cost. Great designs in the commodity space like the Logitech Squeezebox are the foundations of other great things like the Lampi.
I agree that most consumers will just deploy the gear out of the box, some upgrade the obvious (power cords, fuse, footers, etc), few grab their soldering iron in the hope of reaching higher level.
Some designers (again, PSA folks not targetted) did not even know e.g. that caps are directional, some speaker manufacturers in the past have claimed that (speaker) cables can not make any difference. Still at least one DAC manufacturer (again, not PSA) claims that none of the USB cables can make a difference. Who is right? The more adventurous owner, seeking the “more” of his cherished unit, may benefit.
pmotz, thanks for the info!
P.S. Elk, what gives you the assumption that I am monkeying around? Even if you have an electrical degree, it is not appropriate to welcome a fellow IEEE engineer which I am. This thread was not started to solicit users to swap out ad hoc components. It is NOT about the a different value but a higher QUALITY of the component. If you have ever upgraded simple components to start with, like IEC and plugs with higher end components, maybe an isolation trafo, you would have known better than to put on your condescending hat.
