PS1 is OK for what you pay for it. It's no TOTL CD player, that's for sure. I have one and I use it as a "secondary" player. It "will" smooth out your high end--but many feel it does that because it rolls off both the "highs" (so there is LESS detail there!), and the "lows" (so don't expect nice tight, deep, well articulated bass).
This player is best suited for general background listening and is "most" definitely not my player of choice. Both the HK and the Joida below are far better players when it comes to representing the full sound spectrum. The HK can get a little harsh if the recording is problematic, but the Jolida tends to roll with whatever you put into it. Then again, that new Jolida is TOTL for them and has four tubes in it!
I do use my PS1 in my home office while I'm working and it does an adequate job there. I'm still trying to figure out "exactly" what the Stereophile reviewer was "hearing". lol (And yes I have the original 1001 with the RCA L/R analog outputs).
As mentioned above there are quite a few threads about this on AK and the PS1 has no shortage of fans here. My own views are, of course subjective, and may go against the grain. But that's what I hear.
