Is no preamp really better that a good preamp?


Hi All, I have PS Audio gear, and both my DAC and my phono section have enough gain to run directly to the amp. Is this really the optimal arrangement, or might I actually get better sound by adding a good preamp, say a Cary or a Modwright tube unit, to the mix. Thanks in advance.

Well, so far 2 of the predictable sellers have arrived.
Peter should shamelessly be along soon............
The 2 "sellers" are offering opinions and they are different but valid. Where's the shame?
I wish it were George. The interaction will be with only an un-buffered passive pre's volume control, then. Does that include those with optical attenuators (Lightspeed)?

Umm, maybe using the forums for financial gain?
This is getting beyond me, but I appreciate all the input. To summarize: I power Martin Logan Spires with a Spectron Musician III Mk 2. I also use PS Audio DirectStream and their Phono section. I would actually love suggestions as to what preamp under $5K would be a strong match. I listen to all kinds of music, and I love clarity, especially in the mid and upper ranges, more than all other acoustic qualities.
I should mention that I loved my Cary sli-80 integrated amp, so I wonder if a Cary Slp-03 or Slp-98L would be good choices for me. I'm coming off several surgeries and don't live close to any dealers with top rate gear, so getting out for many auditions is tough for me.
