I decided to search google for the KSA 50S and your completed auction from Audiogon came up showing you got the piece for $1020. Nice buy- I found it was about $3300 new. Nice power supply for sure-it doubles its power as impedance is halved all the way to one ohm! We have had similar equipment and talked before. Are you using the Krell with the Placette or with an active line stage now? Thanks in advance!

A tube preamp might make a nice combo with the Krell amp if it didn't compromise the bass at all. I still maintain that the Placette passive is the most transparent linestage I've ever owned but my situation required a more versatile preamp so the solid-state PS Audio PCA2 is what I'm using these days.

  I see that you've got a Denon receiver as an HT processor ( I assume running through the PCA2's HT bypass). Have you ever used the Denon as a preamp along with one of your other amps? If so would you comment on the difference in going from the Denon as preamp to a dedicated preamp (PCA2).
  I ask because I am currently using a Denon 3802 as a preamp for an HCA2 and am trying to choose between upgrading to a dedicated pre (prob. PCA2) or a better digital source for my next purchase. Thanks...

    Good question. Yes, I use the HT bypass in my PCA2 preamp. I have tried the Denon preamp but never bothered to listen closely for any differences (because I already had the PCA2). If I can set it up so it's not a 'hassle' to A/B compare, I will report my findings.

  If you check my old posts you will read that I did own (Bent) and also tried Placette. Great product each! My Krell Ksa-250 needs more than standard 2V cdp output....more like 3V for proper bass response IMO with my Apogees. I did and still own Apogee Centaur Minors along with Vmps supertower/r's and Vmps 626''s which need only about 100 watts to sound their best. My Apogee Duetta Sig's just don't get it with-out gain of an active pre. I did love the Bent TVC but needed more SPL in my new 25 X 22 X 9 ft. dedicated room.
  If your Krell will give full output with under 2V then this is another thought you may be interested in.

    Krell owner's manual says 1.34vrms input sensitivity and although a good passive might sound better, I need my active preamp for its versatility in my present setup.
    It would be interesting to try the Krell 'direct' from my CDP w/o a preamp at all. The DP-65V CDP has variable output via XLR or RCA so this is something I may try at some point.
