PS Audio BHK lacking..

I bought a used PS Audio BHK preamp to replace my Rotel.  It sounds thin with no depth & bass compared to my Rotel so I let it run for over an hour with no change. I'm new to tubes so I'm looking for ideas. New tubes or what?

I was thinking to replace my parasound jc2 with BHK preamp for the last couple of months, but looks like other experiences and opinions r so controversial. Now what I have is big big doubts. Should I do it and will SQ get benefited from it !!!???

fertguy-Is it possible that your speakers are out of phase? That could cause what you are describing.

No, I’ve solved the problem. It was old tubes. I’m new to tubes so I spoke too soon. surfmuz, don’t hesitate because of my screw up. Mine is sounding much better w/new tubes.

@surfmuz   It's a worthy preamp.  I ditched a VAC Ren Sig II for it, as it quite convincingly sounded truer to the music in my system.  For the money, especially used, it's a good value in sound and function.

Another big question...- is hybrid preamps like BHK much better in bass aspect then full tube units like Modwright or VAC ? Did anybody compared same price range preamps with hybrid and full tube circuitry?
