Tube Preamps with Bass?


I love what a tube preamp does for the mids and soundstage in my system but I hear the loss of bass slam, weight and dynamics. I was looking at the Blue Circle G-3, Lamm LL2, CJ LS-17, First Sound Presence Deluxe, Joule Elextra.

Any opinions on these preamps or any others in the $5K or so price range mated to the Pass X-250 power amp and producing the added bass slam, weight and dynamics?

Thanks and Happy Listening.

Thanks everyone I was comparing the tube preamps to the Pass X-1 and on the same songs the Pass has better bass as I describe above. I would like to find one of these preamps that can come as close and retian the tube mid magic. I have Talon Raven C speaker and they do go pretty low.

Happy Listening.
Bigkidz,

I second Holzhauer's Thor TA-1000 recommendation. I had a chance to audition the Thor and compare it to the Pass Labs X-1 and the ARC Reference. The Thor has tremendous bass extension, great speed, liquid midrange and great top end extension. It easily bested the Pass and the ARC Reference. I bought mine used here on Audiogon within your price range.

If you have a chance, I highly recommend auditioning one before making a decision. If you're ever in the San Francisco area, feel free to stop by for a listen.
I don't know about the PASS X-150, but the older Aleph series amps had a low input impedance and if this is the case with the X150, you may lack some bass with many tube preamps. Try a BAT tube preamp with the 6-pak capacitor package. (See Drubin's response about an impedance mismatch which most other responders seem to ignore.)
Oldears I once owned the BAT VK-30SE and it was outperformed by the ARC LS-25 MKII in dynamics. The Pass X-1 also outperformed the BAT. The BAT did not offer the mid range sonics I am looking for in a tube preamp.

Happy Listening.
