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.

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.
