Comparing 3 Tubed Preamps. Impressions?


I've narrowed my search for a preamp to the following 3: Audible illusions L2 (same as M3a sans phono stage), Blue Circle BC3, and the Herron VTSP-1A. I'm currently using a Pass Aleph amp (with a 47k input impedance so a tubed pre shouldn't be an issue). In time I might consider a same-family amp if the synergy is there. I can listen to the Herron, but not the other 2, so I'm looking for impressions from anyone who has compared them or any mix of them, or has any comments on any one single unit. I have experience with a passive pre and like the transparency and neutrality, but need more dynamics and bass punch. Much appreciated!

Hi:
Your search-set sounds kind of like the one I came up with about this time last year (and I too am located in an area where there aren't dealers nearby and was moving to tubes from a passive pre). To your list I'd also suggest adding the First Sound Presence Deluxe and Joule LA 100 MK III. I ended up buying a used Presence Deluxe and a Joule LA 75 Mk II, figuring I'd keep the one I like more. I auditioned each one for a month or so, starting with the Joule. The Presence has not left my system.
The Joule is a great preamp and has the benefit of a standby setting, where the tubes remain warm and ready to juice up. On the other hand, the FS has an attenuator for each channel which is a definite advantage and a separate power supply, but no standby function. I just leave mine powered-up all of the time if I'm going to use it every day. Other than that, it has a bit too much gain than I prefer, meaning that I only use the steps between 7 and 9 o'clock, and when it is turned all the way down, it still produces sound.
I suggest you check out the reviews of each one in the Soundstage
archives. Good luck. Regards, Jim
