Replacement for DeHavilland Ultraverve


I have a DeHavilland Ultraverve. It sounds great, no complaints.  I need a little more functionality-mono and phase buttons are what I'm after. I see a Herron 2A preamp on Audiogon. Any other suggestions would be appreciated. The rest of the system: Bryston 4B SST, Bryston 4B (2nd zone), Vandersteen 3A Sig, Luxman E1 phono, Amadeus with Dyna 20 LOMC, Marantz SA14S1 CD/SACD. Balanced connections are not a priority for my system.

Hmmm... When I replaced my Bryston BP26 pre with an Ultraverve 3, I noticed virtually no difference in sound. At the time I was using a 4B SST2 amp. I expected the Ultraverve to somehow trounce the Bryston, but it didn’t happen.
I say this not to knock the dehavilland, but to praise the Bryston. It may have all the features you are looking for, and it will certainly get along nicely with your current amp.
Thanks, appreciate hearing from someone who’s heard both. The BP26 lots of flexibility for sure.
