Mrjstark,
I'm sure the RWA 30.2 sounds great with the Dodd preamp, congrats! I was highly considering the Dodd pre, but Vinnie at RWA is close to releasing the RWA Isabella and it is also a tubed preamp on SLA battery power and there is an option for a NOS dac built-in. I have talked to Vinnie about his preamp design and I know he is voicing it to be very special with the RWA amps so I just have to be a little patient. Vinnie sounds very confident that he has something pretty magical with his Isabella design and based on how much I enjoy my 30.2, I trust him 100%. Can't wait to order one when it is ready!
Maybe you can "borrow" the Isabella on a 30 day trial and put it up against your Dodd and let us know :-)
