RHB Designs Rhumba 1.1 preamp

Spencer;

Thanks for the response.
Being a somewhat newbe to all the top notch components.
Can you help me, and offer a comparison to a ARC preamp sound or the CJ ET3 I just listened to.
i was hoping with the tubes( or tube rolling)  to get a warm, lush presentation( CJ style) vs super, super clean?

ps: Nice systems you have!

@sbank  The last time I was to Bob's he was working on the rollout of his own preamps.  I couldn't agree with you more regarding your assessment of Bob.  Really good guy who as you say is in it fir the right reasons.  He knows good sound and how to help you get there!

@frozentundra It's easy to change tubes to tailor the sound. Be sure to read up on the flavor that various brands provide. 12au7 tubes are a type that have been offered in many versions, so you should be able to get exactly what you seek. 
I respect both A. R.  & CJ preamps & haven't heard the ET3 so can't be to specific. Both brands have so many models each sounding different. If I must weigh in on  AR my only relative concern is that they sound  a little on the dry side of tonality, more so in the older ones. 
If you call Andy he can tell you more about which tubes they have good feedback on, etc. Cheers, 
Spencer
