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!
