Mizike,
I would give serious attention to the Atmasphere UV-1 preamplifier, . When you take into consideration the Designer and his company's pedigree this UV-1 could be a very exceptional product. The output impedance is only 400 ohms and would be easily matched with your power amplifier. It utilizes the 6SN7 tubes which is a good choice IMO.
