I am looking for a pre-amp to match my headphone and future speakers system. I have P70 cdt, dac wadia 64.4. Now i really want to buy a pre-amp to match my sr717+007a. I have a pair of speakers which is krell lat2. I like big 3d stage, clear, thick and smooth, detailed sound. My main music style is jazz and classics. Any recommendation you can give me? used price i can afford is around $5,000
