Hi Supakit,
a new from Italy; I suggest you for Jazz Music, to change before your pre-amp; the best choice is ARC SP 10 MkII, but is more expensive than 600-800 USD (sale your car and buy it!). For power-amps is different; it largely depend from the kind of speakers that you like, if these work in low impedance I suggest KRELL or similar; if work in normal impedance, you can try tube power amps (if you have high sensitivity speakers buy a good 7-8 Watts mono-triode tubes, if not a more powered amp, but always acording with speakers).
And remember that the final test is to listen in your room with your ears!
From Italy. Diver.
