Long story short: looking for upgrade my system. In general, I want to have simple system - one source (CD player) and amp. Last month I auditioned OTO Line Signature vs. Meishu Line vs. Meishu Line Silver. OTO was really good, but Meishu Silver made me almost cry - how beautiful it sounded, and how much more expensive it is, than I can afford... Honestly, standart Meishu didn't impressed me a lot. And lucky, I found pretty good deal on Audio Note P3 Silver (3oob tube amp) with a lot of upgrades. It's power amp, but with volume control, and could be used with one source. But I really don't get technical details about matching impedences between source and amp, and if it would be good match. At the moment my source will be my Yamaha CD-S2100 player, later on the road I'll try to buy Audio Note CD 3.1x/II one box player. Maybe people with more technical knowledge and Audio Note afficionados could help me with advise . Will it work with these specs, I have: Audio Note P3 details: - Input impedence: 100 KOhm - Input sensitivity: 450mV for full output Yamaha CD-S2100 details: - Output Level (1 kHz, 0 dB) SA-CD/CD: 2.0 ± 0.3 V - Output Power: SA-CD: 1.89 mW (max) CD: 1.36 mW (max) Audio Note CD 3.1x/II details: - Output impedance: Less that 2 kohm - Reference output: 3.0V RMS (approx.) Matching tube 8-10 W amp with my speakers shouldn't be problem - they are two way with simple crossover, 96 dB and 8 Ohm. Also, what I'll be missing and what sound properties, beside more inputs, should be better with, let's say, Audio Note M2 preamp?
