Bolder is offering 2 tripath amps. The modified TEAC (30 watts) and a battery powered model (9 watts@4 ohms.) My speakers are Triangle Titus' (90db-4 ohms-C/O to tweeter only, with a powered sub.) With my modest listening habits, I'm sure 9 watts will suffice. So, how does one, choose one, when one, can't listen to one???
Also, I'm presently using a quality 1K Stepped Attenuator from a Sony 555 es to my Mac MC-122 with a 10k input impedance with excellent results. Will this attenuator work with the above 2 amps?
