Paul, the only battery powered equipment I had was a DNM pre -- 15 years back. The power supply was a rechargable battery, officially always plugged into the socket (purists had advised otherwise). It was particularly silent by pre-amp standards of the time (and the money: affordable) and thereby clear-sounding. A later model, conventionally powered (the "6") sounded better though.. probably due to better quality components and superior design.
Speaking of accumulators, someone suggested I try a military grade, 36 amp bettery to power the whole system. Allegedly, such accumulators are successfully used in submarines! Haven't tried this yet...
Cheers!
