Then make your own amplifier;

The Gainclone is a 47 Labs Gaincard which costs anything from £1800 for the
Shigaraki to £4600 for the full Gaincard.

You can make a Shigaraki for about £40 to £50, honestly, no kidding, it's
true :-) And then later make a dual power supply to take it up to Gaincard
standard, if you need to :-) The circuit is so simple it's almost a joke,
consists of 9 components and has the shortest signal path of any amplifier.
It sounds great. Ask the blokes on the forum and they'll help you, they're a
wonderful bunch of people.


Based on an IC from National Semiconductor !

"The LM3875 is a high-performance audio power amplifier capable of delivering
56W of continuous average power to an 8 load with 0.1% THD+N from 20Hz to 20kHz"

Hardly groundbreaking performance !
