I'm wondering if it's time to start keeping a table of how different op-amps, in what configuration, sound in Leckerton products. In part because I plan on getting a few to experiment with chip-rolling, and I've been taking notes on what people say here about them.
The OPA627 sounds like a pricey winner, but I notice Leckerton doesn't list it as an aftermarket item. Has anybody tried asking him about availability?
It looks like various op-amps are available pre-mounted on surface-mount adaptors through third parties, but I've been hesitating in part because I'm uncertain which op-amps are going to be better off with bypass caps, and which won't be.
