Somehow I think that even if someone listened to your favorite amp and didn't like it, his opinion would not be as valued as a persons who did like it.

Anyways, this is getting silly now. For the record, I actually have listened to an LDR-based volume control.....but not a buffered one like the Warpspeed. I didn't like the sound of it because I thought it was adding a sound of its own.
If we could agree that the job of a volume control is to only attenuate, and do so in as neutral a way as possible then we might have a decent baseline. However, I don't even think there would be a consensus on that.

Cheers,
Dave.
