I challenge anybody with either of these two units to try this, Open both covers, using the appropriate size torex (Easily get at a Canadian tire). Loosen all the torex heads holding down the transformers, and the pcb boards. You can even do it while its playing its so easy.
Everything factory comes tighten down to much. Loosen it up for nicer relaxed sound that keeps the sounds stage nice and tight. The effect is immediate but leave it like that for at least a week to see if you like it.
