Mods for a PS Audio HCA-2?


I recently purchased a HCA-2, and I like it so far. But I was wondering what improvements I would hear, if I were to consider modifications? Thanks, Sonny

The thing that folks need to understand about stock components is that they may have great frequency response with a steady-state signal, but they usually have dissapointing transient response. Mods are the only way to fix this. Power delivery to the active devices is the problem. The capacitor types and locations, the wiring topology and wire types make a huge difference here. A typical sotck amp may have great bass response and reasonable mid-band transient response, but lousy high-frequency transient response. Unless the transient resopnse is UNIFORM at all frequencies, the music will not sound live.
