Passive preamp vs. powered


I have a custom made passive pre-amp that I purchased from A-gon some months back for about $150. It only has a volume control and 2 inputs - perfect for my needs.

It sounds excellent...

My question is... what would be the advantage of a much more expensive powered pre-amp? Sure, maybe I would have powered switches and more inputs, but I don't need any. Are there some differences in sound quality that I'm not hearing?

There could be. Don't you have a powered pre you could A/B with? Passive pre's work great, but it also depends on a few technicalities. Since the whole idea is not to influence the source signal, there is no amplification of the source. Sometimes, depending on your amplifiers, there may be a situation where a slight boost is needed to attain best performance. You will have to experiment to get an "ear" on the situation. Placette makes one of the best passive pre's in the market. I have been looking for a RVC (remote volume control) from Placette to use with my Wyetech Opal.

I have a Creek OBH 12 Passive (with remote) and an Audio Electric Supply (AES by Cary) AE3 tubed pre. While both sound good, the AE3 makes accoustic guitars sound more like wood and vocal just sound better. You must trust your own ears.
Happy Listening
