Bypassing A Preamp With Volume Pot In Amp

I see preamps as a convenient tool to control the volume of multiple sources. It only adds another link in the chain. It also adds to the cost of your system because you will need other pairs of interconnects and a power cable.

I was thinking about completely bypassing a preamp by adding a volume pot or a resistor based stepped attenuator into the amp, greatly reducing the signal path from the source to the amp.

The only detriment I can think of, is switching the interconnects from each source which is as troublesome as switching out a disk from the CD player.

Please chime in with your opinions and especially your experiences with this "issue".

The volume control I have in mind is the Khozmo stepped attenuator using 2 Vishay TX2575 resistors in a hybrid tubed/ss amp.

C,
Just ask George which is better. What you are considering doing OR just buying a Lightspeed attenuator and another pair of less expensive rca's to bridge the connection. I understand where you are coming from wanting to keep the rca's of the same quality within the chain, but I'd bet the lightspeed with some mediocore interconnects will sound better than what you are trying to do. I could be wrong...

Ask George what he thinks. By the way, I have no relation to George other than being one of many, many happy customers. His lightspeed thread is one of thelongest here, with glowing reviews!
