How to switch between two pre amps & 1 power amp

Thanks All,

My Classe amp will swtich inputs from the front panel control.

This will give me the cleanest 2 channel audio pathway.

Plus... i get to go listen to some new balanced cables.

Current plan is Synergistics, MIT and Acoustic Zen!

This is a lot more fun then an AB switch.

Thanks

I use 2 preamps with my Classe CA400. I use 1 preamp balanced and the other single ended. And just flip the switch on the back to choose balanced or regular.

Yep, what Reubent said....and thats how I do it.

Reubent is right on the money.

There's a better way (IMHO). Just run the L&R pre-outs from the receiver to any unused source inputs on the LS-15. Select this "HT" source when you want to use in HT mode. You will obviously have 2 volume controls in the loop, so you will need to determine a consistent "known reference volume level" on the LS-15 and use that position whenever you are calibrating or listening to HT sources.

Basically this is similar to the experience you would have if you had an HT bypass on the pre-amp. The only difference is the need to set the volume control to the "known reference point" (something like top dead center or a predetermined number, etc) whenever you play sources connected through your HT system. Whenever playing HT sources you would use the volume control of the HT receiver.

BTW, I've used this type of setup many times and it is not an issue at all for me. You just need to remember to set the volume control on the LS-15 to the know reference point when listening to HT sources. Otherwise, the calibrated volume of L&R speakers will be either too low or too high (ouch!).

Enjoy,
