Audio Input Switch with Remote Control

I built a nice Class D power amp and paired it with a couple of vintage preamps (an Adcom and a Hafler). The Adcom died a few weeks after I got it, and the Hafler... well, just didn't sound good.

So... I'm wondering if there is such a thing as an Audio Input Switch that has a remote control to be able to control volume and input switching... and that's it. No "coloring" of the sound.

Currently, I'm not using the Class D power amp, but am using a Sherwood RX-4503 receiver. Does anyone know how much such a receiver might be coloring my sound, even if I'm running the tone controls flat?

Is getting a very "passive" audio input switch a good idea?

If so, can you recommend one to me. I need the remote control for volume and input switching. I don't need the tuner part... I can get FM through an ipod or my smartphone.

Thanks for your "inputs".

Audio Alchemy DLC (digital line controller)

They pop up fairly regularly on eBay, just need to make sure you get one with a remote and also that it works as repair would be a bitch w/o schematic support etc.

I believe that one does have a built-in loudness circuit that has to be defeated if you want 100% linear operation, but there are notes on the mod on the internet.

Teledyne made one like this too, called the AR-SRC. Pioneer did as well but they are harder to come by. The Audio Alchemy piece is probably the best of this type of device, at least for older gear. Seems to me I saw something more modern recently but the brand/model escapes me...

Thanks, John, for the suggestions. I'll attempt to chase them down and inform myself about them.

Wow... the Audio Alchemy is spendy $$$. Seems to me, that there's got to be something less costly.

I don't understand (that's true of a lot of audio stuff for me) why something so "passive" as a switch box would cost so much. Or, is it the remote control electronics that is so costly? Switching from input to input... is it that involved, the circuitry?

Oh well....

Well, the switching is electronic, via IC. Could be that technology was spendier at the time, esp. when done to a high performance standard.

Audio Alchemy was a boutique maker that specialized in relatively affordable but fairly high performance DAC's, CD transports, ant-jitter processors and such. The DLC was probably a fairly expensive piece at the time but was being sold to analog equipment lovers that wanted the convenience of remote control with little to no impairment of their glorious analog sound. They may have overbuilt it to some extent, but that approach makes them collectible today.
