Preamp with Tone Control Recommendations ....

Get a D'Agostino Momentum preamp for only $32,000. Sure, it's a little pricey but hey, you get tone controls.

I got the Mcintosh c 2300 and its fantastic with my Threshold SA4e.It is the best pre with tone controls (maybe D agustino is better?). And you can steer the tone controls via the remote. Thats unice and very handy. It a shame that the bigger Mcintosh get rid of tone controls. Many manufactures claim that tone controls damage the sound. I have had numerous high end pres and the C2300 is better that any of them

Ha!

I had the D'Agostino Momentum. Sure it has tone controls but they are not independent and have no zero point. So that means once you engage them you HAVE to use BOTH bass AND treble. Not an ideal solution and frankly annoying at that price point. I do have to say it was one of the finest sounding preamps I've ever heard. If it had properly designed tone controls, I would have been happy.

Effischer and Ulf,

Thank you. I had the C2300 two years ago and I'm sorry I sold it. The C2500 would be the logical upgrade and the DAC might be a bonus (as long as it sounds good).

Sure I believe tone controls affect the sound, maybe not damage it. But once you cross that line, it dosen't seem to matter.

My ideal preference in the McIntosh line would be a C500T (or even the C500P) with the tone controls of the C50, totally bypassable of course.

Thank you for all the suggestions, please keep them coming.
