McIntosh Preamp

Thank you for the input and I sure will.

Not that I would use it because I haven’t listened to FM radio in 15 years. Does the tuners of yesterday MX-130 receive radio signal transmitted today?

Yes, as long as it is a standard (over the air) FM signal. You will not be able to pull in "HD" or digital channels without a separate HD decoder. Some of these decoders are coming packaged with networked audio players, which could provide more flexibility for you. Something like the Denon DN-350UI.

Generally speaking compared to other manufacturers McIntosh preamps come with tons of knobs (tone controls) giving the end user ability to shape the audio signal the way they want, this feature happens to be the the big seller among Mac fanatics, over the years Mac made two preamps with minimal features and I have both of them, one is C29 and more recently C15. I typically listen with preamp in flat mode with nothing in the signal path, both preamps have done a good job, the C15 which is my current preamp in use is very quiet and just what I expect from Mac minus all the bells and whistles which offer nothing for me.

@Vahes, totally agree, iwould prefer not having them but to each his own. My other systems preamp doesn't have tone controls either and that's what I'm use to. 
@the group- I've taken the plunge. I an MX-130 from Audio Classics. I believe it arrives Thursday. I feel the price was fair and I dealt with a guy named Steve Rowell who was super. If all is well after receiving it, I'll definitely be back to Audio Classics.
