McIntosh C28 Vs. "Modern" Pre

How does a fully restored, vintage preamp like a C28 stack up against some of the more modern options out there today? Keeping it under $1000 (about the price of a restored unit from AudioClassics), can I do better with today's technology? I'm currently running an AudioClassics restored MC2100 paired with a Rogue Audio SixtySix Magnum that I got for a steal, but I've often wondered if pairing my 2100 with its contemporary preamp of the day would yield better results. I have no complains about the sound of my current setup, and I really dig the warmth of the tubes, but I guess the question of "what if" is always in my mind. Thoughts?

Suggest you ask exactly what "fully restored" means. All new caps? What else?

Also, isn't AudioClassics policy that you can listen for 30 days and return for full credit/refund if you pay the shipping? You can listen to the C28 and be the judge of what you hear.

If you are willing to spend roughly $1K look for a restored C29 and stay away from anything older including C28.
C29's are not easy to find but you can find one if you are willing to wait.
Look at the big auction site, almost half of all Mac preamps listed are C28's and for a good reason.

The new McIntosh amps/preamps have electrolytic coupling caps, for whatever reason.

There is a lot of them for sale because they sold over 22.000 of them.

I am currently just finishing up the revised power supply for one to match up with a restored MC2105.

The C28 and the MC2105, paired up, are an American audio icon.

I have a fully restored C28. Terry Dewick did the work for me.

I never listen to it. I find it dull and lifeless. The phono stages have never worked.

I now use a fully restored Audio Research SP-6B, and it's so much better than the C28 it's not even funny.

Just like they always have.

How can it be "fully restored" and the phono stages never worked?

If Terry D did the work and you are not using it, I would be interested.....they can be made to sing.

Cheers,

David

Cosmetically restored or electronically restored...there is a lot of work to be done at "wholesale" to keep it under that price if it is truely restored.

Hope to have an A/B this weekend along with the companion MC2105.

Ask Terry DeWick. He had it on his bench twice.

Not that I have any problems *at all* with his service or skills. He refurbed two MC30s, an MC2505, an MR74, and a C28 for me. I think that C28 is rotten or something.

I think you should then donate it to the cause for a documented exorcism! Can't take the chance it might spread to your AR and other equipment.

I don't know if we mean the same thing, but not all McIntosh amps use electrolytic capacitors to couple audio signals. The classic MC30, MC60, MC70, MC225, MC240, MC275 from the 60s/70s all had non-polar film capacitors for coupling (amongst them the famous Sprague Black beauty caps). The MC250 seems to have a 10uF electrolytic coupling cap in there somewhere, same as the MC2105 or C28. I'll never understand why.
