Amp evolution ques. - what comes after a Harmon K?

Keep in mind that Musical Fidelity P170 is a power amp, and it needs a pre amp like Musical Fidelity 2A, unless your CD player has a volume control built in (probably not).

Adcom pre amp will also work with it. Adcom combo is ok too.

Take the time to hear them your-self, and keep the one you are happy with.

You might want to read a book on hifi - if you have the time - as recommended on the thread above - you will make a more satisfying decisions down the road.

Many people getting into this exciting hobby stays on it for life - ever improving and tweaking. Reading a book on the subject will be a good start.

If you don't have the time, you can ask questions here 'til you are satisfied.

Adcom combo is a pretty good choice - if google search for reviews, you will get positive feedback on them.

I hope you find good sounds at home...

Welcome to this exciting hobby.

Do you think that using the HK as my pre-amp ( it has pre-amp output jacks) taking too much away from the increased amp quality to make it worth it?

I would plan on picking up a nice Pre-amp in the used market if you do get the Musical Fidelity - Pre does make a quite a bit of difference...

You don't want a low-fi unit holding you back, in your nice mid-fi system, and that's what the HK would do.

Especially true with LP. Make sure the Pre you do get in the future support LP, not all of them do these days.

Anybody have comments on an AMC 2445 amp?

Amc is not bad, but it's $400 amp, and musical fidelity is in a different league (higher).
