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


Hi All
Just getting started in this. I bought a pair of I.Q. TED 400 floor speakers(used - from Germany) and power it with a 1994 Harman Kardon AVR 20 rated at 65 watts. System seems to play well, but i want to explore a little and have decided to try some different power before i go replace the speakers. i read the personal amp evolution thread to get some of the brand names. I will only buy used as i expect to trade around for a while; min 100 watts. Right now the local used shop has some Rotel, NAD, Adcom and a Haefler. A used 200c Cayin is also in the area. Or should i just wait and buy the next level up?

Amc is not bad, but it's $400 amp, and musical fidelity is in a different league (higher).
My concern is that the Musical Fidelity (MF)seems to be quite old (also, whats up with its dimensions??? its so thin, I think its about 2" high where most higher end equipment seems to be quite a bit larger than low fi equip)

I don't have the budget yet for the MF and a pre-amp. Is the HK going to hold back the MF amp so much that i won't notice the hi-fi amp? I should be able to get the new pre-amp in the next few months. Or would you recommend the Adcom set instead?
MF will be a niticeable improvement over what you have now - even with HK pre-amp.

Adcom has great reviews - you can google search for them. That will be ok too. Can you bring them home and give it a try, before buying, with your speakers ?

That would be the best thing - try to bring the MF too, and hook it up to Adcom pre, and see which amp you like more - Adcom or MF.
