Amp recommendations


Hi all,

I'm fairly new to the hi fi world in general. I was recently drawn to the sound of a display Martin Logan Montis at a Bestbuy store even though I was there for something else. I never knew speakers could sound that good. I have since been doing lots of reading, on this site and elsewhere, and this week purchased a pair of the Expression 13A.

So far this is the only gear I have; just figured  I should start with the speakers. I just have no idea what amp to buy. Much less speaker cables/streaming gear etc. I think every time I heard Martin logan speakers demoed (I've visited several stores) they were hooked up to Mcintosh tube amps. I visited a local high end AV store yesterday and he was pushing real hard for me to get the Mac..particularly the MA7900. They're quite expensive though, are they worth the price premium over other brands? I'd really like to get an Integrated amp because I don't want a lot of gear and it seems like it would keep the over all price down some. I'd like to get something that would sound great for ~$5k give or take, new or used. I don't mind paying a bit more, however, provided the additional money makes a real difference in sound quality.

I must admit I'm not well versed on all the audiophile jargon and have no idea what ohms, impedance, crossover etc mean so it's a bit hard for me to even know what will power my speakers. I don't know if getting a tube or SS amp is better for my speakers. I just want an amp that's low maintenance and sounds great for a reasonable price.

I'd appreciate some recommendations from you guys so at least I know where to start looking. Please let me know if you need any additional info.

Thanks!
Chuck.

I've also had a ML/McIntosh combo for several years, both much older models, and I agree with the synergy. I have tried a handful of different amps with these speakers and none sounded as good as the Mac combo. I'm not saying you should just buy the Mac but consider it as an option. Pass Labs amps are also very excellent but I wouldn't go for anything less than their XA100.x or X150.x models for your speakers.

donvito101, I missed the bit about OP's question about only integrated amps but my brother had his ML Sequel II paired with the Pass Labs XA60.5 monos for a few years and we both agreed the overall sound quality was greatly improved when he traded them in for an X250.5. It just added more "weight " to almost every genre of music we tried, especially at lower listening levels. YMMV.
Given that the 13As have built it power amplifier for the woofers your amp will only be required to drive the panels. With that in mind, even with the low impedance at ~20K Hz, I can't see why a 4 ohm capable 200 wpc amplifier, especially a Mac, couldn't comfortably drive the speakers. Of course either the MC452 or a pair of MC301s would give you much better results but that would put you on a different trajectory which will require a more complicated equipment matching considerations. I have heard the SummitX model driven by an MC452 (direct feed from a Mytek Brooklyn) in a fairly large room and it sounded fantastic.
