Matching a amplifier to speakers


Hello.

I had a thread a while back on picking a amp for my system.

It was suggested that I pick my speakers first as to not make a costly error.

I ’am back now that I have bought a set of speakers.

Just to reiterate my currant modest system is as follows,

Auralic Vega g1 streamer/dac

Rega p6 turntable with exact cartridge

Nackimichi CD player

McIntosh MX110 tuner/preamp

Adcom GFA-545 power amp

My currant speakers are Polk M10’s

The new to me speakers are Dynaudio Focus 360’s

I listen to 70% rock,pop,and blues and 30% jazz and classical

My listening space is 13x20 

My budget is 5000 or less.

I have read that these speakers need a lot of currant and a good amount of watts to sound there best.

I would like to go ss if possible,as my preamp is fairly warm sounding,but I’am open to suggestions.

Since I have been looking at audio gear and buying a couple new items,I have tried to re-evaluate my listing habits and goals.

I have a general habit of starting each listening session with a known favorite at modest volume,and see where that takes me.

Sometimes I do get inspired to crank some loud rock for maybe 20 minutes,and then return to regular programming.

Since getting tidal and a streamer,I have rediscovered the joy’s of exploring unfamiliar territories.

I say this to try to express my need to have a amplifier that can do rock,yet have the ability to check out new styles with clarity,and accuracy required.

I know it would be a good idea to go to a bunch of audio shops and shows ,but I'am probably not going to do that .

I will most likely narrow it down to a couple,then go check them out.

Thank you.

I looked at the schiit tyre,but it has a input impedance of 47k.

I'am looking for something near 100k or more as Mcintosh recommends for my MX110 tuner/pre-amp

thanks

Why not buy a McIntosh Amp?

Mike

Which one?

All the solid state amps have a low input impedance around 20k ohm's,which means they won't match well with my preamp's output of 40k ohm's

 If you mean tubes, which one has over 120 watts that I can get for 5000,or less?

Thanks

I’am starting to think I should maybe switch my pre-amp to a Conrad Johnson or another pre that has a lower output impedance.

I wonder why the MX110 has such a high output impedance,as the C-22 is only 220 ohm’s?

Is it a result of the FM tuner?

Lots of variables involved.

Thanks

I know you’re thinking SS, but if you consider tubes, the MC 275 would likely play nicely with the MX110. My ancient McIntosh XRT 20’s have comparable sensitivity to your new Dynaudio 360 speakers, and my 275 drives them admirably.I purchased my very low hours MK VI 275 from Audio Classics for $4999.

I originally planned on going tube,but from everything I have read and what people on here that have owned the Dynaudio focus 360’s have told me is,they need at lot of power and a lot of currant.

I also think with the warm nature of the mx110,my system might benefit from some clarity offered  by the right ss amp.

I have been looking at the Mcintosh amps,just need to think on it some more.

I just know some people have said these speakers seem to like at least 200 watts per channel.

Thanks

For what it is worth:

My Futtermans are notoriously fussy about load. Since I am married to the Futtermans, speaker choice comes second: find a pair that matches up to the Futtermans. 

Except that I already owned the Altec 694Cs. 

Which, coincidentally, paired up magnificently with the Futtermans. Pure luck.
