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.

@twangy57 gosh, higher input impedance, doubles power into 4 ohms.  I am thinking maybe this would work well with your pre and your speakers:

Here is a discussion on Agon about this model Krell comparing it to a Coda amp.  Both were complimented in the thread:

I already committed to the purchase of a Conrad Johnson Premier 350sa

It has 350 into 8 ohm's,and 600 into 4 ohm's.

Thanks
