Warm romantic & detailed

Because I rank it close up there with the Harbeths and Spendors recommended by others, I'm going to mention the Vienna Acoustics Liszt again.  You can get exceptional bargains on used examples if you keep your eyes open.  

Rather than swap out equipment or run separate software do you guys think adding the mcintosh men220 to my system would help? 

The Mac uses room perfect lyngdorf's room correction. It should work fine but you could get a Minidsp DDRC-22D  for $700 and use Dirac. 

Adding the Mc MEN220 is running separate software in that it is the Lyngdorf room correction and is a pricey solution at $4500.   It is also not certain to solve your problem.  I find Lyngdorf amps sound a little bright even with room correction engaged but I am not an expert on the implementation and engagement of that software.  

It might be cheaper for you just to get new speakers.  You should be able to get $2800 to $3000 on trade for your speakers if you have original packaging.  More if you sell them yourself.  Out-of pocket would then depend on the exact model you look at.  

For example, the Spendor D7.2s list for $6800.  That would means $3800 to $4000 out of pocker for a new Spendor vs. $4500 for the MEN220.  

If you were my customer that is roughly the deal I would offer for the Spendors.  

Another interesting speaker in the same price range would be the Scansonic MB5 B.  List is $7200.  Scansonic delivers a huge soundstage and is very natural sounding.  You are supposed to set them up off axis as the speaker is designed to use reflections in the room to deliver a deep and immersive soundstage.  

Trade allowance would probably go up a touch vs. Scansonic compared to Spendor but you get the idea. Whoever your dealer is, should be able to work with you to get to a smart solution that will resolve your issue and keep your budget down.  

Definitely - the Harbeth 40.2's, or 30.1 or 30.2's will provide that type of sound with the right DAC, Preamp, Amp - such as the Hegel H360/H390/H590.  I've got both, and that is they type of sound I get with the H590.
