Speakers for a “cold” room

Before any upgrades in equipment,I would first acoustically treat the room. It sounds like you have room issues,not equipment issues.

Hi mlapenta, before turning your room into a ragamuffin I suggest you go listen to a pair of Magnapan 3.7i's. Dipole loudspeakers have one very major advantage over standard boxed speakers. They send very little sound to the sides, up or down. Standard speakers bounce sound off of everything, dipole line sources do not. The only room treatment you will need is some damping on the front wall right behind the speakers. You can add subs down the line. If you are into fine detail the Magnepans have arguably the best tweeter ever made. Since you have a squarish room you will have a standing wave problem in the bass. You could use multiple subs like many in this forum suggest or just move your listening position back and forth a few feet till you get the bass right. In just a few feet you will go from no bass to too much bass. 

Love the panels will cure everything argument.

The reality of a diapole is that half the sound is out of phase with the front wave and adding subs doesn’t compensate, also Mijostyn not everyone loves the giant disemobodied sound that a Magneplaner makes. 

A diapole’s real advantage is that it has a figure 8 dispersion pattern which helps with rooms where side wall interactions are an issue.

Mijostyne we have a lot of panel experience with Quads, Quad ESL 63 and even Magneplaners.

With that being said, if this gentleman loves the bass of the Adagios then a speaker with even better bass the Golden Ear Tritron 1R would work very well.

They actually throw a very big soundstage, and have both good resolution and a very nice tonal balance and the bass response is fabulous.

The OP should be looking at the Tritron 1R which are way better than the older Tritons.

We used to sell the Adagios’ so yes the new Golden Ear Tritron 1R would be a very nice upgrade.

As per electronics there are a ton of great electronics for the OP to look at.

What is the buget? We are getting fabulous results with our Triton 1R with the new Krell K300i a 150 watt Class A integrated and the Naim gear.

The Triton Ones will work wonders in your room.  

Harsh upper mids is a classic sign of needing to treat first reflection points.  I am in the camp of doing some room treatment first.
