New amplifier recommendations needed

[G8YU]

I'm looking to replace the Arcam A80 and P80 that I'm using with my Mirage M7si speakers. I have the A80 driving the tweeters and midrange and the P80 is driving the woofers.

I've mostly been pleased with the sound signature and quality of the Arcams; but they never had enough power for the M7si. It's not that I want to listen loud; it has more to do with orchestral climaxes sounding a bit congested if I leave the volume up loud enough to plainly hear quiet passages. They also don't seem as revealing as I'd like of individual instruments in older rock albums. At times some sounds seem to be buried behind others; and I wouldn't know they were there if I hadn't heard them before. I guess some of this may be the fault of the speakers; but I'm not replacing them any time soon.

I'm rather reluctant in doing major upgrades in my system, not just because of the cost, but because there's nothing that irritates me about the sound I have right now. I just wish I could improve it a little and have some more power. Don't suggest a quirky or high maintence amp/preamp. I'd rather have a fairly good components that lean toward musicality than components that excel in only one or two areas and/or are artificially revealing (exaggerating detail or some tones).

My price point is close to $2500.
I took a few years saving up and planned on getting a Parasound Halo A21. This year when I was ready to buy it I thought I should first make sure it would fit in my cabinet. I quickly found out that I have no where to put an amp that is 20 inches deep and weighs 60lb.
I have some Schiit already and remembered they now have the Vidar power amp and Freya preamp. A Freya and 2 Vidars would save some money at just under $2200 with shipping. Just before I bought the Schiit, I stumbled on a revealing forum that showed some less than flattering things about a few Schiit products.
I continued my search by looking at the Vincent SP 331MK. It's case is a little smaller than the Halo A21 and it weighs a little less; but I still wished I could find something a bit smaller and lighter.
I was looking at Musical Fidelity when I discovered the PS Audio S300; and that's as far as I've gotten in my search.
Is there another amp or an integrated amp with at least 125 watts and is about $2500?
I'm close to going with PS Audio if no one knows of anything else.
