Hyperion HPS-938 speakers

Different experiences and performance with the same speakers or same line of speakers means one thing. As with all speakers, their performance is highly dependent on the associated electronics, front end, wires, room, AC, isolation, etc. -You need SYNERGY-

Based on the high opinions of your speakers, Hawkeye43, I'd keep the 938's and build a new system around them.

Well I pulled the trigger, I purchased a McIntosh MC-207. It should be here around Wednesday. Looking foward to getting it in and seeing what it can do for the Hyperions. Curious to see if it matches up well with my Nordost and Audioquest cables. If not there will be some cables for sale. My local dealer says that Mac and Nordost match up well, his opinion (he is a dealer for both). If not,there isn't many other options here locally. Will have to go to somewhere like the cable company, and in my experience they are spotty when it comes to service. They do have a huge selection of cables though.

Hopefully, this is the start of building a true "higher" end system. Next will probably be a pre-amp. But that is down the road.

Congratulation on the excellent amp your purchased!
Im almost sure that is going to match perfectly both with your speakers and your Nordost cables.My friend your problems are probably solved.
Happy Listening!

Just received my new McIntosh MC-207 it today. I installed it in my system and notice right away of more bass than my Arcam amp. The soundstage seems tight and the highs are sharp.

Are all these sighs of a new amp just trying to run in? if so how long does it take?

3-4 weeks , 4-6h on average per day should do it.
It won't change much after that. IMO.
You should hear its true capabilities and character after or around first 100h.

Congrats on new amp.
Don't worry , it will cool off with time .
Cheers
