I read your other thread. For what it’s worth, I have heard from two sources that McIntosh works very well with Martin Logan speakers.
Sorry, can’t stop thinking about possibilities. Here’s a radical idea. Get the following and pair them together:
- Krell Foundation 4K
- McIntosh MC303 - 3 channel amplifier.
You might be surprised. The MC303 retails for about $11k I think, but it has come up for sale for about $6-8k used (though rarely). There’s actually one on ebay right now with starting bid of $5800 (plus freight shipping, the thing is 188lbs in the box!!). You can get a nice, but low cost amp for surrounds (for now). The surrounds don’t have to match exactly, but they need to be in the same "ballpark" as far as sonic signature goes. The front 3 channels are the most critical to match sonic signature.
There have been several revisions of the Krell Foundation. Krell has already made a new hardware board to support 4K, and there could be other revisions as well. Definitely several firmware versions. I would look for the latest version on the used market, the "4K’ version for sure.
If the Krell didn’t give you what you want as a 2-channel DAC/preamp, you can always add an external 2-channel preamp in the future to create a "hybrid" system, such as a McIntosh C50 for about $4k, and still be somewhat within your $15k budget.
