Looking for an amplifer

So I currently have a Mcintosh MC2500 that went for some warranty repair and was damaged in transit. Instead of the audio store calling and telling me, They tried repairing the physical damage and not tell. After the warranty repairs were done and the amplifier shipped back to me. I promptly noticed the physical damage that they were not able to repair/replace when I called them out on it they then said the amp was damaged in transit and they spent a lot of hours trying to fix the physical damage and that since I wasn't happy they would just pick up the amp and refund my money.

So that has me in the market for another amp. My budget is 3k/4k. What I have found thus far are the following:

1. Another Mcintosh MC 2500 $3200 silver face not black like the one that was damaged.

2. Krell FPB 300c for $3900

3. Classe CA 400 for $2600

4. Pass Labs X350 for $4600 over my planned budget.

Has anyone had experience with these amps that can provide some feed back on what they liked or didn't like about them?

My speakers are Dunlavy SC4
