Need insight on these amps


I just sold my power amp and a few other components. Looking to buy a first class amplifier for my Platinum Audio Solos which are a difficult load but I like the way they sound. Right now I see the following amps available in different websites:
1) Krell FPB 300
2) ARC D-400
3) ARC 300.2

I would like to hear from anyone who have heard these amps in the past what is their opinion on them. I'll be using a tube preamplifier. I'm also open to suggestions on amps that retain their value over time. Thanks in advance for your time.

There’s a McCormack DNA-1 Rev A available at US Audio Mart for $1400 that’s sure worth a look.  I have a DNA-0.5 Rev A and I can tell you transparency and expansive 3D soundstage are two of its strengths among many others.  The DNA-1 should have plenty of power to drive your Solos as well.  Best of luck. 
What amp did you have? What are you looking to improve upon?  What amp and overall sound characteristics of a system are most important to you?  Without this info we’re just throwing darts in the dark.
