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.

Outstanding advice on the big BAT amps.  They are a pain to deal with due to size and mass, but wow, what a great product.  Keep your eyes out for the 600 stereo amp.  I am wanting one of these myself and pass on the 600 mono amps I have.  Simply outstanding, powerful, bold, dynamic presentation.
We have a demo Vk 255Se which is a current BAT amplifier and unless you play super loud or your speakers are power hogs this will be a fantastic amplifier for you. 

We are no longer selling BAT so the price is really good, it has been barely used so it would be a great amp for you and the sound quality is exceptional way better than the older amplifiers you have on your list.

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. 
The thought about selling the speakers crossed my mind but that's gonna open a new can of worms for me. To be honest I hate to ship speakers.  I'm getting some new perspective in my search. Also i have driven the Solos with tubes amps to good results but they have such a deep, earth rattling bass that a good ss amp is a must. The search continues.
Audiogabby the Platinums were very good speakers and even though they are an older speaker by today's standards they were built to a very high standard. Phil Jones did an excellent job on these speakers.

So the real question should be are you getting the most out of them.

We would caution about buying a really old amplifier as many older amplifiers can require service when they are that old.

Good luck on your search.
