Best Used Solid State Amp for less than $5000?

I've vacillated back and forth between many options but after much deliberation, it appears that I've narrowed it down to two (Can't wait until the Spectron Musician 3 is available, I guess) : At the top of is the Plinius SA250IV, the bottom is represented by Moon W-5. Oh, and to complicate matters, if I can find a real good price on a Pass X250, I probably would consider that too.

Can anyone chime in and tell me what they think of the Plinius versus the Moon? The Plinius can be had for around $4500 with the Moon in the range of $2500 to $2700, quite a difference in cost. I like the idea of being able to use Class A on the fly (withthe plinius) , but does that present its own problems? Also, heaven forbid if I needed work on the unit and had to send it back for repairs. Lugging around 155# net and 185# crated is not my idea of fun...but the sound is what I'm after.

Two different animals. Go for the plinius if you have the cash to spend. FWIW, to my ears, the W5 betters the X250. Keep in mind that is my opinion. I've spent time with all three amps (dozens of hours auditioning for my next amp).
Cheers

if you can find a pair of Symphonic Line, RG4 Mono, 150 W, you will be very happy. they are so musical and powerful.

Pass Lab X350.

Coda manufactures several lines. The Continuum line is the lower end. They manufacture for several other companies such as Innersound and Legacy. I think these are more of a middle of the line product. Then they have their own "Coda" branded amps.

I compared my Coda Model 20.5 with a Pass X-250. The Pass had stronger base, but i thought that the Coda's mids and highs where cleaner and more open. I think it's a matter of personal preference.
