Pass labs krell parasound amps


Hello, Looking for feedback on the best sound and reliability of these amps, how do they compare to one another. Looking to spend 5-6k on used amp from these choices: Pass Labs x250.8, Krell Duo 300xd, Parasound jc5 or Mcintosh Mc312.

I have Mark Levinson no526 preamp and Revel 228be speakers and like a very open, transparent sound with deep soundstage. 

Thanks for your response.

@testpilot I am sorry to say that I have not got the opportunity to listen to the new XD series. In Sweden there is no hifi dealers that have them for demo so there is no chance to listen before buying and it is to much money to just buy without having the chance to evaluate. Krell had a "dark" period, I think it is after the Evolution series, with some series of, according to me, bad quality and sound. I am reffering to some KAV products and multichannel gear. I believe they now are back on track with the XD and i series. I prefer my older gear even if the are enormously powerhungry and gets hot because they work in class A and, my Infinitys sounds wonderful and needs huge class A amps. One must be aware of that they all need a recap and renovation but with that done they will sound amazing for another 25-30 years.

Thanks for the input. I think I have narrowed down between the Pass Labs x250.8 and the Simaudio Moon 870a as both have great reviews and power range I'm needing between 250-300 wpc. Although the Mcintosh is interesting.  

@dcclone Krell = Krona?

I am very happy with my old Krell KSA-80 which has needed a couple of repairs over the decades.  Class A with no power saving gimmicks.  Good room heater!

An extra thousand should get you a X350.8 used if not a bit less but when the deal pops up it will go quickly. Many have reported the 350 superior in many ways to the 250. I have the 350

Piebaldpython. I don't think my rack will hold the weight of the 350.8 or it could be an option. Thanks
