Krell 65M's VS Krell audio Standards


Need some advice. Looking to upgrade a pair of MDA500's. Most of my system is Krell. Ref 64 with MD10 for digital, Accuphase tuner and Krell Audio Video Standard for preamp processor. I enjoy listening to jazz, especially vocals ie. Diana Krall, Patricia Barber etc. On occassion I do like to crank it up. Sonically, does anyone out there have any suggestions between these two pairs of Amps? Am I in danger of buying a 10 year old pair of KAS's and having servicability problems?

i would think the sonics of most krell amps are going to be hard to tell one from another. i met dan d twice. he told me himself the diferrence between old and new was not huge. i would buy the audio standards myself. best looking krells ever.
I have a REf. 64, MD 10, KRC HR, AVS and KAS-2s. I run Thiel 7.2s and BMW 801 IIIs. I liked the KAS2s so much that I just purchase a set of KAS. I have had no problems with Krell on their service and support of my older equipment. I have not compaired a KAS to the 650M. If you are looking for a KAS, expect to pay 11,000 to 12,000 for them. A set was just on ebay, but the owner did not let them go at 10,000.
i still say open up a audio standard, then open up the 650 monos. open up a ksa 250 or 300s then look at the 300 fpb. the filter caps went from the coke can size to the finger nail size. now was this to save money? i am not trying to beat up krell as i have met and talked to dan and the crew. i want a big krell to try on a sub, right now. anyway i think the audio standards were the best krells ever.
