Krell MD10R and SBP-64X DAC - help?

Can anyone tell me how good the above combination is?

I have been offered one for $5k and wonder whether this is a good purchase given the advances made in CR replay since the Krell combination was launched.

I know the combination is good, but just how good?

Please help!
I would go for new technology.

The MD10 is beautiful and does function very well.

I had the opportunity to buy the Reference 64 D to A ($14,000)for just $2000. At the time, I had the Krell Studio($3900). I asked a friend at Krell if I should buy it, and his response was that I should not. His reason was that the sonic difference was slight and that the "64" was more delicate and very expensive to fix.

I followed his advice.
