Big Krells Have Vanished From The Used Market

 class A or D  well I own both   NAD -m33 and 23   700 watts

also krell evolution 400  ..I switch back in forth  the nad is the cleanest and pin point imaging I have ever had in 30 plus years of high end audio driving  Kef reference 5 meta,  love the warm engaging sound krell   but love the sound of the nad  one does not need to spend thousands of dollars to to a top performing audio system -would   I buy  amplifiers  in the 25-30k range and expect higher level of sound reproduction  ..no just different  owned them all over the years

The longer an item has been out of production, the lower its circulation. That’s not specific to Krells. But big Krells have the added disadvantage that they’re heavy as hell, hard to even move a few inches, and extremely costly to ship. Plus they may need service. These serve as a barriers to re-entering the used market. Risk is high (for both parties), and reward is much lower (depreciation).

That said, I’d like to think the remaining good units have mostly found long-term homes with owners that are really enjoying them!

Which service tech is it? A few of them charge more than krell does.
