Cashflow is of course a relative thing but, looking at the cost of big Class A amps new today, the KRS200s are great value. There is a fairly ready supply at between £6k - £12k. They are nearly 35 years old now so expect service issues. I bought mine in the early 90s from a Krell dealer ex-dem. I paid £7.5k then. About 12 years ago I had them checked over, serviced and fully re-capped. That cost £3.5k then. But for £12k today expect them serviced and re-capped.
I reckon that's value and they sound great against today's big designs, many of which have been toned down for the green lobby and don't run in pure Class A right up to the top. And don't they look the business!!
