I just don't have the system to fully do this lovely amp justice. This one's the baby of the mid 90's range and was designed from the outset for a balanced preamp to partner it, although it's just fine with a single ended preamp (passive's fine) with RCA phono plugs. Rated at 50WPC, the Stereophile review gave it nearly double this rating and of course, the power into 4 ohms is substantially more than this. Bass grip is legendary on these amps and unlike the earlier models Krell made, this one doesn't go straight into 'cooking' mode as soon as it's turned on, as there are three bias levels - idle, which keeps the amp barely warm after an hour left on, normal, after which the case warms up nicely and full bias for very high levels, where the case does get very warm.

This series of amps also offer good protection to the speakers as well as the amp itself. Prolonged thrashing switches the highest bias level off once the case reaches 80 degrees C until the amp cools down and although I've never tested this or the thermal sensor, there is short circuit protection as well since a 60A current swing is claimed.

All my listening is at low to moderate levels and Spendors apart, the speakers I use are simple and don't require the incredible load tolerance of this amp. Discussions yesterday indicate I probably have never heard what the amp can really do, as balanced operation was designed into it from the outset and not an add-on as with other amps.

I have a printout of the 24 page user manual which goes into detail on how the basics work and how to get the best out of the amp and also the chunky heavy duty shielded mains cable which I've only ever seen with Levinson amps before.

Collection only from just outside of Saffron Walden in Essex. I don't have a box, live too far out on the Suffolk coast and this amp is too bloody heavy to risk to a carrier in a third party package despite its diminutive size when compared to its peers.

I'm looking for sensible offers around £850 please which is roughly what the older and less capable model gets these days. It's a proper Top End product, built to last a lifetime or more and it deserves an appreciative system using decent sources and a preamp that will get the best from it and sadly, I'm not in that league any more.

The only person to have the top off is me out of curiosity only!

Very nice Dave, would be tempted if I wasn't so far away.

It's worth a trip. I've seen these go for £1.2K

I have it here and could send but there is no packaging. An amp of this weight can't just be dumped in a cardboard box, it needs something substantial. Either that or 'a man with a van' who could collect.

I would also have it if I was (a lot) closer. No doubt someone within striking distance will snap it up. Condition looks A1.

It is a great amp, but needs a better stereo home than I can currently give it. Had I the means to aspire to a good use balanced preamp (I had a Krell KRC series or early 90's Levinson in mind) I'd be keeping it, but domestic circumstances just don't allow this any more and the downstairs main system is hanging in there by the skin of its teeth as it is.

Amps like this may not appear to be that powerful on paper, but there's an authority they give to the music that seems unburstable. The HH VX300 I have here offers about the same wattage into 4 and 8 ohms, offers a large transformer (still under half the overall size of that in the Krell) and goes more than loud enough cleanly, but it sounds 'smaller' in comparison - can't describe it any better...

BUMP

Is a man-with-van (or small car) going to cost a fortune over a carrier? I'd have estimated cost of a carrier to be at least fifty quid, assuming I had original packaging.

For some of you here, an amp like this properly partnered will be the last amp you'd ever need as it easily reproduces changes elsewhere and will drive the vast majority of speakers out there with absolute ease...

P.S. It spent ten years of its life as a second amp and came to me because the previous owner, who's main amp was an FPB400, was going for and subsequently bought a D'Agostino integrated at a mere £47,000 (he's owned Krells for thirty odd years now).

MWAV are not overly expensive for fairly local stuff...say up to 40 mls. Across the country, if you got one to do it it would be expensive. Cheaper doing it yourself. Ups are best for largeish delicate packages as vans are better equipped and drivers care more, generally. Trouble with things that are so heavy the one man struggles to lift it is they will get dropped..

Nice amp by way..love it.:)

I've safely used UPS via Interparcel for medium size and weight packages including the Harbeths, which were properly boxed in the correct cartons. The Krell is like a large but heavy breeze-block and I wouldn't entrust it to a carrier as transit damage would all but write it off I fear.

Shame, I would deffo have it if you could ship it safely.

Can you drive anywhere Martin?

I was going to suggest. If you could get a quote from a friendly driver with car-van, perhaps we could come to some financial 'arrangement?' ;)

You have the perfect speakers for the Krell's charms too I reckon....

Dave and I have a mutual pal who used to travel your way, but I don't know if he still does. Actually, I've just thought of a mutual friendly sales-manager who might be able to help, although it's a huge ask........

Perhaps we could take it to PM?

Sure, but I can't drive anywhere on account of not having a car. Or a licence.
