Salutations my fellow geeks, and here we go again... So I have a pair of Duntechs sitting centre stage in my music room with nothing to drive them. And I'm poor. 😕 
I have two amps in the house presently. A Copland CSA 14 which is a lovely, warm, and reasonably punchy wee gem of an amp. Hybrid. Drives my Celestion SL600s very nicely. The other is an MF a3. Tis nice. Was bought as a back up amp but did quite well on the Duntechs... Until it cooked. So off to colinf it went and has come back to me with the caution that trying to feed the Duntechs with the amp is a recipe for disaster. 😳 Oops. So what to do? 

Ive had an interesting time with the Duntechs. Tried them. Didn't like them. Changed my mind and bought em and have had mixed feelings about them ever since. Granted I've never been able to feed them properly so it could be argued that I've never really heard them at their best. I can't afford a pair of fuck-off-big monos as I would like to and the market is limited for sub 2.5k integrateds. Second hand Krell? That's always been my plan. I reckon I could land a KAV 300i from Aus for around 2k. Or in the 'new' market, the Yamaha A-S1100 holds appeal and really reads well with both reviewers and end users. I've been quite surprised at who rates this amp and what they're driving with it. They have an RRP of 3k but are always 'on special' for 2.5k. How do the older Krells fare? Would it likely need a recap? What other options should I consider? What have you guys got in your cupboards? 😜 
The other option is of course, to lose the Duntechs. But I'm not certain I want to. And I'm not certain what I'd replace them with as I like to be able to swap between more than one pair of speakers. And I live in the middle of nowhere so there is a logistical nightmare with shipping these large and largely unknown behemoths. 

So lots to chew on and frankly, no great rush. I'd have to sell both my current amps to do any of this as we are saving for a house and there really is no money for HiFi at this point in my life. I'm just considering possibilities and would appreciate any thoughts or advice you fine gentlemen may be able to impart.

Cheers,

I had a pair of the Duntechs a few years ago. They performed well with three different amps as they succeeded each other in my then set up.

Plinius SA100mk2, Denon 3806 HT receiver, Perreaux R200iP. Went HT and used the Denon, until I added the Perreaux for the fronts via a processor loop.

Sold the Duntechs when I moved as too big for new place. Well, replaced them with Dynaudio Audience 85, and I guess they were not much smaller - definitely. It as tall though! Used my Mission 753s as rears, and despite many changes over the years, the 753s are the only items i have kept.

I would probably look for a 2nd hand Plinius, eg 8150, 8200, 9200. Perhaps even a Perreaux integrated of similar power. But none of these come up very often.

i bought my first gen krell kav-300i new in 1996, in the ensuing years it has never skipped beat.

in terms of dynamics and balls it has no peers, the locals don't come close.

coupled with wide bandwidth, transparency and ability to drive any speaker, it's a reviewer's dream amp.

however that doesn't make it an automatic choice as it's unremitting nature is oft mistakenly described as sterile and un-musical.

Greets from HB. What is the sensitivity of the Duntechs and is the impedance within norms? I had a Yammy AS700 in my system on loan for a week or so as I waited for another amp from my dealer. Long time ago but I was mightily impressed. I have a track called Bydlo - it comes from Mussorgsky's Pictures at an Exhibition (orchestrated by Ashkenazy). There is a point in that where there is a huge orchestral swell topped off with a sudden thwack on a drum. It is in the nature of the work that it has to be played at moderate levels. The amp has to deliver a lot of power virtually instantaneously. No probs for the AS-700. (Running Paradigm Studios at eh time).
