Tube Amp recommendation

since you are going high efficent speakers how about trying the OTL route with atmasphere's 30 or 60 watt amps?
OTL is supposed to be audio nirvana!

Dissing the Primaluna , for the reason that you have listed , is doing yourself an injustice !
Try reading about it here on the 'gon .

Good luck .

I got one out of curiosity and I am quite surprised by the sound. The build quality is not like a Shanling or Jolida. But the sound stage, range, clarity are astounding. Replacement tubes are available from a website in London. I was told that the tube was used in Russian MIG aircraft and is therefore military spec. Life expectancy of 50,000 hours.

I have only had it a week. If it lasts, great sound and a real bargain.

It might be one of those premature ideas but hay......lets see where this goes (I would not suggested it to someone who likes to pick his stuff from the magazine's recommended list but someone with the vision and imagination....and confidence in his/her decision making). This is actualy something that worked - at least in this case. I have kind of came about this after my recent experience (work on my amps) with Bob of RHB Sound Dezign and my best friend's plunge in, on new Emerald Physics CS-2 speakers base on my stupid advice ( no, it has nothing to do with speakers. He just bought Cybers 211 mono-block that he dreamed about and was going to use them with high sensitivity speakers-not CS-2s). It turned out that his rushed and emotional decision wasn't entirely thought through. His budget like the Ice Age melted away and his (new) system's performance/existence became big question mark.
He was in desperate need of quality amp (that will match his Cybers 211) to drive the CS-2 bass drivers in bi-amp configuration (which is necessary and a must with this speakers). His target amount for that miracle amp was $500 ( possibly )now or $1000-$1250 in at least 3 months (but speakers would have to stay in the box).
Solution:
Since I was part of the problem, I felt that it was really necessary to find the solution to hi$ problem. Solution that would not only work for the time being and sort of a temporary fix but an actual way to make this setup work, and work well.
What we came up with was an excellent inexpensive amp (used from AgoN) that excel in the bass department, that also had a good design foundation and represent good value (now and resale). It will serve its purpose now and when time i$ right he will get in touch with Bob and try to get the most out of this amp as possible within the budget ($600-$700). I believe that with Bob's help he will be a realy, realy happy. And his system will be the WHOLE and then some.

Used Rogue, Jolida, just noticed nice pair of Wright Sound 300B mono-blocks for under ($900)(knowing George Wright reputation and modder Bob Backert's love for tube gear and good design. I think it would be a perfect amp for future upgrades. This amp had some work done - so it is already tweaked to some point. But still, I am sure some of Bob's magic dust would make this a truely great peace to own (I don't know the seller in any way, shape or form). Sometimes there are realy interesting peaces on sell for grabs but you have to know what it is that you are looking for. So keep your eyes open. Happy hunting.

Good luck &

The Rogue Atlas bought with the MAGNUM upgrade is a steal for the extra $600 it transforms a good solid amplifier into a Excellent one .The tubes are upgraded to the EH-kt-90, resistors are upgraded, power supplys heavilly beefed up, caps are the excellent Mundorfs from Germany that are then Bypassed with 1% poly caps to make them even better.better connectors and some wiring modifications .
What a difference IMO this amp nows betters the stereo 90
and for under $1800 over 90 wpc.
Highly recommended and looks retro cool.
