Thanks guys, that's great to hear.

I always come across buried threads from AoS and can easily (and happily) lose an afternoon or two if not an entire weekend!

So much knowledge here.

Anyway re my SET amps I've tried the Quads with a Minute EL34 offering from Asia but due to its zero negative feedback design it can sound a little lean with them. I've had a lot more pleasure listening to them via a super cheap (but actually well respected) Gemtune/Nobsound/-Insert Chinese re-badged generic design name here- EL34 amp with some tube rolling which has been a revelation. As previously mentioned it shouldn't work particularly well but in my room with my system it really does. Only 8wpc but for my listening levels its more than adequate.

Current tubes are:

Psvane EL34B's (I have some 6CA7 TII's to try soon also!) - The ones that came with the amp are the black base version but I have a matched pair of brown base ones.
Tung Sol 6SL7 pre amp tubes (I have some NOS Tung Sol's on the way!)
Svetlana Winged C 5U4G rectifier tube (I have a NOS RCA one to try as well)

Just a little note on the Psvanes - it might just be in my system but to me after 20 hours or so they sound absolutely majestic. Superb tight bass, slightly forward but magical mids and some nice sparkle in the highs, I'm not sure why they don't have more of a following. This in comparison to Gold Lion KT77's, Svetlana's, Groove Tubes, even some NOS Siemens and Tesla's I've tried. Admittedly I've not pulled the trigger on a NOS pair of Mullards but have to draw the line somewhere!

I should quantify I'm also using a Rel T3 subwoofer in the setup just on low settings with the crossover around 70Hz just to underpin the low end of the Quads. You hardly know its on, until you turn it off that is. Unless I have a truly huge full range speaker I don't think I could listen to a setup without a well implemented sub now!

I've tried the same setup with two T3's, one for each channel but the improvement was not really audible at my listening levels. Also I think it "excited" the room too much which messed with the imaging a bit.

Of course its not perfect, depending on the recording the volume and "slam" of the sub can be too much/too little but its a compromise like a lot of things.

I would actually like to get a REL with remote control for this purpose one day . . .

Regarding amps I'd love to try an old Radford in my setup.

(Apologies if my posts are a little long or in the wrong place, I'm not quite up to speed with the online etiquette as of yet!)
