I have a ( used aprox 150 hour) SED EL 34 cryo quad ( actually 2 pairs ) purchased from Tube Depot ... I like these tubes very much but for some reason I like the un-cryod quad ( which is less sweet ) better than the Cryo'd quad ... Very modest hours aprox 100 - 150 .... I paid $160+ shipping asking $85 ...or trade for a new SED quad ( not Svetlana ) from either Tube Depot ,Upscale audio or any quality supplier.......Great chance for you to try the cryo' el34....
