“Ordered a matched quad of the CJ Special Test grade to try in my Rogue Audio RP-7 preamp. I think the stock JJ 802 tubes sound excellent, especially for the cost. Have about 50 hours on these Brimars and there was certainly a change for the better from initial installation to this point. Very nice soundstage, no harshness at all in the treble, and just a very clean and clear musical presentation.”

“Stunning performance. I already had some vintage Mullards but these just blew them out of the water. Big super tight bottom, upfront mids and sheer smooth highs. Totally in love with these.”
