Wind instruments have a 'breathiness' to the notes which I love, same goes for vocals. Valves really bring out the detail of instrumentation far more than solid state. Through the Yaqin its actually very interesting and easy to listen to music. Listen through my Denon and its very 'Meh, put something else on'. I'm finding country and jazz music sounds incredible. Since getting this amp its caused me to listen to other types of music rather than just my usual 60's-90's rock. I need to save for better speakers dammit! :tongue: Now to try supress the tube rolling bug which seems to keep biting me. I know the 12BZ7's are meant to be somewhat microphonic due to the long plates, though hoping some tube dampers will help with that. The 12BZ7's work out to $25 each and the 6N2P-EV's about $5 each so if they work well I'll stock up on them. I only have the 1 pair of the Raytheon Black Plates, and they're quite expensive/hard to find compared to the other two. I'm hoping that the 12BZ7's or 6N2P-EV's are as good or pretty close to the Raytheon 12AX7 Plack Plates once I try them. My understanding is that they take some time to burn in. I'll give them another try down the track. It's just that the JJ 6CA7's sounded so amazing after burning in that I couldn't handle them. I did try the Soviet 6N3PS-E's and found them neutral and closed sounding, though to be perfectly honest I didn't even wait for them to warm up properly let alone burn in. More detailed than the stock Shugangs but less 3D, still much better than my Denon SS amp though. Sounded more like a particularly nice recording (which it was) rather than actually being there in the audience. Mullard Reissue 12AX7 + Raytheon 6414's + Svetlana E元4b's were a nice detailed combination but seemed to lack the 3D stage / presence. Nice and tight, low noise and good right through the range. The Raytheon 6414's were so good in the 12AU7 spot I didn't bother going looking at other tubes for this position and ordered more as spares.

The Amperex Bugle Boys sounded similar to the Matsushita's. I quite enjoyed the Matsushita's with these though the Raytheon Blackplates were noticeably more detailed without being an overpowering presence in the midrange. The JJ 6CA7's are scooped, or a little lacking in the mid range but with excellent lows and high's which made other tubes in the pre section with stronger mids sound particularly good without it being overpowering. This seems to give an incredible amount of detail with nice even lows, mids and highs.

Raytheon 12AX7 Black Plates in the 12AX7 spot, Raytheon 6414's in the 12AU7 spot and Current production JJ 6CA7's in the E元4 spot. The current configuration I'm running is as follows: Soviet production 6N2P-EV's + socket adaptors I still have some valves on the way to try, though the current setup already sounds so amazing that I can't really see how anything short of a new set of speakers can improve upon anything.ĥ0's production 12BZ7 Long Black Plates with D getter '57 production Raytheon Black Plate 6414'sĬurrent production Shugang E元4 which came with the amp '63 production RCA Grey Plates - O Getterĥ0's production Raytheon 12AX7 Long Black PlatesĬurrent production Shugang 12AU7 which came with the amp I've done a bit of tube rolling since then and rolled the following tubes:Ĭurrent production Shugang 12AX7 which came with the ampĦ0's production Baldwin branded Matsushita 12AX7 Long Grey Plates - O getterĦ0's production Canadian Made Amperex Bugle Boys (Westinghouse branded) Still great compared to my Denon SS amp though. The stock Shugang valves sounded great once burned in, with a particularly good 3D sound stage although perhaps a little rough sounding. It powers some Sony SS-F6000P speakers (which I hope to replace with Bowers & Wilkins 683 S2's when i save enough). I ended up getting a Yaqin MC10T 3 months ago based on the many good reviews of the 10L, both on here and elsewhere on the net, marking my entry into tube audio.
