I certainly like the sound of both, but the Matsu****a tubes come across as slightly more laid back in comparison. Especially with acoustic tracks that have a lot of guitar, the Voskhods seem detailed -- I can really hear the movement of fingers across the strings, whereas with the Matsu****a tubes I don't hear such string details as much. From others' experiences, does this sound about right for what I'm experiencing with these particular tubes? This will help me calibrate my expectations. I'm still waiting on a couple pairs of Amperex tubes (mentioned previously in this thread), but at this point the Voskhod tubes are winning.
After over a year tube rolling with all kinds of tubes in my Lyr - I have the same impressions. The Vokhods are very detailed, as you describe, you can hear subtle things like bells, back ground vocals deep in the mix, fingers sliding on guitar strings. It all adds to the realism of the sound. You need to give the Voskhods plenty of burnin, over 100hrs min. They open up and the foward nature will settle in, they're best after 200hrs. The thing I like about these - very quiet - a kind of inkly black background that music emerges from and dissapears into. As you go up the quality ladder, they get more sweet sounding, more detailed, wider and deeper soundstage, and at the very top of the heap this amazing flow. It's just so captivating, it draws you in ( and sometimes doesn't let go until a few hours have passed!). That top of the heap are the Voskhod and Reflector '75 and '74 silver shield with the wire getter posts. Man are they good! If anyone stumbles across the '75 version - I am a definite buyer! Please let me know! (Not the common dual getter post '75 Refektors)Edited by rb2013 - 3/6/14 at 1:29pm
