We are starting to hear some nice reports on these tubes. I've toyed with the idea of giving a pair or two a try in my Atma-Sphere M60s. Please keep us posted as they burn in.
Sofia Electric Blue 6SN7
Just received a pair of these this morning and to say I'm delighted is an understatement.At $99 per tube I was so hoping it wouldn't turn out to be a mistake.Big sigh of relief and a bigger smile.After fooling around with various tubes,footers,and cables trying to clear up what I was hearing as a congested midrange when there were multiple instruments,this tube has done it.
I replaced the Sylvania 'bad boy' driver tube in my Aric Audio Transcend amp just to get a feel for the sound before removing the bazillion tiny screws in the LTA MZ2 to try them there.Well it's staying right where it is in the amp.The mids cleaned up immediately and the entire presentation seems faster and even more dynamic.The vocals retain their sweetness with no excess sibilance.I recently tried a new EH in that position and also in the MZ2 which gave me the clarity but they were relentlessly hyper detailed.
I have read some cautionary tales about Sofia tube's reliability but they mostly involved power tubes, so fingers crossed.I'll update if any problems surface.So far my perfect tube compliment is one Sofia blue 6SN7,two Sylvania 6SN7,four (new)Tung Sol KT150 power tubes in the amp.The pre has two 12AT7 Sylvanias and two (new)Tung Sol 6SN7.
