I ordered a matched quad of the new APOS Ray Select 6SN7 tubes to go in the Freya+ in the living room system, the Psvane Horizon CV181-AT (6SN7) will go into the Freya+ in the office. BTW, the Horizon tubes are getting better with every use... I have them playing the classical FM station in Santa Fe right now, they have become very well balanced as the bass decreased a bit which sounds better(still plenty of it when called for). The mid range is very dynamic and the highs are just so sweet. Beginning to love these things..
The Ray tubes are supposed to sound better, so I figured I'd get a set before the upcoming tariffs jack the price up 50%...
Experience the warmth and clarity of vacuum tube sound with the Ray 6SN7 Select, a hand-selected and rigorously tested tube chosen by audiophiles, for audiophiles. Crafted to surpass the unpredictable quality of New Old Stock, this brand-new tube combines the best of traditional materials with...

I have had the Ray 6SN7 Select tubes going for around 50 hours now... I thought they were merely OK, until I realized just today that I had not done anything to the settings on my Loki Max EQ: they were still set for my 1950's Sylvania 6SN7GTB chrome dome tubes which have a lot of bass, a bright mid range and a very sparkly top. I had the bass set to neutral, and the mid range and highs turned down not quite half way. I reset the Loki Max to neutral on all settings and these Ray tubes came alive!
The Loki Max has 15 positive and 15 negative steps per control and the frequencies overlap quite a bit (these are generalizations taken from a couple tests I saw on YouTube):
20HZ goes up to around150hz, the
120Hz control extends from 80 to 300Hz, the
400HZ does 300 to 900hz, the
2 Khz goes from 1000 to 3500khz, the
6Khz does 4000 to 10,000Khz, and the
16Khz does 11000 to 20,000Khz (seems Schiit kind of picked a number in the mid range of each control).
After playing FM radio, streaming on the NodeX, CDs, and several vinyl Lp's I ended up witha decent base line for these tubes. I have the 20, 120 and 400Hz turned up 5 clicks (up 1/3), the 2Khz set at neutral, 6Khz set at -3, and the 12Khz at -5 (down 1/3). With these settings the Ray tubes are magnificent: dead silent, zero microphonics, sound stage is wide, deep, and high- they are 3D "holographic" as all hell. The Psvane Horizon tubes I bought just before these sound very very similar but were a bit microphonic sitting on the top shelf in the main system, but they are working very well in the office with the Freya+ sitting on the middle shelf with 1.5" of maple butcher block above and below them.
