    based on my listening on Freya: Psvane CV181 TIII > Sophia 6SN7 ≥ Northern Electric 6SN7. The Sophia's excel at space and nuance. Northern Electric is very similar, which they should be considering they're very, very similar construction. From what I've seen, the differences between the TJ Full Music/Sophia/Northern Electric are minimal, if any at all. NE 6sn7 was a little more closed in, but this may be due to lack of break-in. I admittedly didn't spend much time with the NE 6SN7 since they seemed so similar, sonically, to the Sophias.

    edit: I'm also fairly certain the NE tubes are made in china by TJ Full Music.

    I've got a quad of the NE 6SN7 tubes for Freya - came with the Freya which I picked up used.

    Agree with @yotacowboy, they are definitely open and spacey. Super clean sounding and tons of tone/timbre, but I find them a bit hot/etched in the mid-upper treble. Running a quad of them in Freya I find a bit too much- so I only run a pair of them in the right side gain stage, and a pair of smoother 50s Raytheon GTBs in the output buffer. Makes a nice combo. You lose a bit of that space, but less fatiguing.

    @Garns I read you are using Freya's passive mode by now. How come?

    Short story: various things have changed in my system which mean that passive mode now sounds better.

    Long story: I have quite long cables from my Yggy to my active speakers (3-4m). The input impedance on my speakers is low (14k). The Yggy is still Mk 1 with its relatively wimpy output stage. All of which is a perfect storm if you're trying to attenuate passively. When I first got the Freya the tube mode was superior: it had more drive and energy and less harshness in the treble.

    Since then I changed my cabling from Mogami 3080 to unshielded OCC copper. Seems this is way easier for the Yggy to drive. I also now have weapons-grade line filtration (PI Uberbuss). Taken together this means I don't hear the harshness and lack of dynamics I used to hear in passive mode. Set against that, tube mode seems to drops low level detail and microdynamics, regardless of which tubes go in. I think it's inherent to the Freya circuit.

    My only gripe with the stock tubes is that they are often noisy, I then mute the Freya, tip the tube with my finger and unmute Freya again. Sometimes I have to do this several times until the noise is gone.

    I assume, this behavior will be gone with new tubes?

    Thanks for the hint to Electro Harmonix a few weeks ago, but you didn't write anything about sound. Since I am finally going to buy new tubes for my Freya now, I wonder how these differ soundwise from the stock tubes?

    1. Tung-Sol 6SN7 GTB

    2. Electro Harmonix 6SN7

    3. Electro Harmonix 6SN7 gold pins

    Thank you :)


    EDIT: I found only one opinion on the Tung-Sol in comparison to stock tubes.

    Don't waste your time with the EH 6SN7 - I've tried the gold pin and it's crap. I can't imagine the regular black base is any better. I think both of these tubes are actually made by Sovtek.

    Do you mind to explain why you think they are crap? Two other people recommended them here, although not saying anything about the sound.

    I guess Tung-Sols will do ok, since they are Schiit-approved.

    What do you think about the rag - freya combo?
    Do you recommend buying me the freya to put in a combo with my ragnarok?
