    6SN7's and the Modwright Oppo BDP-105

    As a new (happy?) owner of a Modwright Oppo 105 I'm naturally curious about tube choices. The 6SN7 tubes in its audio section are popular low power tubes for any number of audio components, so what are member's favorite NOS choices?

    Rob,

    I always liked the CV1988 Brimar in my VAC's. I'm interested in a 105 myself as an option to my current tube DAC,of course it probably won't be a Modwright,but you never know. Glad you like it. Roger

    The VTV testers liked those Brimars also.

    I haven't personally played with this tube but a friend that uses the Icon Audio phono stage swears the NOS RCA destroys (ok I'm taking a little liberty here) the Shuagang replicate.

    The red base is supposed to be the bomb.

    When I had the Modwight OPPO 105 I tried a few different 6SN7's. The new Sophia Electric were very good. A touch intense. Tried the 5692 RCA red base. They are very nice and a little more laid back. Also tried some Sylvania 6SN7GTA's. These were a little more forward than the others but still very good. All these were clearer and more transparent than the stock tubes. Well worth the effort. Which you will like will of course depend on your system and taste in sound.

    I got the Sophia Electric tubes as recommended by Dan however, I've slightly prefer both the PSVANE CV181-T Mk II (http://psvanetube.com/wordpress/stor...cv181-tii-pair) and the Tung Sol 6F8G with a Woo Audio 6F8G/6SN7 adapter (http://cdn.head-fi.org/5/5b/5bdc1728_IMG_4311.jpeg). The latter two seems to be more relaxed and natural sounding.

    Another thing, replacing the tube in the power supply resulted in a warmer, deeper bottom end for me. The caveat being that you would have had to request the large hole cut in the case to fit them. I've got the Emission Labs 5U4G mesh rectifier tube (http://www.emissionlabs.com/html/pro...rectifiers.htm) and now the Phillips 5R4GYS (http://www.positive-feedback.com/Issue68/5R4GYS.htm).

    Cheers,
    -Hedwig
