    Tell me about Tungsram and other eastern block countries vacuum tubes.

    I have a ton of Ei tubes, and for the most part I like them. I have some Tesla labeled tubes (plus the JJ versions). Any way I have yet to hear a Tungsram or RFT tubes. So what are the opinions on the various former communist vacuum tubes?

    Stax SRM-1/MK2 hum question

    Equalizers: Digital or external which have you tried.

    Eq used to be a nasty word for audiophiles back in the day. My first stereo I bought back in the mid 70's, I added a passive Radio Shack on, and from memory, I thought it sucked, caused all kinds of phase shifts. As of late, the Schiit Loki Mini seems to be a big sensation in the Headphone...

    Transformer output with tapps for headphones?

    Just curious if such a beast exist. A headphone with multiple tap's of a transformer would indeed be a nice item. Tap's such as 16, 32, 64, 150, 300 and 600 ohm from a transformer coupled amp could be interesting. Speaker power tube (and McIntosh SS) amps have 4, 8 and 16 ohm tap's so why not...

    I am guessing there had to be some produced i the 80's and 90's. Of the portable cd player's I owned, I seem to recall they were all single bit delta sigma players.

    With the exception of the ESP-950, does koss only have 2 types of drivers? The one in the PortaPro and the one in the KSC75. And those may be the same drivers except for the titanium coating on the one. I suspect all the full size cans have one of these 2 drivers in them. Am I wrong for...
