    New Bedroom System

    Hey Guys! Long time lurker here. I don't post much, but felt I should share my new secondary bedroom system. Just picked up a nice little Sansui A40 Integrated Amplifier and a pair of Koss Dynamite M80 speakers. She actually sounds really good for only being a 25w p/ch...

    Electrostatic Phones: membrane issues?

    Hi Folks, Not too long ago, I bought a near-mint, still boxed pair of early 70s, Koss ESP-9 electrostatic headphones. Obviously old, but in good cosmetic shape & seems barely used. After several weeks I found the time to hook them up. I wired the E-9 energizer to the back of my Kenwood 700M...

    where is the best place for me to upload a schematic ?

    I have a pair of KOSS ESP 9 headphones I bought many years ago. At one point in the past (pre-internet) I acquired a factory schematic for the energizer box for them. I just got them out of storage and plan to refurbish them and in conjunction with that I had the schematic scanned. I figure...

    Great customer service from KOSS - worth sharing

    I decided to make this a new thread since it could apply to more than just the product I originally posted about. The background: a few days back I posted about a need for some ear pads for my ancient Koss Pro 4A phones (the original model). I also happen to have a set of the original ESP-9...

    KOSS HHV-LC refurb questions

    I opened myHV1's to use some Deoxit F5 on the fader and discovered issues. A) - The thin piece of brown foam around the fader turns to dust if touched. B) - The driver magnets in the nylon housing seems to be plastic "welded" in place. C) - There is some sort of white debris on the opposite...

    What's with vintage headphones?

    Guys, I really need an opinion here. Anyone's two cents would seriously be extremely helpful because I don't have the best experience with any of this and really anything would be helpful! So, here it goes: I've had a very bad experience with buying professional headphones from the 1970's and...

    Koss CM 1020

    New member, getting back into vintage gear. I'm picking up a Marantz 2238B, and a Marantz 6100 TT tomorrow, and have a chance to pick up a pair of Koss 1020's but I am not familiar with Koss speakers. Will the 2238B dive these speakers, as they are larger floor speakers, and are they a good...
