    Pair Sylvania Gold Brand 5814a / 12au7 NOS NIB

    100 ohm cable

    1/4" male to 3.5mm female cable with 100 ohm vishay 1% metal film resistors on each channel, litz braid SPC wire. I used this to remove hissing from my Shure se530s when plugged into my desktop amplifier. I have since built an amp specifically for the Shures and so this cable is no longer of...

    Re-Tapping A Hammond 1455 Case

    I'm considering tapping a hammond 1455 case for 6-32 screws. However, the case currently has the self-tapping screws installed. Has anyone tried tapping for 6-32 after installing the self-tapping screws? Thanks.

    The MS1000 Review

    The MS1000 vs the K701 – this sonata’s only for one Beethoven’s Sonata for Piano No. 31 in A-flat major op. 110 This was never going to be a fair fight. I haven’t heard a headphone that renders a good piano recording so effortlessly and precisely as the AKG K701. On the other hand...

    PPA Instability

    A well worn topic here that never seems to go away. It is the hissing that results from using low impedance high sensitivity phones with the PPAv2. It is not a gain issue. I tried a gain of 2 which actually increased the hiss over a gain of 11 using grado gs-1000s. To me this indicates that...

    Audio_Technica Pricing

    It seems that AT is using a pretty extreme scaling factor for their retail prices. It appears to be about 0.38. Apply this to the retail price of the ad700 and you get the actual selling price of $95. Similarly apply this to the retail price of the w5000 ($1700!) and you get Headroom's actual...

    Is there something wrong with this picture?

    If you think the case should not be grounded this way (ie to the transformer bolt) please be specific as to why this is a problem in this build.

    Missing the 325s already

    I finally decided to sell my Grado sr-325s. I know there's been a lot of controversy over these phones, but I've always felt that with a good tube amp and source these sound amazing. The payment for these has come through and I'm missing them already. I want to hold on to them, but I'm telling...

    TKD 2CP-2511 datasheet

    Well technically a DIY dimensional photo. I wasn't able to find a datasheet before I bought this, and now I thought it will be handy for other people to be able to see the exact dimensions and decide if it can work for their project. There may be an actual datasheet out there - I didn't look...

    Mouser Boutique Nichicon

    Just noticed that Mouser is selling a lot of Nichicon "boutique" caps. They have KZ, FW, KW, HN, etc. Maybe I'm the last one to the party here, but I wanted to let people know if they're not aware. The HN looks very nice for low voltage applications.

    USB Powered Pimeta

    I'm planning to build a pimeta with tread that can be optionally powered by usb. When wall powered it will have 24V ac coming in to the tread. I will be using lmh6321 buffers and ad8610/20 op-amps. It seems I could bypass the tread and power the pimeta directly with usb as both the lmh6321...

    Does the Alps Blue cut it?

    It seems to have a reputation for being just about as good as it gets, but I'm really starting to wonder. What brought me to this wondering is that I have two identical "maxed" PPAs in my possession right now, except that one has an ebay stepped attenuator with solid silver wire and one has a...
