    Like many of you, I need something to do during the Quarantine. I'm going to have a lot of free time on my hands. I've already built Pete Millett's NuHybrid Headphone Amp, Butte Headphone Amp, Starving Student (Gen 1. A failure, but I learned a lot from it) and have also built the WHAMMY...

    Is there a scientific way that intentionally creating "hard to drive" headphones could lead to better sound?

    WHAMMY DIY Build

    I have decided to build the WHAMMY DIY Headphone amp, as it looks fairly straightforward. I got interested in the project after finding the PCB on the diyAudio store. The build guide is a little bare-bones in some aspects, but there's schematics, pictures and it's detailed enough that you can...

    RMAF 2018 - Tickets bought. Anyone else going?

    I secured my tickets for all three days. Last year I went for two days and really didn't see as much as I should have. Mostly hung out at CanJam, but I think I missed out on seeing a lot of good stuff. I know it's kind of a ways off, over a month (Oct 5 - 7), but I thought it might be...

    Massdrop THX AAA 789 ending shortly. First measurement posted.

    I've been interested in this amp for a while and now it's near ending. I don't know if it was due to my complaining about the fact that there were none, but they've posted a measurement on the website. I was wondering if anyone could take a look and tell me what you think. I'm not very...
