    Crack;Bottlehead OTL

    I built the crack sold it and built T3 then bought a crackatwoa. The crackatwoa sounds just like the crack, but it is a much lower in noise with the tube shunt regulator and with a better power transformer. Like the crrack it gots a good midrange harmonics easy to listen to, but the treble is a...

    Sennheiser HD 600 Impressions Thread

    For me damping ratio (impedance load/impedance source) is a matter of preference. High damping ratio makes the sound tighter and thin sounding. Low damping makes the sound softer and thicker. Higher damping is generally better for most people, it allows for better control of drivers, it also...

    What's the best amp for HD800

    I built a crack in the past but sold it (my first real amp), the crackatwoa is just like the crack. Before in the past I had problem with the crack not presenting a wide enough sound stage, but the crackatwoa fixed that problem for me due to the shunt rectifying tubes. I think the crackatwoa is...

    What's the best amp for HD800

      The Super Dupont Resonator mod makes the HD 800 close to the HD 800S, by reducing that 6khz treble peak in the same way the HD 800s did it (with a helmholtz resonator).   The Rug Liner in question would be this one. https://www.rugpadusa.com/products/comfort-grip My impressions was it...

    Sennheiser HD 600 Impressions Thread

    for a $500 budget   I'd go with an upgraded Torpedo I or stock Torpedo III (or upgraded Torpedo III if you spend the money), it can drive all your headphones very well, unless you have inefficient planars. BTW it's DIY and very good value.   It's a summit fi amp, puts out a lot of dynamics...

    Sennheiser HD 650 Mod Compilation

    @mad max might want to put dynamat directly on the driver (after removing spider) in addition to dynamat on the housing, It reduces the reverberation the most.

    Chromecast audio - can anyone comment on sound quality?

    No, measuring jitter properly requires $100,000 lab equipment. Most manufactors don't even report jitter numbers. By ear the chromecast audio was tied for the most jittery source with my motherboard s/pdif optical output. (drop outs make chromecast less reliable than an computer optical...

    Chromecast audio - can anyone comment on sound quality?

    For everday normal use for normal people the jitter won't matter much, but for the audiophile it matters a lot. But for $35 it sure is great at the price point.

    I get tons of jitter from chromecast. So sound quality is meh. But it sure is cheap though.

    Koss Portapro Thread

    They going to be saying "yours is defective mines has more bass." Also portapro are open backs so puting it in a closed back headphone will have problems with the reflections from the back of the driver. They won't sound as clean as before.

    Sennheiser HD 600 Impressions Thread

    Found the chart headroom is down but I had it saved. The little bump from 7-9khz is amazing for detail, it isn't overdone like the beyers or HD 800, just perfect IMO.

    Sennheiser HD 600 Impressions Thread

    Check out the hifiman HE-6 frequency response chart it makes me think of an HD 600 with even better neutrality and bass extension. It also sounds like an HD 600 with better dynamics. The problem is amping it.
