    Vera Audio P400/1000 Review (Amplifier)

    Out of curiosity, where does this preference, and/or the opinion come from - that having no front power control = superior industrial design? Other than minimalist aesthetic, why is an accessible power control on an amplifier bad? Genuinely interested in answers from anyone with an opinion. Thanks!

    Dan Clark Stealth Review (State of the Art Headphone)

    Finally, no EQ recommended, just awesome. The industrial design is quite appealing also. Well done, Dan Clark!

    MASSDROP Sennheiser HD58X JUBILEE Review (Headphone)

    I'm the owner of the 58x sample for this review, can confirm they were purchased for ~$135 last year. For what it's worth, the 58x's 150 ohms is enough for a good match to my OTL headphone amp. They also respond well to SS amps, so one of the more versatile headphones I've tried.

    Balanced DAC - Audible Difference Likely?

    An interesting question, and I'm in the process of upgrading to balanced (I/O) right now to hear what the differences are. My biggest draw is the extra voltage potential with balanced. But I read at Rod Elliot's site that there is potential for degradation of CMRR (noise rejection ratio) due to...

    Balanced Line Output from MiniDSP 2x4HD (help!)

    Having a problem with my first balanced set-up and could use some advice from the more experienced folks. I have a Loxjie P20 headphone amp, which features balanced XLR 3-pin inputs and balanced 4-pin output. I'd like to feed the balanced inputs by fabbing a custom cable and driving with a...

    Superlux HD668B Review (headphone)

    I own both pairs of the HD668 that Amir reviewed. One is still new in box, the other I've used regularly for about 3 months. I've compared the HD668 against Sennheiser 58x, AKG 371, Beyer HD880, and Beyer HD770. I have no experience with AKG 240 or Superlux HD681 EVO. Aside from comfort issues...

    Does Phase Distortion/Shift Matter in Audio? (no*)

    In my experience with building passive crossovers, I've noticed phase shifts can result in variances (boost/cancelation) in frequency response of a multi-way system (relative phase to different drivers). This can be compensated for by adjusting the crossover points, or using other methods to...

    Does Phase Distortion/Shift Matter in Audio? (no*)

    I understand at the moment the signal phase (entire system) is flipped the switching may be audible, but listening to 0° and 180° samples (entire system) should sound identical. This would make for an interesting blind AB comparison.

    Well, it's now obvious we're in a post-truth era!

    Why are all tweeters 1 inch in diameter ?

    Thread was a good read, but I agree with @dorirod. This thread feels out of place in Reviews, and may seem as an error in the long-term.

    Superlux HD668B Review (headphone)

    One idea is to use a Bluetooth module with built-in mic. Connect to the stereo plug on headphone for a wireless gamer/conference headset.
