    Tutorial - A tale of 6 amps THD+N and THD specifications

    Trust the numbers? Maybe not so much. Another Grim Fairytale on why I hate numerical specifications for audio components, especially THD+N and THD. This is a brief, visually oriented tutorial. Prerequisite reading: Tutorial - Interpreting THD and THD+N specifications and graphs...

    Tutorial – Interpreting THD and THD+N graphs

    Typical audio device specifications include distortion specifications which are published as follows: THD less than 0.02% THD less than 0.02% at 1 KHz THD less than 0.02%, 20 Hz to 20 KHz, 0 dBu, 300R load The first specification is meaningless. It provides no information about the measurement...

    Seattle Summer Meet Impressions, Broadview Library 7/28/18

    Another interesting meet. I enjoyed the opportunity to hear the Ananda planars (thank-you Tim), DNA Sonnet 2, among a number of auditory experiences. Had fun explaining my system to many. There were pictures taken and maybe some of you will share them here. John's 2A3 was definitely a sight to...

    yggdrasil - gungnir MB - bifrost MB - a terse, ribald comparison

    Having all four of these Schiit multibit DACs is a considerable privilege. Comparing them to other DACs with printed words is challenging at best. These need to be heard, preferably in level matched A/B comparison to other DACs, to fully appreciate the advancements achieved by Mike Moffat and...

    yggdrasil technical measurements

    2015.12.12 update - THD measurement corrected.   I will never know how the first three hours of the yggdrasil sounded as I let the DAC warm up for an hour and proceeded to make technical measurements. If the measurements presented are familiar territory, then you should be as impressed as I...
