Filter tweak for digital backwash?
OH! Almost forgot to mention, it has been shown that a lot of the noise from a laptop or PC isn't "noise" so much as a ground loop. Obviously, it looks like noise, but the fix is entirely different. For these you need a ground loop isolator. Here ... 
Filter tweak for digital backwash?
The least expensive unit I recommend, based on a lot of research this one:http://amzn.to/2h9R4Z4Series mode power surge suppression also includes noise reduction that works down to about 3kHz, and that noise reduction is bi-directional.  Most nois...

Smaller speakers but not smaller sound is my goal. :)  The LM-1 kit I posted is a reference quality monitor but specifically designed for a bookshelf or desktop.  By making a "true bookshelf" it has a lot of advantages for sounding great, sounding...

Sorry about the broken link, there's an extra https:// at the end. The correct one is here:https://speakermakersjourney.blogspot.com/2016/01/introduction-to-georgia-tech-leach.html 
What is optimal frequency for front tower loudspeakers for movies/music
80 Hz should be fine. What are your alternatives? :) The only thing you gain by going up is you reduce the power required slightly.  Much higher than 100 Hz and you'll start to be able to hear the subs. That's not what I would worry about at all. ...

There is a software solution, ffmpeg, that should be able to tell you whether a track is redbook, HDCD tagged but not used, and real HDCD. It's not that useful unless you want to conserve disk space though. :) I mean, it's kind of academic. Best,E 
HDCD rescue - it's possible, but man...
It’s quite possible some real HDCD disks also never did the labelling. :) I could check my recordings, I suppose, but meh, it’s all automated. That Patricia Barber CD with the HDCD label really IS HDCD though. :) Sorry I think there’s some misund... 
HDCD rescue - it's possible, but man...
All the evidence I see so far points to:- PM gear in mastering process turns HDCD flag on.- Engineers don't use any features- CD's get mastered with HDCD "data tag" but no features used. - Label gets printed without HDCD because it's not real. - S...

Hi @ptss Well thank you kindly. I was very fortunate to be able to observe a true master, Dr. Marshall Leach Jr. when I was very young. That exposure sparked a life-long interest. My humble memorial to him is here. Later on I was able to work in c...

@dtc I'm sure the mistakes were honest. :) I only meant to point out that many think they've discovered unmarked HDCD disks (like a bonus track on an album) when in fact they are plain-Jane Redbook CD's. This is probalby why they don't have HDCD b... 
Class D Technology
I've been living with ICEPower based amps for six months, I don't hear any of the issues being discussed, and my speakers have extension beyond 30kHz.  
Berkeley audio alpha dac
Magico uses them pretty often for demo's, so they can't be very bad. :) Personally while I appreciate them for being extended, detailed I also find them a bit cool. Not hard or harsh at all, just cool. I prefer the Mytek Brooklyn's in terms of tha... 
Ayre Codex - to keep or not to keep
Hi Lee!! The gold standard is Jensen. Very expensive, but very very good. I make these converters from German parts for far less, but still very good. Best,Erik  
Ayre Codex - to keep or not to keep
I would keep it and add an output transformer. :) Best,Erik  
Class D Technology
Tim, If you can't hear the difference, stop! :) Unless you are a QA professional, learning to tell the difference in equipment you couldn't hear before doesn't lead to better enjoyment. I traded in my class A/AB amps after evaluating class D and f...
