Error Correction during CD replay // Super Black Hole from Herbie's Audio Lab
I will try to find something.  For now read this:https://en.wikipedia.org/wiki/Compact_disc 
Error Correction during CD replay // Super Black Hole from Herbie's Audio Lab
Cros-Interleaved Reed-Solomon Code (CIRC) allows to recover data from up to about 4mm scratches along the track. Between 4-8mm data is interpolated while scratches longer than 8mm cause dropouts - at least for the most of CDPs working in real time... 
Mixing speaker cables on bi-wired speakers
Twoleftears,  I suspect that there are many cables like that.  I had one from Audioquest.  My current cable Acoustic Zen Satori Shotgun has two indentical cables for high and low - each about 1 inch in diameter (gauge 10) 
Anyone With A Class 'D' Amp Play A 4 or 2 Ohm Speaker?
Where is LIKE button??? 
Mixing speaker cables on bi-wired speakers
Using different gauge for upper and lower terminals might affect speaker's frequency response.  I understand that woofers take more current, but low/high ratio will change - tweeter cable will have larger (percentage wise) voltage drops.  Most lik... 
Anyone With A Class 'D' Amp Play A 4 or 2 Ohm Speaker?
One of our past Audiogoners had class D Icepower amp (H2O), rated 2 ohm min, driving 1 ohm nominal Apogee Scintilla speakers with great results. 
power cords with active shielding
I did read everything but unfortunately cannot think of anything else, especially since Al and Ralph already commented.  It could be the power cable, speaker cables or both.  I listen to recorded noise and watched youtube video showing sound of di... 
power cords with active shielding
Jim, speaker cables are antennas for the electrical noise since amplifier has low output impedance only for low frequency signals.  Induced noise enters amps input thru the feedback loop.  As for the ferrite - on one hand you need highest permeabi... 
power cords with active shielding
James1969,  It is possible.  I had for few days CB like transmission loud voice coming thru pretty much everything at home - TV (turned off in stanby), speakerphone, radio.  I noticed every time the same unmarked car with many antennas passing by.... 
power cords with active shielding
James1969, Yes, twisting signal wires will reduce it - if it is coming as common mode.  In the case of power cord your signal wires are hot and neutral (return).  Pitch of the twist should be many times smaller than wavelength (17" for 700MHz) Twi... 
power cords with active shielding
Power cable hot and neutral conductors are carrying the same current in opposite directions being, in a sense, "balanced". Twisting them will make them exposed to external fields evenly causing cancellation. Same goes for radiated field from the c... 
Bridge Rectifier for the heater 300b tube amp
Using heftier diodes (and the bridge), as George suggested, is always a good thing.  The problem with rectifiers is that at the peak of the voltage they should stop conducting (being suddenly polarized in opposite direction), but in reality curren... 
Musings on Switching Power Supplies (LPS for Oppo / DirecTV/ Radiance)
It all depends on how SMPS is designed.  They got bad rap from crude computer applications, but can be extremely quiet and are line and load regulated.   Many manufacturers use SMPS for the reason of lower noise.  Benchmark got 10dB S/N improvemen... 
No-one talks about Rowlands anymore
Rowland is going down for 30 years.  Perhaps Jeff Rowland doesn't know about it and keeps releasing new products?  Might be good idea to call him and let him know  :)There was a lot of discussion about Rowland gear on Audiogon.  Just search Audiog... 
AES/EBU cable length; CD to DAC- 1.5 m or very short?
Short cable allows to avoid reflections. The common rule is to use cable that has propagation time shorter than 1/8 of transition time one way, making it about 2ft for 25ns transition time (assuming 5ns/m propagation time). I would not go more tha...
