CD Transports a relic or a good option? Aune/AN
DVD players have inherent ability of decoding MP3 but play standard CD as it is - without compression. They offer pretty good tracking but got bad rap for sound because their analog output stage was often pretty bad.Digital cables can add substant... 
Computer vs CD/SACD discs
AFAIK every computer buffers data in RAM before playback since music is stored on hard disk without timing as data and timing has to be always recreated. Hard disk has hefty cache buffer to start with. At the end everything comes to quality of fin... 
Another CD-Player vs. PC question:
Czarivey, good observation. Early CD were often recorded from not properly corrected tapes and digitized with jittery A/D clocks. This type of recorded jitter cannot be suppressed and the only way out is to digitize again, assuming that analog tap... 
Should you tune room to headphones
Mapman, Sound from each speaker comes to opposite ear with some delay creating image in front instead of the image in the center of the head. Some headphones have acoustic feedback from one cup to another but it can be also done by creating analog... 
Another CD-Player vs. PC question:
Most of CDP play in real time. They have ability to error correct small amount of unreadable sectors or interpolate larger gaps but at one point they will start skipping. Computer CDP is under control of computer program used for playback. This pr... 
Small room....treating 1st reflection points

Small room....treating 1st reflection points
Tom6897, Look at the link I posted. Table shows sound absorption vs frequency. I was mostly interested in taming slap echo and mid-bass frequencies. These panels are glass rigid foam. I've read that organic foam has non-linear characteristic (of a... 
Small room....treating 1st reflection points
It depends on frequency range. I bought 2" thick double density fiberglass foam panels - Johns Manville 817 (not installed yet). Sound absorption table shows good absorption at 250Hz dropping to 0.38 at 125Hz. For the lower frequencies 4" might be... 
Classe CDP-10 - Trouble reading some CD's
Dirty laser? I cleaned one in my MacMini few times using cleaning CD, but recently it refused to recognize CDs even after cleaning. I open the case and cleaned leaser gently using cotton Q-tip and Isopropyl alcohol. After that everything works fin... 
Computer vs CD/SACD discs
I also think CDs ripped to lossless files on FLAC can sound better than the original CD, my theory being the error correction while ripping produces a more stable file (but don't have a shred of engineering background to prove this).Austinbob, Mos... 
What does a Hexfred do?
Rectifier conducts until amplitude of AC voltage is lower than capacitor voltage (just after peak of the sinewave). At this point diode is reverse polarized and diode current drops to zero. Unfortunately it will conduct for a moment in opposite di... 
Why not magnetic tapes in stead of vinyl records?
Ralph, I agree. I was thinking of my air conditioned basement while others have finished attic. Humidity is perhaps the worst followed by temperature changes. 
Help fixing Receptacle
It is not simple - It LOOKS simple. Get licensed electrician. I was zapped couple of times by 220V and have to warn you that it is much, much worse than 120V. Don't take unnecessary risk. There are certain areas where saving money is not very wise. 
Why not magnetic tapes in stead of vinyl records?
As I said before - attic is possibly the worst place for storage of tapes with excessive temperatures, big temperature swings between day and night and uncontrolled humidity. I would rather store them in my basement that has pretty much the same t... 
Why not magnetic tapes in stead of vinyl records?
I guess baking and storage are different things since recommendation from National Technology Alliance states: "Storage at high temperatures ( > 74° F; > 23° C) increases tape pack tightness. This results in distortion of the tape backing an...
