We all used to think a new vinyl record sounded good. A look at the ASR Phono Cartridge Measurement Library database shows that state-of-the-art phono setup has about 0.3% THD best case. Frequency response can be pretty good, certainly to 10KHz or so. - But the overall Signal to Noise ratio...

125 proof ! ?

Anything with banjo. Especially annoying: banjo in Jazz. Also not a big fan of sax.

Check out SOMAFM streaming channel "Boot Liquor". All the songs mention booze somehow. (and/or broken hearts, momma, and cheat'n) Very humorous and great music.

I like the feedback answer, but more accurately what we need is high open loop gain in the pass band, like 100db. It's also nice to minimize distortion as much as possible in the topology of the circuit, by proper design and layout. D. Self And R. Cordell have both written great books that...

The Aphex exciter was invented when Kurt Knoppel (sp?) miswired a Dynaco St70 by accident and generated huge 2nd harmonic distortion. He liked what he heard and made a business around it.

12 bit perfectly dithered 50k Samples/sec sounds better than state-of-the art analog tape IMHO. Much better (perfect) time-base and perfect frequency response. Both things are very hard to get right on analog tape. Noise is about the same. Some hiss. So what, really. Now we have dead...

KEF is the way to go. Just get something like this: https://www.usaudiomart.com/details/649907093-kef-r600c-center-channel-in-rosewood-mint/

I think we can all agree - this whole stylus - soft vinyl groove thing is a disaster. I am so happy I have Roon, Chromecast, and a good DAC. (and I have a SP-10 with a V15-MR Jico, - which is never used.)

Back when we made test tones for the 3M Digital Mastering System, we would make a EPROM with the sine wave in it. We would try to make each sin different so eventually we would test nearly all the numbers in 16 bits. For example, if we had a 16K Byte (16384) EPROM and we wanted about 1K Hz at...

Just try to not like 'Boot Liquor', on Soma FM. It will change your mind.

Well, if you analyze a C-2 preamplifier you will see the tone control section is extremely poorly designed, almost criminally so. I had to bypass it entirely when I did a recap and opamp roll - I installed a Doug Self tone control - and it was perfect. I doubt Carver had any hand in this...

Agreed. Watched this at my university's film society. It's great and at least 40hrs long.

I bought them. I tried all the tips and none worked (both ears). I guess I need a custom molded fit. Sent them back. Damn.

It's true. Well dithered 12bit can sound darn good. It's technically on par with analog tape and even better re wow and flutter. It's just a wee bit noisy. I heard this demonstrated by Stan Lipshitz, or was it J. Vanderkooy?
