Until now, I thought Astell & Kern players were expensive & blingy. Silly me!

Unless you're Fonzie!

I see, each tone produced by a different speaker. That sounds legit.

Note: I have shown in my system that my speakers have lower distortion than the UMIK-1 measuring mic. When I measure distortion using Rode NT-1A mics, I get lower measured distortion than I get when using the UMIK-1. That's with all else equal: mic position, system volume / loudness, etc...

The method is either incorrect, or I don't understand it. First you played single tones at 60 Hz and 1300 Hz, respectively. Then you played both tones simultaneously, and intermodulation products appeared in the results. You conclude that the intermodulation came from the mic, but how do you...

What I like about that EQ is the bands are set at perceptually equal intervals (1 octave spacing).

When I was a teenager my best friend's dad had one of those. We spent many hours listening to it. Seeing it again after all those years really brought back some memories!

IME, none of the cassette tape style demagnetizers work. Even a fresh battery doesn't seem to provide enough power to create a strong enough field to really demagnetize the head. I've had much better results with the wand-style demagnetizer that you plug into the wall. I've confirmed this by...

The nice thing about blending your own is you can always adjust the formula. PS: I used up to 35% alcohol in my Nitty Gritty 2.5 FI, which has a 10 amp vacuum. Never had a fire. Yes there were fumes, you could smell it. Later I reduced the alcohol to 18% because the higher concentration damaged...

I realize you weren't asking me, but this might be helpful. Summary: 1 part 70% isopropyl alcohol 3 parts distilled water 1 drop of pure (no perfumes or other additives) liquid soap 1 part iso to 3 parts water is: (.7A + 0.3W) + 3W = .7A + 3.3W, which is .7 / 4 = 18% alcohol IME, that's enough...

Good advice. Back when I had vinyl and a good record cleaner... I found it was VERY important to clean a record before first play. When I bought used records, the record cleaner definitely helped, but how much it helped varied quite a bit. My working theory was that when you play a record when...

For many years I used a Nitty Gritty 2.5 FI to clean my records. It worked great getting them spanky-clean. When I finally got rid of all my vinyl I sold it to a friend, and it's still in service. I bought it back in the mid 90s so it's definitely a durable quality product.

I learned about Shannon at university, getting my math degree. Not until 3rd or 4th year though, in group/ring theory when we got into public key encryption and took a brief detour into information theory. James Gleick wrote a great book about this topic, which includes Shannon and others: The...

At the risk of adding to an old thread... My LCD-2 Fazors came with an individual measured curve that looks much like yours. It's a bit misleading since it's done against diffuse while we're more accustomed to seeing Harman. The Harman curve has too much bass and treble for my taste, like a...

Yep, that's it. If you didn't hear any difference the first time around, I'd say that's a good working definition of "subtle". This timing/buffering is inherent to SPDIF interfaces, because data delivery is controlled by the upstream device, so the downstream device has to adapt to it...
