Here’s a great article on the early cable designers. MIT was one of the first and set the stage for super high end cables. https://www.theabsolutesound.com/articles/cable-designer-roundtable/ In a niche that relies on promotion and subjective impressions, Transparent, the one time distributor...

I like their stuff. Made an improvement in my system to the point that I opened my wallet. That’s a rare occurrence for me in cable-land. Sorry to see them go.

Feanor, the history of your amplifier design is very interesting. You can read about it here: https://www.stereophile.com/content/diy-chronicles-part-one It started as a DIY project and ended up the genesis of the Dartzeel brand. It is informed by work done by Nelson Pass and Matti Otalla. It...

For me, the primary value of this forum is sharing personal experiences with music and gear. AI is not helpful in this context. A secondary value is exchanging technical information. AI can be useful in this context. However, you often get regurgitated content from prolific web authors having...

It’s unusual you have 3 phase into your house. All power distribution in the US is three phase and transformers on the pole or the street tap off two of the three phase legs and step down to the 120/240V split phase service in most residential properties. Good news if the transformer is all...

Wow, a service focused on multichannel source material. Auro 3D is a niche for sure. It will be fun trying this out when I get the new theater build complete as the Trinnov processor will map my surround setup to Auro 3D and multichannel PCM. Not much here for 2 channel listeners.

Electrically there is a lot going on in the speaker/amplifier interface. Most loudspeakers are non-linear loads for an amplifier. Meaning that it may take more power to create positive SPL than negative SPL, or vice versa. Loudspeaker crossover components store and release energy in electric...

Sometimes sarcasm is incorrectly interpreted. Just like CharGPT gets many things wrong.

A big thanks to Ralph who in several previous posts articulated why amplifiers sound the way they do, and how measurements play a key role in understanding how things sound, and why some people may prefer a little 2nd harmonic distortion with their fries. I’ve stated here before that I can’t...

It’s the same reason I’m using a German ISCO Panamorphic lens on my new theater. By any technical measure it can’t improve the image but subjectively it does. It’s got that certain Zeiss Schneider look.

I’ve been intrigued by many posts here that compare the perceptual characteristics of the technologies we use to enjoy recorded music. Tubes, Solid State, Class A DHT, Class AB, Class D, vinyl, R2R, digital in its many forms. The list goes on. The arguments regarding the fidelity of different...

They have picked some great titles. Having sold my A80 a decade ago I’m not sure I want to hop on the R2R bandwagon again. It’s great to see a growing interest in these excellent analog formats.

Michael is right. Audio flat-earthers don’t favor powered speakers, DSP or not, because they eliminate several variables and choices in system setup. No need to try and match amps and speaker cables to the speakers. No chance to spend $10k on wire between amps and speakers. No chance to spend...
