Happy next year already Ricardo.. Siau, "A Radical Approach to Audio Power Amplification" http://benchmarkmedia.com/blogs/news/14680625-the-ahb2-a-radical-approach-to-audio-power-amplification The really radical part of this design and one which will give it a distinct advantage in DBLTs i...

Please don't make me read it closely.. from a quick pass it seems like an collection of popular buzz words-concepts cobbled together with some rather dubious claims thrown in (like large reservoir caps are bad :lol: :lol: ). I give them an A for marketing effort. About the design I'd have to see a s...

I was reading about Benchmark's new power amp and found this statement: Low Gain – The AHB2 has a low gain setting that optimizes the gain structure of professional monitoring systems. Maximum rated output is reached at an input signal level of 22 dBu. This places the upstream equipment in an ideal...

FWIW my last patent while I was working at Peavey was for a heat sink design (6,515,859 Roberts , et al. February 4, 2003). In a forced air cooled heat sink a design concern is equalizing the temperature across the heat sink from the cold air to hot air end. The amp is only as strong as it's hottes...

If I had something to water I could use the several gallons a day of brine... No longer enough to reliably flush my toilet with. I probably have standing water in my back rain ditch right now, I live on low ground and it rains in MS, so most of my landscaping effort it so insure the rain water leave...

FWIW I had customers of my P-10 kit back in the early '80s tell me they were using them as flat gain stages in front of the stand alone de-clickers sold back then.Then they returned to apply the RIAA after the impulse NR. So not a new concept, but surely made better by digital technology.

Interesting stuff... nice I was aware that Phillips messed around with motional transducers on woofers beck in the '70s but not that Matshusita predated that early attempt. Later Danley made a woofer driven by a servo motor so arbitrarily precise, but even he abandoned that technology for recent des...

Sorry I did not mean that as a personal attack, I was making a general statement about markets a few decades ago. I have designed multiple phono preamps (as well as recording consoles) so I am looking at this from an empirical "what the technology can do" perspective. Digital media is unqu...

Is your meter an odometer type with a sweep hand or is it like an electric meter? Reading an "electric meter style" set of hands from left to right is a rookie mistake your water reader may have made. The meter is odometer style so hard to misread. It's a new meter, the town replaced my o...
