Re: Test Equipment Anonymous (TEA): Discussion and Group Therapy thread Part 2

This is a true and faithful account of my involvement with tggzzz's acquisiitions at W-s-M. Here, we have a micro-payment service for cellulars that even the old hams and their widows have learnt to use. I never carry cash except when I need to go to the punk club that does all in cash. "Swish...

Re: Test Equipment Anonymous (TEA): Discussion and Group Therapy thread Part 2

The current trend in the post-S.A.W music factory is indeed to approach a 0dB crest factor. One has to be more eclectic in ones search of music rather than just condemn society based on the lowest common denominator. As a natural consequence of being an Einstürzende Neubauten fan, I these days liste...

Re: Test Equipment Anonymous (TEA): Discussion and Group Therapy thread Part 2

With hi-fi they were talking about tangible things, such as performance measurements, until around the mid 80s. After then, I agree with tggzzz, it became like reading reviews of wine. "This amplifier has a firm but not strident bass, some loss of control in the mid-range, the treble is fright...

I used to keep a six D cell Maglite by the bed, but the batteries failed, swelled, and couldn't be got out... When it comes to lies, its seems torches are even more creative than 1970s amplifiers with their music power, peak power, and Sinclair watts. But I have to admit that my little 3W LED torch...

"Professional" video equipment generally meant "Not up to Broadcast standards" when I was in TV Broadcasting!
Sony monitors with "P" in the type name were cheap.

Those with "B" were not.

And another; this is Alberto Giacomettis vision of a cat. There is something to it. The sass. From Fondation Maeght just west of Nice in the hills above Côte d'Azur.
