    Jokes

    The 6th & Final Affair Jake was dying. His wife sat at the bedside. He looked up and said weakly: 'I have something I must confess.' 'There's no need to, 'his wife replied. 'No,' he insisted, 'I want to die in peace.. I slept with your sister, your best friend, her best friend, and your mother!' 'I know,' she replied. 'Now just rest and let the poison work.'

    The 4th Affair A woman was in bed with her lover When she heard her husband Opening the front door. 'Hurry,' she said, 'stand in the corner.' She rubbed baby oil all over him, Then dusted him with talcum powder. 'Don't move until I tell you,' She said. 'Pretend you're a statue.' 'What's this?' the husband inquired As he entered the room.. 'Oh it's a statue,' she replied. 'The Smiths bought one and I liked it So I got one for us, too.' No more was said, Not even when they went to bed. Around 2 AM the husband got up, Went to the kitchen and returned With a sandwich and a beer. 'Here,' he said to the statue, 'have this. I stood like that for two days at the Smiths And nobody offered me a damned thing..'

    You're tapping a rich vein of speaker porn Knucks!

    Amplifier porn

    Each power amp weighs 220lbs, and the centre preamp 155lbs. Lighweight it is not.

    Amplifier porn

    Designed by a guy called Steve Sells. I hired Steve straight from University back in around 1990 when I was running Engineering at Wharfedale. We were planning to re-launch Leak, and I said to Steve "Design the best power amplifier you know how. Exotic components, silver wiring, multilayer boards - no problem". He designed a stunning piece of work. When I took it to the Audio show in London, and wired it to the speakers, a sound like a quiet tinny radio came out. Turned out the shorting straps were still on the back of the speakers - and Steve's amp was playing the cables into a short circuit. The sound came from the force between the cables. Took off the shorting straps and pow! Awesome. Fast forwarding several decades, and Naim likewise let him off the leash. And Statement was the result.

    What are you listening to Part the Third

    The notorious test of cartridge/arm, the pressing marked A11 is the real killer. My Zu/DL103, SMEIV (with damper) and Garrard 401 tracked it like a champ. And frightened the bejeezus out of me at the first cannon shot! This is what the grooves look like:

    matching resistors

    Looking at the TP schematic, the noise is limited by the input resistors of 2k2. The native noise of the OPA1632 is an equivalent noise resistance of 100 ohms (ignoring 1/f noise). Even so, with 2k2 input resistors the input circuit SNR should be ~ -120dBu, which is still pretty darned impressive.

    matching resistors

    Common mode rejection is critically dependent on resistor tolerance in a balanced amplifier like the OPA1632. I'd have to look it up but I think 0.1% resistors will mean a CMRR of -60dB. And at that level you need to make sure they thermally track too, and have very low voltage coefficient. All that hoohah with discrete component tolerance and CMRR is why THAT have adopted everything on a chip with laser trimmed resistors and bootstrapping to make the common mode impedance huge. The InGenius devices get to -90dB CMRR, the only real disadvantages are the pretty average SNR of -105dBu because the internal impedances are in the tens of k range and 5ppm distortion. That is where the OPA1632 with truly impressive low noise of 1.3nV/rootHz and ridiculously low harmonic distortion of 0.22ppm wins big time.

    RIP someone or another

    Doris Day - RIP. Always a joy to watch her classic movies. A long life, decidedly disastrous in her choice of men, and rather reclusive in later years. And RIP Brian Waldon, UK political journalist, MP and rottweiler interviewer. His political interviews and comment was a much watch on a Saturday morning in the 80's is he put politicians on the rack.
