Strangely Perfect

I’ve been (and still am!) busy over the last few months moving house and otherwise making a new life for myself.  Despite this, I did find time to go a see an event that I never thought would happen – James Williamson & Iggy Pop playing on stage together- for the first time in 30 [...]

Paul. This scan is from my old ETI Circuits #2 from the 70′s.  It’s about the best op-amp info you are likely to find.  With a bit of knowledge, these six circuits are an instant ready-reckoner and allow you to do almost anything!

Thanks Paul. I made a headphone amp for a few quid. It was capable of driving up to 10 headphones for the studio monitoring and was short-circuit-proof as well. I thought I’ve still got the circuit; I’ll scan it for you: Rees

The word on the street is you need a decent headphone amp to get the best out of the 990. As of mine they are open back, so its a lot better for longer use. I have a pair of beyerdynamic DT250s which are very accurate, but they are closed and not too comfortable for [...]

Hi. I’m looking to mix with these which have a nominal freq respponse 5Hz – 35kHz and weigh 270g and block out all sound. They should be good. I like Beyer. I used to use a Beyer M501 ribbon mike by them which could pick up flies sniffing with a cold and was hypercardiod to [...]
