Don't forget Rupert Neve and John LaGrou.

I'm pretty sure that more than 50% of the rock recordings in our history are through Neve circuit, and also more than 50% of the classical recordings post 90's are recorded through Millenia Media.

I'm not aware of any power amplifier made by Rupert Neve itself. or its company...He's definitely the best in the mixing recording gear industry, but we could consider him a genious when talking about amplifier circuits theory in general and mostly in small signal amplifiers in particular .
At the same time youmade me think about the Mackie 1400VLZ and M1400 amp , but i don't know their designers...

Both of them are sadly no longer with us, unfortunately.


Also, I would argue that the Marinair LO1166 output transformer that is largely responsible for the sound of the Neve 1073 microphone preamp is perhaps the single most influential transformer ever designed. Even though few studios still use a Neve 80xx series console, thousands of them use Neve 1073 preamps, either original or clones. It's truly amazing just how many influential recordings have passed through that circuit.

Something "off topic" but might be interesting. I've worked on the famous Neve 1073 mic preamp (clone) some years ago and know the circuit well, lot of tantal caps in the signal path, input and output transformer etc. Distortion is fairly low, about 0.05% but dominant harmonics are 3rd and 5th and you can clearly hear that it sounds like "effect box". The similar story is almost about every famous studio gear piece, it's about it's own sound, not the fidelity.

The distortion in the 1073 rises at lower frequencies IIRC. Much of this is because they are running 80 mA of DC through a gapped output transformer.

There are many good, but for me Nelson Pass is the master in solid state transistor amps, from his work at Treshold to his actual work at Pass labs and First Watt. From those i heard these stand out above the competition. Jean Hiraga is also very good, and the only one that comes near Nelson Pass for me.

Bruno Putseys (Hypex NCore/Purifi) is the one that makes Class D (also solid state) amps that i actually can stand (and i'm a class D hater say many) for hifi.

Yes, but nothing drastic if transformer is good.. as I said, it's an "effect box" with all sorts of nonlinear parts in the signal path, I'm just puzzled why people like the sound of odd harmonics... Maybe easily just a marketing driven vintage gear myth...

Or maybe not.Tape has H3 and H3 only...i like tape and lots of other guys like tape...The transformers are doing the real miracle.Just read Eric K Pritchard patents and you'll understand why!
