It wasn't lost on me :-D
And then I have to ask, why is it always replace a cheap op amp with a 26, never try and get the most (or in fact, the least) out of a op amp first, maybe spend more than £5.
It's a fair point. I have SuperRegs to try. But without trying the 26 how do I know how it compares to an op amp with adequate or better power supply.

You don't, but that wasn't suggested as a option :-)

Not explicitly no, but for brevity as much as anything :lol:

I would suggest cutting to the chase and trying LME49720. Still available in PDIP and properly decoupled (C0G and Film) I would bet my own money you couldn't hear it.

Again, add triode to flavor, at least that's in effect what I was doing with the system you heard at the show last month. Valve phono stage, everything else gets out the way (passive transformer preamp, 100W amplifier with about 0.0005% THD driving 98dB/W speakers).

I've continued this on the MoFo thread, so I can find it again in the future and not to derail Paul's thread any further.

Quite excited for this one.
If something looks too good to be true, its probably due to a mistake. I gave up looking for a magic undiscovered solution some years ago, its not going to happen. My answers to the question in the topic thread are:

1. Get new speakers
or
2. Use £50 solid state amp from ebay. if you want distortion, add a triode somewhere.
or
3. Build a MoFo. if you want more distortion, add a triode somewhere.
:lol:

Turns out they are connected for 10 K ohm into 4 Ohm.

So that is great!

Well that puts the GM70 SE next on the list.

Something like this.
