There are 6 sets of boards lefr from the GB (1set = 2 IPS6 and 2 IPS7)
If anyone is intressted.
IPS6 and IPS7 ( for M2x)

Bi Amp with M2x
I am curious if anyone has bi amped their speaker system with the M2x. What are your thoughts? What did it do for you?
Or, perhaps the 6x24 xover NP designed. Not sure I really understand what the sonic differences would be. They certainly function differently.
Thanks,
Don

Can you expound on what you are asking about? What does the M2x have to do with Biamping aside it’s an amplifier?
The 6-24 is an active crossover designed really to be used in lieu of a speaker level crossover...

could the M2 use the same bias system as the F4 with a TL431 (or low current version of 431) ?
this could allow to remove the source resistors and increase the square low

You might get more opinions if you posted on the M2 thread created by Nelson Pass in 2015.

I just learned there is a mistake in the IPS7 parts list attached to the post #3408:
Mouser part for the sockets indicated in the list is 110-87-304-41-001101, but this has 4 pins in total, not 8. The correct part should be 437-110-87-308-41-001101.
Had to learn it the hard way - looking at the part in the pack from Mouser. IPS7 for my M2X will have to be delayed until I get the right ones 🙁

Thanks for catching that. The wrong part number was on my soon to be ordered BOM.

I think you can stack, one next to the other, the 4 pin parts to get the same thing? Or am I missing something?
Yes, you could put the 2 side by side I imagine (not sure), but you would need twice as many.
I think you will like the IPS7, especially with LME49720. I tried OPA1234 and was very happy also.
IPS6 - the start
Hello,
today I played the 'matching' game. 4 nicely matching J113. Matched the output BJTs (PNP-NPN) and from Left-channel to Right_channel.....🙄
And slingin' the hot iron around beautiful legs.... 😉

I put some OPA134 chips into 6L6's IPS7 boards and he has never changed them since. He thinks they sound wonderful.

OPA134PA
Yes, I fully agree! The OPA134PA is an 'older' OPAmp, single channel, Fet at the input and still sounding good. Especially at his low price! And it can handle up to 36V (+-18V).
I used the OPA134PA in a few projects. In one of my active crossovers for example.
I will try it, when I have stuffed the IPS7 boards....
