It's way more multi-binary. Who sits in one place listening in a maschine shop???
I agree! Just messing around 
Any high quality el cheapo digi Xo to start with, discounting MiniDSP?
Hope all is well btw. I am testing some cheapoquicko OB’s at the moment.
I got the iron boards now. To lazy to start, so instead I am spamming Mighty’s thread

So 60's....
'18' pr speakers need amps. Orgel Pipes move much air!
naah
my 15" happy with my amps, my amps happy with my 15" xovers

Hi ZM,
Apologies if already answered before, cant find it; what is the Zout of the Iron Pre SE 6db and 12 db with no volume pot attached?
Thanks. nash

Buffer Rout * voltage gain^2
for +6db (2V/V) , Buffer Rout *4
for +12db (4V/V) , Buffer Rout *16
for +6db (2V/V) , Buffer Rout *4

Rout of JFet complementary buffer is:
[1/xconductance of N channel JFet + Rsource] in parallel with [1/xconductance of P channel JFet + Rsource]
xconductance of N is (by the book, close enough for ruleofthumbingwork) 22mS
xconductance of P is (by the book, close enough for ruleofthumbingwork) 22mS
Rsource is shared, 20R trimpot, so
[1/22mS + 10R] // [1/22mS + 10R]
= [46R +10R] // [46R +10R]
= 28R
anyhow, it goes 112R for +6db, and 448R for +12db
in real life, you need decent JFet specimens to be in 22mS area, same as driving them near Idss as possible, so ........ even if you take all in account, ending 50% above shown calculus, you're good enough for most purposes
all in all, much lesser level of bulldrek than usually taken as necessary for Pure Audio Bliss
see, Pa is bombarding of recently with switching JFets, powered by plastic bricks, and everyone is peeing Tungoil from pure happiness ........ we finally have a situation (or we had it, now just amplified) that people are actually using ears, instead of reading periodicals and audiophool forums
(all that, just as excuse to post again my fave illustration )

I'm suggestible, so I got up & put Made in Japan on my turntable when I saw this. I listen from a room away and it's wonderfully clear.
I haven't taken my Iron Pre + Emerald phono stage out of my system since I built it.
May I lower R3/4 combo to approx 3ohm for additional CCS to power NP 6-24 crossover from the pos rail.? It requires 120mA and if I keep spare CCS to the 80mA I create no more heat in M1. Is the rest of the circuit happy with that?!

Edit: and of course XO parts. Though, as is, my 3134 Tannoys kick *** with just a moderate EQ bass boost, and is a simpler solution. Plus the solution is temporary, so why complicate things.
I know, I was thinking more plug and play. But perhaps, a P2P B1R2 x2 with individual pots will do it.
