hello!
after a couple of basic cmoys with a opa2134...at last i have the chance to get some better parts...someone on head-fi is disposed to send me some...as in my country i can't find...and i want your opinion..wanna know what to buy
my opa2134 cmoy was pretty basic except i was using 2 x 9v battery, gain of 5.7, 470mF for the power supply and 1mf input caps and r5 of 47 ohm as i used it with low impedance headphones...i liked how it sound...but want un upgrade and use it with lower voltage battery
here's what i wanna do...
i wanna keep al the settings before the gaine/the capacitors value but with a ad8397 as opamp and a buf634 and a tle2426 instead of 220k resistors shown here : but with only one 9v battery
how will it work ?...i wanna use it with low impedance headphones as audio technica m50...grados sr80...etc
or should i just use a tle2426 and a ad825(it works well with low voltages) in a basic cmoy ?
or could u sugest something else beside making other amp like pimeta/mini3 )
advanced thx
cheers
