For me, the option with NE5534A is more preferable. However, it requires an additional element, such as a capacitor to work in I/V stage. In any case, both options are not standard. I bought chips and adapters, and then I did soldering. Purchased electronic components on Ebay, mainly from the seller under the nickname HIFIIC.

@grig: Try 4 x original MUSES01 or 4 x MUSES8890.

 

Anyway, in case you're using LME49990 now, please swap them with the default LME49720 and let us know if the noise is still there when V5i are used in LPF.

i have the original muses and yes it does ! like it does with lme 49990. btw why you recommend the 8890 and not the 8920 ?

Typo, sorry. I meant 8920, of course; 8920 is a FET-input opamp designed to be used in I/V stage and it really does a good job.

You should use official channels, you'll definitely find 8920 ad 8820 too. eBay can not be trusted, sorry.

On Ebay there are sellers whose reputation earned the consumer's trust. For example, for the purchase of Muses 01/02 and 8920 can turn to gyrocom (Audiotrak).

gyrocom looks like someone that can be trusted to be honest
