I have a Music Hall Maven, and it has 5 socketed opa2604's in the circuit. The sockets are numbered 108,109,409,410,and 411.
2 are in the preamp section and 3 are in the DAC section. I'm assuming the numbers correlate. Does anyone have access to the service manual? I emailed Music Hall directly, but they said that there is no service manual for the Maven. I'd like to update the opamps, but I'm not sure which is the I-V, buffer, etc. Does anyone have any idea? Should I just replace all of them with the same opamp? I'm bringing in AD823's, OPA2132's and the new LM4562's.
Thanks,

PS I assume that this is a Shanling unit...the boards are markes SLM-120.
