I'm trying to figure out the topology of doing an A/B test between the Asgard and my Onkyo 805.
Right now, i have my soundcard hooked up to the 805 via SPDIF and L/R analog out. Since im comparing amps (instead of DACs), i would only use the analog outs, but I have to split/duplicate the signal so that each amp receives the same signal.
Im thinking of just using a simple RCA splitter cable duplicate the signal to each amp. Originally, i was going to use the preouts on my 805 to output to the Asgard,l but then the Asgard would be receiving a preamped signal which may taint the experiment. What do you guys recommend?
I will be using the following A/B switch which will be at the end of the chain where the headphones plug into: http://www.sescom.com/product.asp?item=SES-MP3-RCA-AB
*UPDATE* I forgot you could use the soundcards ASIO drivers to direct the L/R channels to any of the other analog outputs. I will probably route them to the surround L/R and surroundback L/R analog outs and run those to the amps for comparison. Can't use the front L/R analog outs since they use different opamps than the other outputs.
