Post Subject: I finally measured the dac outputPosted by anthony on: 4/30/2019
...and it is a neat 1.5VRMS with zero attenuation. So with my -6dB it puts out 0.75VRMS, so not quite as bad as I thought. I will have to do some listening to try and determine whether -6dB is needed or if I can get away with less attenuation (zero would be ideal).
Last night I did the maths on the LCR phono that I intend to build and it should have 0.9V output with a balanced SUT or 1.8V output with a singled ended SUT, which equates to 73db-79dB total gain. Again, I wish there was more output but it is what it is. The balanced input is roughly the same as my attenuated dac.
Also, I've contacted Guy Hammel about a Placette line amplifier so I will see were that goes. I do not want another box so it is going to have to fit into the current linestage box if I decide to go that way. This afternoon I will order a bit more stuff to finish my diy SS pre with gain and try to get it finished as quickly as I can so that I can measure just how much voltage input I need for the DSETs in my room.
