Need advice replacing my preamp

@verdantaudio Im all ears on suggestions please share. and Big_Greg true just because there are XLR connectors on the back panel you have to ask if it is truly balanced. @Tweak1 I would have to change out the amp too but one at a time. Right now just focusing on one component :)

@Joey54 I am using Transparent Audio cables 20ft long. I just purchased some XLR cables (mogami wire and nuetrik connectors) I am told by a Pro Audio company that XLR by their nature of construction are better at noise rejection than single ended RCA. I am waiting on a XLR to RCA adapter. I am told it may help. I did speak with Dan and he agreed to start there.

@Atmasphere thank you for the explanation. I agree with you. Lets see how the cables work. BTW if I connect the output of my DAC it is quiet. I get the noise with out even turning the preamp on!

@atmasphere  I agree, I am trying to rule out the cables first. BTW I should have clarified that I would like to go Solid State and fully balanced over time. The idea is as I am getting older I dont want to futz with tubes and noise issues so I want to position myself with equipment that will give me that reliability and low noise. Thanks.

OK so I changed out the cables, no difference. I found a lighting dimmer that adds some buzz but still need to get rid of more noise.

OK, so today I did play with the RCA and notice it is micro phonic. I guess I have to move to a balanced set up? or place my equipment rack on the wall between the speakers thereby shortening the cable to 1.5 meter.
