Preamp choices:Short list

@russ69 , I currently have a 20 ft RCA and get noise. I'd like to get to a fully balanced system. My DAC and mu phonostage are balanced as well

@soix  I am currently using a Modwright LS100 (with all NOS tubes) and Wells Audio Inamorata. I like the sound of a tube pre. I have not found solid state to have the fullness in the lower mids. I have tried some solid state but they tend to sound thin. But the bass in SS is better. The Wells is a SS amp that has "tube like" qualities. Sonically they sound good but I am getting noise. Now here is the kicker: I am getting older and want simplicity and reliability in my system. I don't want to be screwing around with tubes and chasing down issues. Also I can't lift 75lb amps any more. So I am in a quandary, I like a certain sound but may not achieve it the way I am going. My first preference based on this is a SS Pre and Class D amp. If I can't do that it's a tube pre with Class D amp. My speakers are 92db efficient I run 2 GR Research subs driven by Rythmik amps. I hope I covered everything. Thank you for taking the time to consider. (BTW, @yyzsantabarbara suggested Benchmark, the only reason I am not jumping on their pre is I am afraid of it being analytical sounding and far from tubes. They do have a trial so there is no risk.

@mazian what is wrong with balanced, in what way would SE be better?

@atmasphere I played lots of abusive sports for many years. Im not young and have had 5 orthopedic surgeries in the last 7 years (that includes one back surgery) That should be pretty clear that I can not be doing heavy lifting. I am also planning years our as I hope to have the next set of equipment into my 70's. I have 25 ft mogami that I plan to use going forward. I think were are basically in agreement.
