Modify Threshold SA/2, or buy a Pass Labs X250.5?

Dear Audiogoners,
Currently I have a pair of Threshold SA/2 monoblocks, considering either sending them to Jon Soderberg to modify, or buying a Pass Labs X250.5. Will the sound improve significantly if I replace SA/2 with X250.5? or I should have my SA/2 to modify? I prefer lower noise floor in my system and with more balanced sound. In addition, my source is CDSD with DAC6e combo, will the sound imporve a lot if I connect them with balanced cable instead of interconnect?
please give me some suggection, thank you!

Hi Jpainter236,

That's what Jon suggested for the modification:

Installing Cardas Binding posts, new main caps and IXYS fast recovery diode rectifiers.

Do you have any better suggestion for the modification? also, if I ask him to add the balanced input, will the monoblocks have better sound?

thanks!
