Here is the email that I sent, and their answer. I am aware of Jon Soderberg, and the great feedback that people give him, but here is another option. When you think of what you get as a final unit, compared to what's out there at similar prices of vintage + updates, these are GREAT DEALS!
Hi!
I have the following vintage Threshold equipment:
Power amps:
S-200
S-300 (two of them)
S-300 with the “e” mod (to 350-e)
S-450e
Line level:
Fet-10e line level preamp
Fet-10e cartridge gain preamp, (phono preamp)
Dac-1e Dac
Please tell me what upgrades that you can perform on them. I am open to any options that you have. In particular, I was wondering if you can install balanced inputs on the S-200 and the S-300 power amps. Any advice that you have, I would appreciate very much.
Hello Dave,
Thank you for your inquiry. We do not install balanced inputs on the
S/200 and S/300 power amps. On the models you have, we would replace
the power supply capacitors, rectifiers, rebuild the FEB (front-end),
replace worn down items such as the power switch, RCA jacks, fuse
holders, etc. BIAS level is adjusted to proper specifications.
On both FET-10e models, the external power supply capacitors, internal
electrolytic capacitors, and power circuit relay are replaced. In
addition, the volume control pot is replaced on the line-level preamp as
well, a normal maintenance item.
At this time, we do not have any upgrades on the DAC 1e.
To service these models, you are looking at:
S/200 - $700
S/300 - $750
S/450e - $850
FET-10e line-level - $600
FET-10e phono - $500
If you have any further questions, please let us know.
