Does this fix the ESS Hump

[tsangyoujun]

No. The ESS hump needs to be fixed in a hardware update.

Is a balanced version coming soon, maybe the RCA jacks are also causing issues

[tsangyoujun]

Hi @DSBAudio, we’re working on an extension board that will provide balanced output. v1.04 firmware is unrelated to the RCA jacks.

[DSBAudio]

Will the extension be compatible with vim2 and will there be a balanced version only. Or will it be just a add on with balanced output

[tsangyoujun]

I don’t have exact specifics at the moment as its still in development; could change later.

Likely will be an “add-on to the Tone Board”, as we would prefer not to change the existing board layout - it works well as it is.
