Difference: Cary SLI80 Signature vs non-signature?

what Cary sells now & has for some time is the signature version. the non-signature version did not have 4/8 ohm switches, triode/ultralinear switches or headphone output & also had a chrome deck. this info is from an old thread on audioasylum I read years ago. you may want to email or call Cary to confirm.

...also non-sig. did not have a remote or preamp output jack.

my pleasure richard, fyi...you can look at owners manuals for past & present products on Carys' website under 'customer service' then 'owners manuals'. apparently there have been 3 versions of the sli-80 as per this info. enjoy, it's a great little amp for the right speakers.
