Audio research ls5 question

Was there a ls5 mkIII with remote and rca plug model stock from the company ever manufactured ????
At the audio research retailer in my area a salesman told me once, that there was a model made like this few years back but never got one in store.
Myself, never find one with rca for sale here on Agon.
So I am woundering if this model ever was produced.
no they are fully balanced designs only.
Also, the LS 5 MKll is a much better pre amp than the MKlll, IMO. You can get adapters from Cardas in order to use RCA cables with the LS 5 models.
