I had a couple of Vector Research pieces (receiver and a VCR) that I bought during their heyday in the mid-'80s. Vector Research was a design group in the Camarillo/Westlake area of CA. The gear was outsourced to various far East mfrs, including NEC for VCRs and the mfrs that made the gear for NAD and Rotel. Read the description under Damark Industries here.
In amplification VR made a point of having higher current designs that could earn an FTC rating into 4 ohms (also similar to NAD and Rotel). I have one of their receivers (9100?) that was rated 60wpc into 8 ohms and 90 into 4. Compared to the receivers coming from Yamaha, Kenwood, and Pioneer at the time, that was significantly better current delivery. My receiver also had a switch on the back that enabled you to decouple the preamp from the power amp, and flip the amp into 200w mono mode. They also made a companion 60wpc power amp that you could switch to 200wpc mono mode. It provided an inexpensive upgrade path to take a receiver and turn it into either a biamping or 200wpc system.
As stated before, the built-in frequency synthesizer tuner was excellent.
I still have mine, but I accidentally blew the output stage by shorting the speaker leads when I thought the unit was turned off.
