In this scenario having carefully matched tubes would, I imagine, be ultra critical for ultimate performance. Having a single tube drift out of compliance would impact the the entire channel, and matching 16 (32) would require sorting through a very large sample set. Much easier to match up a quad than a sixteenplet.

Not sure about REF750 but at least in VT200mkII matched quads are required. Tubes are being biased in groups of four, it's not necessary to match all 16.
