Quadraphonic on 4 track tape like all types of recordings had good, and bad. I've heard some very good Quadraphonic recordings. The limitation of Quad was more at the end user/retail interface and the LP. Which has proven to be a weak surround source.
There is a reason companies invested heavily in Quad sound, there are intrinsic advantages to surround sound and how human respond to it. That research was done in the the 40's 50's.
So I would imagine that the very best Quad recordings would be satisfactory versus todays digital surround like PLII and Trifield. Computing power is beyond the imagination of people just 20 years ago let alone 40.
And this is the key to making surround a viable argument. The technology for it has matured and is available inexpensively. Digital can be edited and manipulated with very little tainting to the original information.
The key to digital is to jump in and embrace all its benefits. EQ, compression, room correction etc. Unlike analog, digital can be manipulated very effectively, because its ones and zeroes. A weakness that becomes a strength.
Now please note that digital can still be improved but the potential is being utilized and improvements are being made as computing power increases and that power becomes cheaper.
