The CTA disc was perfectly mastered sound wise and sounds great through vintage Quad equipment or my modern set-up "as is" and as it was meant to be. If I want more or less bass / treble I just turn a knob like back in the day, but I don't need to. The mastered disc's recording on CTA was thank god not "ruined" by modern "lossless wars" compression that kills the dynamic range of recordings. All of the dynamics of the original recording are here on the CTA title, mastered by one of the greats of the music industry.
The ELP "Brain Salad Surgery" and Crowded House titles are great, but we're completely different animals, those being remastered from the original master tapes into the modern age of 10 years ago in 5.1 sound. Not original "Quadraphonic" as this faithfully is. I would though recommend reissues of these DVD-A titles (as well as many others) as they are highly sought after and go for big bucks on eBay.
Although we did have a few small releases of Quad material that did come out again, this is the first title if I'm not mistaken, marketed as Quadraphonic, for "Quadraphonic" music fans. With nothing in the Center and LFE channels, as it should be, for what will hopefully be just the beginning in a very long series of Quadraphonic reissues, with many unreleased and familiar titles coming our way soon.
These are serious and extremely important releases of the highest order. For what we have waited Years and Years for and thought would never happen. Let's stay positive here and pray that all the Quad material gets released so that the original Quadraphonic Masters are saved and not lost to the ravages of time before its too late............ We will do our part and buy each and every title that comes our way.
