For anyone interested in what makes the new Quad tick compared to the old here is a breakdown of the differences as we see them.
There is a fairly good deal of difference in the way these spaekers sound compared to the original 63's and the later 63 USA monitor. First The construction quality is not at all the same as they have used a much cheaper plastic to contain the electronics than in the 63's. All the electronics are now contained on a single circuit board of a lower quality creating several problems. If you have a problem with protection it requires a new board ,if it's delay lines,a new board ,if it's power supply ,a new board.This certainly will cause a higher cost to the customer after the warrenty period if work is needed. Along with the lessor expensive parts come some distinct differences in tonality. We still sell after market speakers certified with full warrenty form the 57's to the latest 63's and find a more desirable balance over the new models. In my opinion ,and I've sold the speaker for 20+ years and have used hundreds of different components ,the new speaker offers some advantage in volume but never in the area for which they became famous ,long term listenability.As for the realibility we are in close contact with many people who are intimate with these speakers and issues still exist with realibility.. In one of my home systems there sit's a pair of 30 year old 57's and there great. I think better than any of the products produced since, but I certainly recommend auditioning more modern designs be they one's I carry or any other qualified dealer before purchasing the newer speakers. There are many that will produce a higher level of detail, sheer dynamics, better listenability and will not fall apart under maximum listen conditions.
