I am a retired university professor (nothing to to do with electronics, audio etc) enjoying picking up a soldering iron again after over forty years. My current system is a Naim DAC, and NAC/NAM 152 going in to a pair of Beauhorns with Lowther drivers in a very large listening space (about 10m x4m x 8m). That creates a slightly toppy sound as there is a lot more glass and walls than soft furnishing, and a bare wooden floor, but I'm not complaining. I listen to all sorts - mostly classical, especially opera, but also folk, rock, jazz... anything.
I enjoy picking up old audio stuff at auctions and repairing/reconditioning it. I recently managed to get hold of two pairs of Quad 57s, both 1969/70 vintage. I wasn't expecting much as they came without leads, only one pair still had legs and even then only five of them. However they were both covered in so much dust that I hoped they might still be OK. I lucked out. After a thorough clean they looked fine, no arcing damage and dust covers all in one piece. They were a wee bit quiet but the volts on the EHT blocks didn't look too bad. I've since rebuilt the rectifier boards, which has pepped them up a bit. Running them as a stacked pair definitely improves them. I think my space is just too big for a single pair to be comfortable. However, even in my large space there is not enough room for the both the Beauhorns (about 1.4m x.4m x .9m) and stacked quads, so the latter are going to hang from the ceiling.
I know positioning is going to be critical, so I want to be able to move them around (at least until I know exactly where they are going to go). That means keeping the weight down. I've replaced the front and rear grills with a lighter and sonically more transparent but still electrically grounded mesh. By far the heaviest components are the four audio transformers. I fancy moving them to the wall nearest where the speakers will hang. However I wonder about the impact of having bass panel bias voltages of 6K, along with treble panel voltages of one quarter of that, travelling for about a metre. My school physics tells me it shouldn't be a problem as long as I use high voltage cable of the kind used for test probes. But will longer cable lengths mess anything else up, such as the crossover or relative volume of the panels?
Any advice very gratefully received.
