[QUOTE="VALVAGLO, post: 587200, member: 1099"] @ Jozua the best most modern valve amps still follow the pattern or topology of the "Williamson" valve amp designed just after I was born. The exceptions to the williamson design are Quad 11. Mac 275 and of course the Mac which Francois now owns Mac 60 ,the Futterman OTL ,the Graaf range of OTL's and of course, the Audio Research valve amps. There are many more but they also follow a very old feedback system, which gives them their unique sound. The big difference is in the way that the signal is fed through the output transformer. Each company has a new name for this feedback topology, but as I mentioned earlier ,Peter Walker of Quad, used this system in 1947 or earlier I think. Which proves what the Bible says in Ecclesiastes, "There is nothing new under the sun" My interpretation is that its always been there but we only now are discovering these amazing things. Regards.
