Hi Gang. Great to see some vintage Tannoy users on this forum. Rdr... nice post and well said. I concurr with futterman here regarding and the OTL amplification marriage,however there are many amplifiers that work well with the big tannoys...both tubed and solid state.In actual fact...it's difficult to make the Westminsters sound poor with any decent amplification.I preferr tubes with mine but have heard buddies 70 watt Pass amp [not sure of model] and was very impressed as it does have a nice tight grip on the big woofer.Solid State? My vintage class A 25 watt bedini does make real magic with the tannoy. I used to have a pair of original 25 watt Mark Levinson ML-2 monos. They were far and away the best ss amplification I have used in my rig. That thickness thing in the midbass/upperbass area mentioned above can be completely eliminated with a good solid state amplifier as well as most any of the OTL amps out there. However... there is a better way and a must for the big 15 inch tannoy users that preferr vacuum tubed amplification.Simply remove the crossover from the cabinet and that thick dense colour completely disappears! My pair of Westminsters were factory wired with Van den hul cable... I removed the crossover boards and rewired[with the same van denhul wire] from the crossover taps directly to the 8 omp tap of the amplifier. This little mod is a revelation and not suttle either!It also allows one to bi-amp if you preferr a different amp on the tweeter.It also eliminates the binding posts and speaker wire per se. I have used small set amps from the 3.5 watt 2a3 based wright monos,300b based amps as well as the big 60 watt parrallel 845 set monos from Antique Sound Lab and all of them exhibit a cleaner textured bass resolution with the crossover out of the cabinet. Some food for thought?
