I am a new member and this my first post. I came from Italy.
I spent many many time to setup my Tannoy Edimburg Prestige HE so I hope to help you for a good result.
1- Amplification.
The best way to drive these loudspeakers is "the passive multiamplification".
My system has also the Prestige ST200 super tweeters so I used the triamp for a total of six tube power amps driven by Klimo Merlin Reference LS1 with its tube unit to power itself.
The power amps for bass is based by 805 tubes SE class A driven with 300B. This because 805 tube has very good thight,articulate sound and it is very speed on bass response. The very important thing is that this amp shoud have the volume control. For the mids and supertweetwers, the tube amps are SE class A with 845 tube. The 845 tubes are incredible in the mids and highs audio area. The digital source is a 300 built unit in the world California Audio Labs Master Series SC Twenty Tranposrt and California Audio Labs Master Series SC Twenty Tube Analog Processor. Now all know that all Tannoy system are not plug and play, so I spent many time for the best setup for these loudspeaker. I have a great area, about 60 square meters, where they were intalled and this area is very musical and non resonant but...this not sufficient.
So I hard worked with the controls on the loudspeakers and on the tweeters and after many time spent, I tried this configuration:
a- Loudspeaker:
Treble Roll Off -2
Treble Energy - 1.5
b- Supertweeter:
Sensitivity 95db
Crossover Frequency 14kHZ
So I tested the loudspeakers and... "great very good sound".
"Now I want to test it at higher volume" I said, so I put the Klimo volume at 12 O'clock and I heard that the sound was a bit hard (we have to know that tubes of the system were selected one to one for its musical sound and the cables too). Where I can put my hands now? After many days I said myself: " Change the phase (+ to -)in the mids loudspeaker inputs". I tried the change and... "what high pushed sound".. WOW the sound was very very beautyfull in the mids and highs area. Than I pushed the Klimo at about 2 O'clock without any problems. And what dyinamic range!!! I had sweet mids, sweet highs and airy response with classic and jazz cd's.
So, what means all that? If you find a very good setup in your hifi chain these louspeakers can give you very emotional and incredible sound.
