I can't speak for the Tannoy but certainly can for the Volti. I see @charles007100 visited a local Volti owner and had a great experience, I am driving my Volti Razz with a First Watt F8 and have the Modwright LS99. tube preamp as part of the lineup. The pairing is superb. Do yourself a favor and contact Greg. He is engaging to talk with and a craftsman. I have also done the Pilgrimage to Baxter and spent a night on the shop floor camp cot - very comfortable. I listened to my Razz in Gregg's living room and we boxed them up and I left the next morning after an espresso with Gregg. Learned quite a bit as to speaker building and quality.
Tannoy or Volti
I have a friend who has the Tannoy Prestige GRF 90 for sale he is moving out of the country for half price, he paid $29000 in around 2020 not made in China. I am upgrading my Forte IVs, I am also considering the Volti audio Lucera…anyone that has heard the Tannoy and any other suggestions which will be better would be appreciated….I have a few first watt amps and several tube amps…plus Jeff Rowland and Pass Labs amps..
