Hi Wilfredt
When you originally posted I had ordered a Decware Zen Torii MkIII amp and was anticipating using it. I had been using a pair of Bottlehead 300B Paramount monoblocks, wonderfully clear and musical 8.5 wpc. Very good until I wanted a high volume rock concert or Beethoven's Ninth. Very close, but not quite enough. Next I got a Primaluna Prologue 5, 36 wpc, KT88's, no NFB. Plenty of power, very good sound, just not quite as transparent as the 300Bs...
After I read about the Zen Torii I decided that it would be
good to try it out... el34s, 25 wpc, strong transformers, tube rectification and fully choked. It is advertised as
giving the clarity of 300Bs but more power. I have had mine since early June and it is living up to the promise. I put the Tannoy footers on and realized much better detail and clarity as well. The amps mentioned above by others are certainly quite good, but the Zens are about 3 thousand dollars plus shipping. You may read and decide for yourself at www.Decware.com. There is around a 3 month wait while they build yours, and though you secure the order with a credit card you are not billed until it is shipped.
