sure, we all have our favourite and rightly so. I hold Stephen Howard's opinion in the highest esteem but I also know that his findings were relative to older runs of the SX90R and that they were not across the board (he also found some well applied rims not only faulty ones) Besides, just before of the crisis (which seems to be resolved by the way, I know from a good source that they are now delivering horns to shops as we speak) they introduced the new Toneking which is a Sx90 without the rim on the tonehole.
Frankly, Selmer, Yamaha and Yanagisawa are great horns........but have a weak personality, this is not the case with a Keilwerth or , Rampone & Cazzani or Borgani
