To achieve the best sound quality from Ypsilon Electronics, we select only the highest quality tubes, test and match them in the exact component they are to be used in. This will guarantee the ultimate performance level.
Ypsilon amplifiers employ the finest tube rectification, and we offer the Mullard EZ81 as an excellent upgrade over the stock tube. Each component uses a single EZ81 tube, excluding the PHAETHON integrated amplifier.
