For our Cessaro Air two we decided to use a single-ended tube amplifier with only two amplifier stages and two output tubes in parallel circuitry. The extreme labourious winding method of the output transformer creates a perfect behaviour even with parallel operating output tubes. Due to the usage of very few parts and directly coupled with only one „plate choke“ between the first and the second amplifier stage, there are no interstage transformers or capacitors in the signal path. This concept results in a super-fast reaction of the pulse processing, combined with a natural sound pattern of highest resolution and emotionality.
The Cessaro Air two uses a simple circuitry, a huge dimensioned output-transformer (custom made core size) specially made of finest core material with silver winding on primary and secondary side, a very low output-impedance, an extreme expensive power supply for the high voltage range and the filament voltage with separate power supplies for each tube section combined with the finest NOS-Tubes. The audiophile listener will experience something special in sound – guaranteed. The perfect match for any real horn system. Audio tube-amp manufacturer all around the world know very well, that it is a challenge to get a tube amp dead quiet (hum- and hiss-free) without using a volume pot in the signal path combined with a very high efficient Horn-Loudspeaker system (CESSARO Beta 105dB 1W / 1m - CESSARO Omega 112dB 1W / 1m).
Please note the AIR two is only available as a limited edition.
