When coupled to the right speaker these amps produce magic with the natural fidelity that SOTA single ended equipment is known for. The 2-Stage, direct-coupled, Class-A circuit design is engineered for long vacuum tube life as well as optimal sound qualities. No capacitors or interstage transformers are used in the signal path.
Chassis, transformer End Bells, and other metal parts are powder-coated for fine finish, durability and anti-resonant qualities.
The amplifiers are hand-wired 3-dimensionally using the finest silver conductors in all areas.
Even the fasteners are chosen for sound quality and long-term durability.
To sum up, we feel that the Serious Stereo amplifiers are among the finest available. It is all 100% hand-wired in 3 dimensional space, hand-secured and lab-tested.
Beauty and reliability to last through the years: Each Serious Stereo amplifier is designed and built to last for decades without repair and still look and perform "like new". Fit & finish are also up to the challenge. We use High-Gloss super-tough powder coatings for all surfaces where it is possible, both inside and outside. The Serious Stereo nameplate is a sculptured brass plate. Carry-handles are forged chromium steel with grade-8 retainers held in place by locking washers and Loctite(R) bonding agents. Strong & well finished.
The best wire: 12ga. Multi-strand silver, some solid silver, all signal-handling wire is by Siltech(R)... only the best will do for your amplifier! Nothing is overlooked in our quest for the music to sound real-- lifelike.
The best signal path: To get down to the best possible signal path, we have really gotten Serious! We have only 2 stages of amplification-- each is a symmetrically-built, "perfect" triode, operated in Triode, Class-A mode. We feel that additional stages lose too much musical expression and dynamics. No coupling devices, such as interstage transformers, or capacitors are used as we feel that these items cause large signal-integrity problems and account for homogenizing, delays, and losses of musical information. Therefore, no coupling devices of any kind are used in Serious Stereo amplifiers. You are listening through silver wire, 2 symmetrical vacuum tubes, and one output transformer. CARDAS silver speaker posts route the signal to your speaker cables. This attention to detail makes all the difference. You get maximum fidelity and dynamics. Music sounds very lifelike, present and real.
