Serenada Mk.ll

Our Serenada is a pre-amplifier with 6 inputs. Two are combined with outputs and make it possible to use with a separate switch Tape to Tape function. One switched input selects the integrated phono- stage. Two outputs are available. One standard and one with a -10 dB attenuation for connecting other components such as a separate headphone amplifier. In the Mk.II version an XLR balanced output is serial standard. All control functions of Serenada operate through microprocessor controlled gas contact relays with gold plated contacts. This results no loss of musical details at this important point. The Serenada uses a finely matched ALPS potentiometer with a channel balance of less than 0.3 dB. The use of 1% metal film resistors together with the finest polypropylene capacitors with a minimal 1% tolerance in the phono- stage are standard for Lua's Serenada. The Seranada, now in the revised Mk.II version, has a remarkable history, dating back to the introduction more than five years ago. Notwith-standing its affordable price, the Serenada represents a genuine entry into High End vacuum tube electronics. The integrated phono preamplifier is built to the same demanding standards as the main Serenada amplifier. Considered by many critics to be the finest, most tonally neutral phono section currently available, its design goal was to precisely track the prescribed
RIAA equalization curves with absolute accuracy.
The Serenada reaches this goal with ≤ 0.2 dB. Its supremely quiet high
gain circuitry has been designed to deliver extra-ordinary performance
for the broadest possible range of moving coil and moving magnetic cartridges. The Serenada SEL version represents a big step ahead,
now using double layer polypropylene capacitors, selected together
with a tolerance of less ≤ 0.5 % as coupling capacitors. The finest custom manufactured and selected Lua tubes provide the Mk.II version with its characteristic sonic quality. Through meticulous engineering,
careful specification of only finest available component parts and a painstaking attention to construction quality, we have created what we feel is a preamplifier system withoutrival in its price class.
