The Solitaire is a straight 150WRMS Stereo Power Amplifi er or can be o ered like the IKARUS as a higher powered [150WRMS] Stereo Integrated Amplifi er. It best embodies the sculptural design and “lack-of-sound” philosophy of Metaxas & Sins. - Page 6 Then, it true “Bugatti fashion”, each and every amplifi er is assembled by the master or his sins — either Andreas or Alessandros Metaxas. The individually 5-axis CNC’d “sculptural” enclosure presents a very heavy, solid, inert, non-resonant structure to RFI shield and ultimately protect the delicate electronic signals, driving the noise fl...

Page 12: Unpacking And Connecting
UNPACKING Carefully remove the SOLITAIRE from it’s FOAM PACKING taking note of how it’s inserted [in case you wish to reuse the Flight Case for future transport]. Using the Alun-key set, you can remove the top amplifi er module cover and bottom plate to ensure that the 2 amplifi... - Page 13 After unpacking, don’t forget to remove the “white foam” which holds the modules in place - top and bottom panels.

Metaxas products belong tothis rare category of electronics which achieve the essential and vital qualities of agood Hi Fi system which drive you to irresistibly listen and enjoy records one after the other”.

- Page 19 However I come to peace with myself by the sound of the IKARUS. The Australian neither over-searches for superfi ne details, nor omits any information. The IKARUS plainly serves the music. Searching carefully for its characteristic features, one what the notices that it produces an exceptionally broad soundstage in the listening room.”...

- Page 27 master tape concert recordings If your concert recording equipment is “exceptional”, you are at least 90% towards creating a great recording - it is then really up to the musicians. It’s actually the same with Hi-End Audio. An exceptional system somehow actually makes MORE recordings sound interesting and involving.
- Page 28 Tuning or Voicing your equipment and making sure it can handle the levels of the music you want to record, is similar to selecting and assembling an Audio “playback” system. My fi rst recording in 1987 with my Stellavox SM8 and a pair of B&K 4133 mics convinced me that it could be the basis of a “reference” recording system with a performance beyond the best existing vinyl playback systems.
- Page 29 I could tell from my fi rst recordings that he had gotten their soundstaging properties right. All that was missing were issues with forming 3D images on that soundstage because of “pro” circuit BMW EDGE Concert Series [sponsored by BMW] practices.

Page 30: Design Philosophy
design philosophy ULTRA-SHORT SIGNAL PATH : NO-WIRE DESIGN A prominent audio designer once described an amplifi er as “A straight piece of wire with gain”. We take this further by featuring the shortest possible signal path in a commercial amplifi er. We minimize wire in any of our signal path and every component is directly soldered to one large printed circuitboard. - Page 32 LOW NOISE, HIGH SPEED VOLTAGE REGULATOR DESIGN. The most signifi cant di erence between VALVE and TRANSISTOR circuits is the amplifi er/power supply interaction. In VALVE amplifi er, the high voltages (from 200-400 Volts DC) result in a 50,000 to 100,000 Ohms value for resistor R. The equivalent transistor amplifi...
- Page 34 If we monitor the V+ point of the transistor circuit using an oscilloscope, we would notice this 0.1 Volts, 1.0 kHz signal. If we were to increase the frequency to 10,000 Hz and up to 1.0 MegaHertz the speed of dynamic behaviour of the power supply becomes critical. Using a normal I.C.
- Page 35 This is the STATIC performance of a voltage regulator which although important, does not a ect the overall sound of the amplifi er as much as the regulator’s DYNAMIC performance which is infl uenced by the speed and ‘open loop gain’ of the regulator.
- Page 36 If we go back to our basic circuit and analysed the performance of an I.C.positive voltage regulator (say a LM78LXX from NATIONAL SEMI- CONDUCTORS)it would have an output impedance at the pin of its output lead of around 0.2 Ohms from DC to 10kHz, and then an increase to 0.4 Ohms at 20kHz, then 4.0 Ohms at 1 MEGAHERTZ which clearly il- lustrates the open loop frequency response has a turnover point around 10 kHz.

maintenance TESTING TOOLS REQUIRED: Dual Channel Oscilloscope Signal Generator 30V x 2 Power Supply Multimeter 1. Flip the amplifi er to reveal the underside and remove the bottom panel [M3 alun bolts]. Remove the VU Module. Rotate the biasing trimpots VR5 & VR5a fully clockwise. - Page 40 6. To test the “capacity multipliers” on the amplifi er modules , measure the voltage across the collector & emitter of Q2,4,16,19] which should drop approximately 2 volts . If a greater value is measured, replace the faulty transistor. 7. Clip a multimeter across any of the 0.5 OHMS output stage emitter resistors and rotate the 18-turn trimpot slowly anti-clockwise until you measure approx.
