Museatex Meitner PA6i & MTR-101 Monoblock Amplifier System


Besides their diminutive size and great build quality, the first thing that stands out is the uniqueness in design.

The preamp features the optional wireless remote control.

The cabinets are finished in gloss wood and have faceplates with no buttons on them! Back in the 1980's and 90's that was super unusual.

The preamp features very high quality RCA jacks and and an outboard power supply.

The amps can provide up tp 100W each and use conventional banana jacks for outputs. 

All three units go super well together so we've decided to keep them paired up.

They were tested in our lab and are performing properly and reliably.

The PA6i may seem to be simply a preamplifier. It is not. It is the descendant of generations of PA6 preamplifiers. Each one a definitive step forward in the quest for excellence in musical reproduction.The original PA6 pioneered state-of-the-art solid state control for volume, balance and switching of input sources while most designers were still learning mechanical controls. User changeable phono modules. Full remote control. Absolute phase inversion on the remote. Floating Charge Power Supply. Elegance of appearance.

These are hallmarks of the PA6 lineage. The PA6i of today achieves a level of listening experience that we would not have thought possible back then.
The PA6i is more than a preamplifier. It is the cornerstone of a comprehensive Meitner system. Individual components that may be matched with those of other manufacturers for superb results, but which together comprise a perfectionist system of unsurpassed sonic merit.

Frequently, amplifiers that receive the highest ratings for superlative listening enjoyment and their ability to drive demanding speakers are large and ungainly. Consequently they cannot easily be integrated into your living environment. Alternatively, there is a tendency for attractively styled components to prove inadequate when called upon to drive some of the world's best speakers. The discriminating music lover has often been faced with a difficult choice - performance or style; excellence or convenience.

It is our conviction that an amplifier is distinguished by what it does. The task it accomplishes. The throaty tone of an altosaxophone. The attack of stick on snare. The majesty of full symphony in a superb hall. The delicacy of flute. The satisfaction of hearing your preferred music, in the comfort of your home, reproduced as you have never experienced it before.

Passion for the highest standard of musical reproduction shouldn't mean giving up valued convenience, nor compromising the attractiveness of your surrounding. You should be free to choose your speaker without concern for limitations imposed by the amplifier and without having to hide the equipment in a closet.

From these needs the STR-55 and MTR-101 were created, not from conventional design theory, historically unsuccessful in down-scaling thoroughbred amplifiers. The breakthrough, authored by Chief Designer Ed Meitner, was an evolutionary power supply that prevents the contamination of fragile music signals by the power supply. Contamination found in most audio components. The **Floating Charge Power Supply** clearly demonstrates that much of the quality of venerable vacuum tube systems, traditionally well regarded among some critics, relates directly to good power supply design.

A second principal benefit of the Floating Charge Power Supply is to enable these amplifiers to store large amounts of power in reserve for moments of heavy demand by the speaker. Using conventional technology, the same capability would require a chassis of nearly five time the size.

The substantial output capability of the Meitner amplifiers belies their moderate size. Its disarming dynamic performance partnered with microscope-fine resolution of musical details and photograph-like dimensionality of sound-stage recommend the STR-55 and MTR-101 to the most ambitious examples of the speaker art.

Reliability Updates
- The power switch, which was previously a triac in the primary side of the power transformer, has been replaced by a Scritch. The Scritch, an SCR - based circuit, is positioned in the power supply after the diode bridge. This provides for soft turn on and better long-term reliability.
- There are some small, but significant changes to the compensation and servo circuitry, making the amp completely immune to load variations.
- The pre-drive transistors have been upgraded to a new Motorola device. This part is faster and shows less variation from the manufacturer.
