...Considering the alleged incompatibly
issue of the M8 500s power amplifier with my MartinLogan Scenario
electrostatic speakers, I have to consider the fact the M8s 700m
monobloc power amplifier is a similar ‘bridged design’
but with higher specification (and dual) power supplies. I will
be keeping a very close ear to my speakers to ensure I do not
hear any form of degradation in sound quality...
During the first week of October 2020, much of
the UK (like most of the world) was (and still is) learning how
to decipher changing government rules and guidance regarding ‘the
virus’. Schools were reopening, the rule of six was introduced
with businesses all doing their very best to adapt. The UK weather
also took a turn for the worst with a noticeable drop in temperature
with significant rainfall normally reserved for the Guinea, Solomon
Now, I can cope with the above, BUT I am finding
it difficult to cope with what happened next…
“… this is not about hi-fi, this
more about a musical experience. The band is right here in front
of me!” A quote from a passionate music lover as he
sat in my listening chair Saturday 3 October as I showcased my
new M8s 700m monoblocs.
And then the music died! Well not exactly.
As we explored various albums, reveling in specific
passages, drum patterns and vocals, we began to experience the
now classic Musical Fidelity M8 (anti-ESL) trademark. Slow loss
of dynamics and overall musical magic. The music just seemed to
have gone south for the winter.
Again, to insure my MartinLogan Scenario ESL
panels were still on song, I employed the assistance of a
pair of Trigon Monolog power amplifiers (provided by Audio
Emotion HIFI dealership). As expected, musical dynamics returned
as soon as these power amplifiers were deployed. I advised
Musical Fidelity and Henley Audio of my findings and hopefully
the communication drawbridge has not been lifted!
After various email exchanges and brief verbal
discussions with a few learned hi-fi enthusiasts, it is of
strong belief the power supply/s are the issue (or at least
part of the issue).The Trigon Monolog power amplifier design
pays specific attention to the internal power supply, therefore
providing a stable and reliable feed. Users have confirmed
they have no issues driving MartinLogan ESL’s.
This is obviously unbelievably
frustrating! When on song, the M8s 700m monoblocs have tough
‘musical boots’ to fill and I adored my short
time with them, BUT I now have to confirm the M8 range of
amplifiers (M8s 500s & M8s 700m monobloc) are not compatible
with MartinLogan ESL’s in their current form in my opinion.
I have begged Musical Fidelity
to investigate the above. I have even suggested funding some
type of revision to the M8s 700m monobloc design ‘power
supply/s or otherwise’.(As long as I do not have sell
my house or any body parts)!
The M8s 700m
monoblocs were returned to their substantial cardboard boxes.
I waited in hope for a response from Musical Fidelity (of
any type) but unfortunately this did not happen.
The Trigon Monolog power
amplifiers were returned to Audio Emotion within two weeks.
It was reassuring to hear the consistency in musical delivery
these sturdily built amplifiers offered to my MartinLogan
Scenario ESL’s, but I was not hearing the openness and
full tonal spectrum I knew my Scenarios could deliver. To
get the absolute best from the Trigon Monolog’s it was
clear they needed to be partnered with the Trigon Dialog Reference
Preamplifier. Unfortunately the Trigon Dialog Reference Preamplifier
was not available and there was no eta as to when it would
be, so I was forced to move on.
Onwards and upwards…
