New York studios, the PRS1.5 preamplifier acclaimed
after 30 years of quest for the Grail
Passionate New York based
multi-platinum record producer and sound engineer, owner of a world-class Tom
Hidley designed recording facility, Mic A., in his quest for the most
accurate and natural sounding monitoring, had already replaced the famed
original Swiss made amplifiers with JMF Audio designed mono amplifiers years
Mic A. is one of the few to have
maintained a full analog workflow, using a collection of equipment which
sonic character is sought after by the artists and the record companies to
create the sound texture that suits some types of musics. However in the studio
the engineer cannot adjust, correct or tune what he cannot hear, thus accurate monitoring is key.
Sound engineers work by listening. Mic had always wanted to hear exactly what was on the mix bus of the
large analog recording and mixing console. The integrated control section of the console itself
was not enough precise to him to reveal the precious information. Therefore Mic
decided to get inside the console and place wires on the mix bus to link to
an external and more accurate line stage to feed the power
amplifiers and speakers (monitors).
For this external line-stage, Mic
had tried professional and high-end audiophile units for years. Swiss,
Danish, American... all more reputable and expensive than each other, but
none was 'transparent'.
Moreover, the line-stage had to serve
as a neutral switch between the console and a known source such as a commercial disc
for the engineer to reference his work along the process.
In 2017, Mic approached JMF Audio
of France and placed an order for a PRS1.5 preamplifier, customized to
handle the high magnitude signals of the console. JMF Audio was working on
the revision D for the PRS1.5, which was aimed at making the PRS1.5 the most
natural sounding and pure path source selection and volume control possible.
In JMF Audio studios, the PRS1.5-D, inserted in-line, volume set so that the
output level is the same as the input level, actually was proven equal to a direct link on measurement and
listening! (the said reference direct link being no less than the JMF
Audio CM8-C interconnect, the purest to date!). From this test we have
been able to consider the PRS1.5-D as an audio element of absolute fidelity! **
This was defined as impossible. JMF Audio has made it.

"I received and installed the PRS1.5 [...] I was blown away... The sound
character, tone, detail, musicality, timing was like nothing I ever experienced . It was shocking!"
[...] "It became so involving I just left the CD playing to the end... I was jumping for
joy... You know something is good when you hear so much more information on the CD you never heard
I started to hear detail around the vocal I never experienced in ANY line stage...
I still have to see how the low end resolves on big speakers.
Thank you for YOUR dedication.... I want you to know I really have NO EGO, I just need the best for my soul and clients."
"JMF Audio PRS1.5 is outperforming my previous preamplifier by a large
margin! I cannot believe this."
"Nothing short of amazing!!!!!!!!! The low end is stunning!!! PRS1.5 is kicking
ass... I love it... It's mine for life!!!!!!"
"Listened again this morning to a whole CD with amazement! You created a
monster! I heard so much detail on the disc I never heard before.. and the way I heard it is really impressive. There is no doubt the musical timing, feel and energy using the JMF
Audio PRS1.5 is world class!!!!!
I know this is funny but I used the same 10 CD's I been listening to for 20
years! I know them well... The PRS1.5 preamp is like I just bought them...
I hear things on them I NEVER heard... and placement of instruments....wow is all I can
say!!!!! really... you did it! Congratulations !!!!!!!!! Laurent.......A breakthrough in
sound!! A new world reference!!!!
I will call all my really experienced producer friends one by one to listen. Please inform price for new one and delivery time, since I am sure they will

**This particular test
setup is highly relevant and meaningful. Indeed, it does not only
allow us to consider
the PRS1.5 revision D as an absolute fidelity audio
element, it also validates the JMF Audio technology as a whole : the
approach, the design, the unique
PGP gold printed circuits boards technology, the made to measure components,
the neutrality of the components active or passive through which the signal
flows, the CSV dual mono volume control, the power
supplies technology, the isolation concepts, the mains conditioning
through PC3 cords and the PCD302 filter that power the unit... It
means JMF Audio products' DNA and this leads to absolute fidelity!
"A breakthough in world
class audio...". According to Mic A., multiplatinum record
producer, New York.
