Mr. C.M. (HQS9001, PRS1.5,
"Saturday I plugged the (PRS1.5) preamp in my Mark Levinson 436. Right from the first notes: clearly
superior to my ML32, better hold low frequencies and more dynamic, unique
JMF Audio mids for musicality, wider and nearer sound stage. In summary:
more music and less hifi. A reference preamp to be associated to all power
amps. Congratulations on this success!" Mr. C.M. soon after
purchased HQS7001 power amplifiers, and later upgraded to HQS9001.
M.I. (HQS7001, PRS1.5, CM4, SR8, PC2), Asia, JBL speakers:
were shocked (when we first listened with the PRS1.5 and CM4B cables). What
I can say is that the sound is very flat over the frequencies and the sound
has become soft. At the same time, it sounds as if it is with very very very
high resolution. Moreover, [...] I am experiencing what you meant by *wider
sound stage, 3D rendering, air* ; which you used to explain the HQS9001
performance at the beginning of the communications with you. [...] My friend
(who owns the) Accuphase C-2810 prefers the PRS1.5 [...]. Thank you for
providing jewelry products."
R.Y. (HQS6002, PRS1.5, SR8, CM4), Singapore, formerly Wavac mono amps and
"I’ve been using a Japanese brand (tube amp) called Wavac and cables were either Argento Audio (Denmark) or Crystal Cable (Netherland). The most notable difference was the liveliness of the music, the soundstage and details. Your amp is also quieter."

J.P. (HPM500, HQS9001, PRS1.5, SR8, CM4, DXC6.10) formerly Lamm preamplifier
admitted that with your DAC [version 1] the sound was excellent without a
preamp." [...] When the PRS1.5 came out: "I have had very
good feedback from my trusted friend. Please reserve one for me." After
reception: "It is true that with the addition of the PRS1.5 and the
DAC running at full resolution, the result is sensibly better on every
aspects. Your next clients will be very surprised."
A.M. (HQS9001, PRS1.5, DXC2.2 MKII, SR8, CM4) formerly Spectral preamplifier
first tried the [JMF Audio] DXC2.2 [version 1] with and without my [former]
preamplifier. I didn't find an improvement with the preamplifier. So I sold
it and I was confident using the JMF Audio DAC directly, given that I have
digital sources only." After demo of the PRS1.5 prototype: "It
is shocking. The sound is greater. I must plan this purchase. Please keep me
posted with the first clients' comments." After delivery: "I
can listen louder, the sound is clearer, wider, more lively; there is so
much more information... Congratulations for having taken up this challenge.
I can believe that the other clients are amazed..." Mr. A.M
later upgraded to DXC2.2 MKII.
"Owner of a high quality Linn system (Komri Aktiv (8 Klimax solo…) linked to a Lenco 75 JTN (I am a vinyl addict), I
had been looking at replacing my Klimax Kontrol preamp for years.
After analyzing the market and a few tests (Audio Research, Mark Levinson…), I was not satisfied about the results,
especially for the price, a friend suggested me JMF Audio that offered to test at home their PSR1.5 model. After one week of direct comparison, I concluded: what a superb transparency! More details.
Simply Music. The three dimensional rendering is gigantic. Loudspeakers and walls just disappeared… It confirmed me
that even if the source quality is very important, the preamp quality shall not be neglected. For myself, I have
found my happiness
[EDIT] the last preamp of my life... My system is now musical… Before acquiring a new high price preamp, I strongly advise to evaluate JMF Audio…"
