Rens Heijnis custom-built audio equipment

They have a beautiful, neutral, natural sound that we want to listen to forever.
Active powered microphones (+60v)
Below you can read the opinion on active powered microphones of some recording engineers:
TLM49, David Spearritt
The modification that Rens has implemented has improved the TLM49 significantly.
The upper midrange brashness or exaggeration is gone, the
top is sweeter, and the bass appears
to have a slightly greater output and more balanced with the rest of the spectrum. Very impressed.
1) I was never really satisfied with how they sounded but after the retrofit:
They captured the group very well and the sound is excellent. They are less strident now.
The piercing treble sound is gone---much smoother.
2) A smooth clarity and openness that was not present before with these mics
was immediately evident.
I am very pleased so far!
The conductor here is very happy with the 4041 sound - and me too. Huge difference.
I have even pointed them down, towards the strings which was a crime before your modification.
I am very enthusiastically about the Schoeps after the 60V retrofit.
Battery powered pre-amplifiers
Below you can read the opinion on the battery powered pre-amplifiers of some recording engineers:
I like the sound. It is very pure and lovely to listen to. Your preamplifier is making a really nice
difference here, It sounds fantastic.
It has got the superb sound that made me impressed.
I am very impressed by your system. The words that come in my mind:
Very natural, quiet, round, more body, warm, intimate, you are directly involved.
It sounds a lot less electronic.
Headphone amplifier, Gonzalo Noqué
I´ve finally spent some time with the headphone amplifier, it is amazing!
I´m amazed by the level of detail it brings, and specially regarding the "spatial" feeling.
Before modification of Flea microphones: I like the body and the depth of their sound
but they are definitely too harsh and acid...
After modification: they are softer, less harsh and give me a lot of satisfaction on the orchestra.
