started with the "Hobby" about thirty years ago (with six
years) with a Grundig Solid-State tape recorder which was a
gift from my father at Christmas - time. Since that time I
was always struggled in good sound reproduction. My great
goal to become a "Tone - Engineer" as a profession is
unfortunately not reality. A "normal education" has taken
place instead of that. Today I'm working in a huge Computer
Company which has the three big letters on the Buildings! (
or on the PC's ). BTW, some Friends told me, that it
would be a shame to me, to have no private PC. They're
right, because I've worked with my PC only in the
"Company", but I see that there's a need for having one at
home too (enormous possibilities in the net which are still
increasing and especially a lot of "High - End" infected
people.....) But now back to the
With my first "earned money"
I ordered the kit for creating two Speakers. I was convinced
about the theory, the more systems they consist of, the
better it should sound. ( poor boy.......).
Now it follows a long period
of changing Speakers and cables and Amps. and so
After a while I thought by
myself, that it couldn't make sense to change the
Equipment several times. But indeed, all "normal Speakers"
are sounding different and the Ears are totally complex.
There is a "need" to find the Sound itself, but it seems
that the goal isn't reachable with much money or new
"Brands" You can spend money with no limit to the top and
you've always a "Compromise". At this time i worked in the
Opera House as a Technician and was involved all days in
this huge Opera's behind the stage.
There was so much "Dynamic"
totally there and something which is called "the
untouchable" In Cinema's i often had the similar experience,
but if i start closing my eyes, the Speakers were present
A "Private-Offer" in a Hi
-Fi magazine has changed the situation in
I remember to the text:"
Tube Amps and a pair of Klipsch for sale
This was the beginning of a new
challenge in Hi-Fi for me.
Meanwhile the Klipsch has gone
and there are Fullrange-drivers instead.
But the "Horn - Principles" are
still my Bible.
No other System (in my
opinion) can offer this dramatically huge

My personal taste of music is
75 percent "Classical" and the rest "Hard Rock and Soul
In the classical section my
"Tops" are the Opera's from Puccini and Verdi. ( Turandot
for " tuning" the set....).
The modern Operas from Philip
Glass are also a "must". ( Echnaton,

AA: "Roland, how
would you describe your system's sound?"
RH: "The system is
dramatically "real" in my opinion. I played the classical
Horn in an Orchestra 20 years ago. If i listen to my master
tapes, the illusion is perfect !!
AA: "Do you think there
is room for improvement?"
RH: "Yes", i need
