BIASING CONT.
The output tubes are self biasing and self balancing making reliable performance possible even
with un-matched tubes. You will never have to bias your amp, even after tube changes.
LISTENING
There is no doubt you will find the fidelity of this amplifier superior to almost anything within its
power range, however many people do not experience the full potential of its spell casting
abilities due to weak links in their set-up. Usually speakers and room. Because of the
incredible resolution of this amplifier, you will find it easier to adjust your speakers properly for
best imaging because there is no time smearing, or filtering common in most amps.
Perhaps the amps strongest weapon is the huge soundstage it casts. To hear music get
completely holographic, you need to work on room acoustics and speaker placement. Do not
put your speakers near any walls, especially the front wall. Do not put reflective surfaces (TV
SETS) between your speakers. Pull them out into the room several feet from the front wall and
toe them in to create a triangle with your listening chair.
Take the opportunity to try different speakers whenever possible, you may find that now with a
good amp the differences in speakers will be even more profound. Since you always hear the
weakest link in your system, you will want to pay attention to cables and speaker wires as they
too will make far more difference than you think.
Power conditioners (real ones) are recommended. Clean power is essential. To find out what
clean power sounds like, listen to the amp at 2:00 a.m. when there are no harmful or nasty
harmonics in the power line. Once you have your first out of body experience during a late night
listening session we have a forum on our web site where you can share your experiences with
other Zen Triode owners and get tips on set-ups that really work well.
USING YOUR AMP AS A MONO BLOCK
You can get another amp and bridge them into mono so that you can use one amplifier per
channel for more power. Because the Zen puts out more power into lower impedance loads,
bridging a pair of these amps will net you 6dB additional power before clipping. This is usually a
cost effective alternative to finding more efficient speakers.
