9.0 More information about your I-30HD integrated amplifier.
This is a Class A push pull integrated amplifier where two vacuum tubes
are used. One tube “pushes’’ current out into the loudspeaker while
the other “pulls” current from when necessary and as a result the signal
pushed into a speaker is therefore amplified.
One benefit of a push-pull design where this leads to higher power out-
put over a Single Ended Tube (triode amplifier). Another is where there
is less current drawn when there is no sound. Both are inherent benefits
of a push pull amplifier. Unlike a SET amplifier, additional circuitry in-
side generates an output of the wanted audio signals and removing un-
wanted ones that add to distortion.
This amplifier may use either 6L6G, 5881, or EL-34 power amp tubes.
It is supplied with “Dared” 6L6G tubes which we feel provide you with
the best, natural sound. Your amplifier has an automatic internal bias
system that adjusts over the life of the tube for best performance. This
feature also allows you to experiment and change out the same model
tube with tubes manufactured by different manufacturers. Many audio-
philes like this where they can fine tune the “sound” or “color” of the
amplifier by changing out tubes to accommodate the types of music
styles listened to. While tubes from varying manufacturers have the
same model number,
Tubes “do have” a “sound”. For those so musi-
cally inclined, gut and metal strings sound different on the violin, and
violinists select strings to define their sound, and likewise guitarists
select their tubes for sound.
Having said this, you will most certainly enjoy more “tube” sonic char-
acteristic from this amplifier than others on the market today. You will
also appreciate this amplifier’s soundstage presence and its dynamics
and high resolution sound with a very low noise level with musical bal-
ance.
Time for you to enjoy your I-30HD!
