Getting Better Sound Quality Out Of Your Home Theatre System - moving to better stereo performance
Once we have
achieved a certain nadir with our HT system, and begin the process of enjoying
our sound system, we then move to a state of enjoyment, which can last for
years, or unfortunately, for those with a bit of pruritis ani (aka itchy
backside), this state of contentment could last merely months or weeks.
The HT system
could still sound fabulous, but we then start to consider the stereo
performance and ponder if we can do better.
There are
many solutions to this.
Firstly, we
could begin building a dedicated stereo system from scratch. Separate speakers,
amps, sources and the whole shebang. This approach requires deep pockets and
more importantly space, which could be a premium in a small apartment.
Secondly,
we could integrate things into our surround setup. This can be done in a few
ways. Sharing the same front speakers is one way, which minimizes costs, and
space utilization, and but the speaker placement for HT versus stereo can vary
and those pieces of acoustic treatment can also alter the sound negatively.
Usually in stereo, one has the option of switching off the auto-Eq or go to
“Pure Direct” or similar modes on the AV amp.
For
a step up, one can swop out the current AV amp for a more musically inclined
one, but this option can be the most expensive way to do this, as the cost of
the better processor with better music capabilities can be significantly more.
You may also have to factor in the cost of better power amps in order to take
advantage of the better processor. In addition don’t forget cable costs, as one
will need interconnects between the processor and power amp.
You
can save some money by only upgrading the processor and the amps that power the
front two or three channels, as these are the main stars in music performance.
The
third option is to use a stereo setup in between the HT processor and the front
pair of speakers. You save on the speakers, and only upgrade the front
channels.
One
can either get a stereo pre-amp with HT BYPASS and then hook up a suitably
music power amp which then powers the front channels, or buy an integrated
amplifier with the same HT BYPASS function.
So
the magical feature to look for will be this HT BYPASS. What is it?
Well
normally inputs on an amp are variable in nature, which means the volume on
these inputs are controlled by the volume control of the amp. The sound that
comes out can be too soft or too loud causing distortion and even destroy the
speakers.
A
HT BYPASS input on the other hand, has a fixed level input, and the volume
control on the amp is disabled. How loud the speaker is driven will be
controlled by the AV processor.
This
also means that after you swop in the new amp, you will need to re-do the
auto-EQ for the best level matching.
Just
ten years ago, finding an amp with this HT BYPASS would have been harder than
looking for hen’s teeth. But now, even mid-priced integrated stereo amp will
have this function. It goes by a variety of names, some use a switch for a
regular analogue input, others have dedicated “Power Amp” inputs, but the
function remains the same.
Do
remember that for certain models, the amp can go very loud if the source is
still playing when you switch in or out of the HT BYPASS mode, and this can be
damaging for the speakers so do beware.
Some
stereo amp even allow for more than one speaker to be hooked up and you can
then use another pair of speakers for stereo performance, allowing you to keep
one setup for HT and another to be powered by the same amp for music. These
amps usually have options for “speaker A” and “speaker B”.
You
can then hook up a music stereo source such as a dedicated CD player instead of
using that Blu Ray player for music, or a DAC to improve the sound.

The challenge with the stereo amp is hooking up your existing sub, as most subs only have a single low level connection. So, advice is if you want to go down this road is to consider a sub that can allow high level connections together with low level connections from the beginning to retain this flexibility!
