Review: B & K Components ST-202 Amplifier


Category: Amplifiers

I mostly listen to rock and jazz,with the emphasis on
rock.I love the detail's from low to high.And this amp
delivers the goods.It is not too bright sounding,very
neutral highs and mids,and the bass is outstanding.It
has a much better bottom end than the adcom 545.And
it sounds much better than my B&K ST 2140 which I bought
new.It has a very smooth relaxed sound,very much like
the Linn LK100.It does the music justice for the most part.
It made my klipsch KG 2's sound a ton better.They are
very finiky speakers,but the ST 202 brings out the best
in them.And with my Altec's the sound is amazing.Really
too powerful for that type of speaker.
The build quality is excellant,premium parts are used
inside and out.And it operates flawlessly.
My only complaint would be the placement of the speaker
posts.The posts are right under a fuse and it is very
hard to get a thick speaker wire into the hole in the
screw plug.But that's about it.I would seriously consider
buying this amp over a new Adcom or B&K,it sounds much
better.And with 150 wpc it can drive just about any speaker.
I would give this amp a 8 out of 10 any day!
