Here's my 'review' as posted at www.audiocircle
I'm not really a reviewer but here
An audiophile friend was kind enough to lend me his single ended
pentode 9W integrated amp [a popular one] which I was able to compare head to
head with my AKSA before I apply the Nirvana upgrade to my AKSA 55W.
stock form, the AKSA was on par with the SEP amp. Actually, it could be better
but I had to strain my ears to hear the diff. True to its promise, it doesn't
sound like the typical solid state amp. In the stock form, it already sounded
like a tube amp which sounded 'sweet' - liquid midrange and silky treble which
is not harsh and edgy at all. The bass of the SEP amp was there but is not as
defined as the stock AKSA. Had enough of comparing since most of the time the
sound was really similar so I decided to go on with the Nirvana upgrade.
couple of days passed. AKSA upgraded to Nirvana. Break-in period may or may not
Well, like what everyone was saying, the Nirvana upgrade is 'worth
every penny'! The AKSA55N is now completely a different beast. The first thing I
noticed was how solid and defined the bass has become. I would imagine comparing
the stock against the A55N version and would term the stock bass to be wobbly
and out of control. With A55N, there is speed and slam! The bass sounded deeper,
defined and almost real! Overall, I would sum A55N's sound to be very involving
like a veil was removed and now I can clearly hear the music like it's supposed
to sound. Every sound has its own character and space on the soundstage and they
all sounded so natural and very distinct. I really could tell the diff between a
nylon classical guitar and a steel string acoustic guitar. Sound would come from
outside the left and right speaker boundary which leads to a wider soundstage.
The soundstage has become deeper as well and with more height info.
confirm, I again hooked up the SEP amp and listened to my test tracks.... then
switched back to A55N... darn! I was shaking my head. My impressions was
confirmed. It has become a better amp and everything improved which put a grin
on my silly face. The difference could easily be discerned. Indeed, this is
really a VERY musical amp!!! It has the liquid midrange and silky treble sound
sought from tube amps and the deep solid bass of a high powered solid state amp.
