Well I know which way I'm inclined to jump with my next purchase, especially
given my near non-existent budget - because ...

I got the surprise of my musical life last week! And I've been a musician for
35 yrs, owning what stereo gear I could afford, and also trained (but didn't
finish the training, due to serious health issues) as a radio/TV Tech a few
decades ago.

After having $1,200 of Harman Kardon integrated amp die on me after about ten
years (unrepairable, according to the shop; specialised parts no longer
unavailable), then a fortnight ago having a $3,000 British Made Creek Audio
integrated amp (the only integrated amp to rate with the separates by US
Audiophile) die after only four years (still in shop, waiting on verdict), in
a fit of musical deprivation I dragged my husband's scorned old receiver out
of the garage (after nearly dropping it due to the substantial and unexpected
weight) where it had spent the thirteen years of our marriage, unable (so I
thought) to be in the same room as my $12,000 setup. I connected up the Tannoy
Little Reds and my Nak, hit 'play' on the Nak - and got the shock of my life.

The HK in particular had been advertised as being able to produce exceptional
dynamic range due to having an extra powerful power supply. The Creek was
supposed to be even better. They were rated at 75WPC and 85WPC respectively,
but the old, late-seventies, middle of the range 35WPC Kenwood KR-4010 blew
them off-stage. Not only was it considerably louder despite its low rating,
but its much greater dynamic range told me exactly why it had weighed so much;
bloody great power transformer and a pair of big electrolytics to help out.
Some punchy amp for such low wattage. Nice tight clean bass; punchier, tighter
and cleaner than the Creek's. It had those 12" drivers thoroughly under
control.

The midrange and high end lacked the airiness and clarity of the Creek, but
I'm only just started on this new toy. Deoxit sorted the scratchy pots. When
the service manual arrives I'll be testing for DC offset at the outputs and
that should clean up the slight mid / high range distortion. I'll replace the
differential pairs if necessary. Then I'll spend a wee bit of time and money
replacing the electrolytics (why such a fuss is being made about such a simple
procedure is beyond me; you can't miss them on the board and they're not heat
sensitive enough to be a problem for inexpert solderers). Then if I get
power-hungry, or want a cleaner high end and don't yet have it, I'll go for
one of the seventies flagship models off eBay and do the same.

Of course, 35W x 2 still needs to be turned up quite a bit to match my 30W x 1
Fender valve guitar amp, but ... RMS - who needs it (apparently)? I've given
up believing in the power output on spec sheets, personally.

I need to feel my music as well as hear it; maybe it's a musician's thing ...
If I had thousands to spend, maybe I could buy a new amp with the punch which
was taken for granted in the seventies, and which would need to be couriered
to me: but I haven't ... so next stop; high end 70's
Sansui/McIntosh/Kenwood/Pioneer/Marantz/wotever.

Wish me luck, Major Jocelyn ;-)
