I love it!  Know any other good ones like this?

A cheapo $600 DAT deck outperforming $2000 analogue decks?  har har har!
Leave those scopes alone and listen to the damn thing!  The *APPALLING* ADC
set ups in consumer DAT decks with their magnificent pre-sampling filters
are just a joy to behold.  Har har har!!!!  Not to mention the things being
full to the brim with poxy op-amps giving cheaps**t Japanese sound.

Sheesh, do you people only listen to bass?  Are your ears so damaged by
years of excessive volume listening that you cannot hear the detail you are
missing?  The life?

Besides which, $2000+ is rather thrifty don't you think?  Not really the
sort of cheap tat that a recording studio would mess around with.

I paid about 850 for mine a 1010. Before making the descision on that amp 
I got to try several pieces for a week at a time. I tried the 610 and I
tried a 
few of the Sony AVR's. In my opinion the 1010 was the only one that
functioned
acceptable as a music amp as well as a video surround processer.

A friend of mine recently brought me a bose speaker which had been

it be cost effective to have it repaired, assuming that's even possible?
 Maybe I could just sell the case.  It's that one that comes in the
plastic case and has two triangular ports for bass.  No; I have no idea
what model number it is.

Any help greatly appreciated...

A store (real store with service dept and salesmen, not mail order place)
in Santa Fe had the 545II for $450 and the 555II for $700, which were "sale"

I can think of three things:

1)  Stereo Review made a mistake in their listing.  (I double checked
    it.  It does say 100 x 2 into 8 and 250 x 2 into 4).

2)  Spectral made a mistake when they made their claim.  Perhaps
    they meant to say "dynamic power" for the 4 ohm rating, or
    they are simply being very conservative with their 8 ohm rating.

3)  This particular amp may have been designed to be used with very
    low impedance loads, and although capable of delivering plenty
    of current, it has a voltage limit which prevents it from
    delivering full power into "high" impedance loads.  That would 
    imply that it would not be a constant voltage device between
    8 and 4 ohm variations. It does have an unusually high slew
    rate, and although that doesn't mean anything in itself, it
    does seem to imply that this is a rather unusual piece of
    hardware.   

In any event, it doesn't really matter, since I goofed.  The amp
which was originally mentioned was the DMA-180.  I listed the
specs for the DMA-80.  My fault.  :-)

Your amp will NOT be expected to work any harder than it already is.
The amp is already putting out power in the frequencies in the sub
band. 

The DAK has an internal high pass 12dB per oct crossover.  This
crossover will channel anything above 120 Hz to your infinity's and
the rest to the sub.  The sub side if the speaker is "acoustically"
crossed over,  the foam material and the way the speaker is loaded to
the rooms air mass is supposed to reduce it's HF output. 

I have found that it doesn't work as advertised and I have used fiberglass
insulation to absorb the mids coming off the speaker (I haven't
electronically crossed over that system yet).

Adding a passive sub to your system should enforce the reproduced
sound at the sub's frequencies.  The total effectivness will depend on
the sound level match between this sub and your main speakers.  If
your main speakers are really efficent then the sound  won't be that
good.  If your main speakers equal or are less efficent than the sub
you will be inpressed.

I have used a DAK sub in the living room, with the internal
20 watt per channel amps in the T.V. and had a wonderfull time!
T2 has some wonderfull bottom end,  so does Robin Hood:Prince of
Thieves.

The best effect will be had with active electronic crossover between
the subs and the main speakers.  It will also let you use an equalizer
on the sub only to flatten out it's response.

If it is not a problem due to bias adjustment then it is most likely a problem
of recording calibration. When using dolby it is necessary to 'tune' the tape
deck for the tape sensitivity (in most decks called REC-Calibration). If not
so then, when decoding the recording, Dolby (type C more than Type B, due to
the higher compression ratio), will be unable to work linearly producing
unwanted alteration (+/-) of the frequency response.

I've got a modest stereo set up in a basement rec room, 7 1/2 ' H

out to the corners to max the stereo effect but that seems to be
a mistake.  Seems like the low end balance has gone off, presumably
being boosted in some narrow range or perhaps select frequency(ies).
By the way my music is strictly acoustic (Irish; some classical) so
accuracy rather than "effect" is what's most important here.

It's my impression bookshelf speakers should be positioned along
a flat wall.  Any comments or generalizations about locating such
beasts would be appreciated.

No, I don't think so.  The dither is only intended to turn what would

signal into the ADC (The 20-16 bit resampling is, in effect the same
as an ADC) you will get the same DC voltage out of the DAC plus noise
at the noise floor of your converter.  You can't _possibly_ do any
better than that.  In theory, every ADC should add this dither before
sampling, but in practice there's plenty of noise there anyway.

i am about to move from the west coast to the east;
movers come to pick up my stuff next week.  i've got
to decide whether to trust my 500 LPs and 500 cassettes
to the movers or consider some other alternative.

my main concern is the records warping and/or the 
cassettes losing some of their high frequencies.

if they go with the movers, they'll sit in a truck
for 3 - 4 weeks.  the truck is supposedly painted white
to reflect heat.  the guy at the moving company assures
me there's no problem--that LPs and cassettes are (or
in the case of LPs, *were*, i suppose) shipped by truck
routinely from manufacturer to distributor and then to
retail stores.  

they only alternatives i can think of are either the
ordinary UPS service (about 10 days), the UPS
"2nd day air" service, which i think is considerably
more expensive, or the u.s. post office--i think LPs
go for book rate.

the LPs are terribly heavy.  i suspect they'd cost a
bundle to ship UPS.  also, i think whatever i ship
through the post office might get handled more roughly
than stuff i send with the movers.  not sure about UPS.

does anyone have any advice or experience with shipping
LPs and records in midsummer?

if possible, please e-mail me directly.  i'm frantically
trying to tie up a number of loose ends before leaving
