Hi fellow audiophiles, 

Is there any significant difference in sound quality between the 
Rotel RCD965BX and the Meridian 200/203 CD players?  Is it worth
paying $1000 more for the Meridian 200/203?

	Yes, I know. If you think that the amp is bad, you should

	Yes, except those Fisher speakers, as awful as they were,
provided deeper bass at more volume without clipping. They did use
bigger woofers.

	I had thought that the Polks would be easier to drive, but
perhaps they are just a lot more revealing of the amplifier's many
flaws than I had thought. It just seems strange that the amp would
clip on the smaller Polks and not on the big Fishers.

	There is no doubt in my mind that the Fisher is a piece of
excrement and that it needs to be replaced. I was simply curious as
to why the amp was clipping now, and not before.

	Thanks for the reply.

For a detailed discussion of 'digital jitter' as it applies to D/A
playback from CDs see Robert Harley's article on p.114 of STEREOPHILE
for January 1993.  He summarizes papers presented at the Audio Engineering
Society and discusses and instrument Stereophile has used to measure
'digital jitter.'  While it is not the total answer there is some
correlation with subjective sound differences between D/A converters.

You may disagree on scientific grounds but I think this issue has
moved out of the realm of 'bogus techno-hype.'

Sequential Circuits was an American synth manufacturer. They made
several innovative synths such as the Prophet 5 (in its heydey the
Prophet 5 was as popular as the Minimoog before it and the DX7
after it - every pro musican had one), and the Prohphet VS.
Sequential also invented MIDI ( Musical Instrument Digital Interface)
and worked with other manufacturers to have it adopted as a standard.
Sequential's synths were all digital/analog hybrids.

The stmt ``This album was recorded,
mixed, and edited using analogue tape and sequential circuits technology.''
probably meant they were proud of the fact that they used Sequential's
synths for everything (all instruments were synthesized).

You've got 30 watts of power available to the amp - and IF the amp manages
50% efficiency (a maximum) you'll be lucky to get 15 watts output.  I 
think you might want to rethink the power supply.

I have a tape deck in which I have to manually adjust the bias but
since it is  3-head deck, this takes only a few seconds. Besides,
I usually buy blank tape in bulk so once it is set for particular brand,
I don't have to change it for a while. Bias adjustment is only
neccessary when recording, not during playback, so if you buy
a couple of cases of blank tapes at a time, you will still only need to
use BLE once in a while.

	The nice thing about the MD concept is that there is
nothing that fixes the format. Since it is a file-system concept,
it is possible that in the future players will be made that can
read files that are lossy-compressed, lossless-compressed, and
uncompressed. As well, the 44.1KHz/16bit standard is not fixed,
as that kind of stuff can be placed in a file header.

Subject: Any Idea for Improving Damping Factor of ST-70
Organization: The Center for Advanced Computer Studies
Date: Tue, 22 Dec 1992 22:01:32 GMT

Hi DIYers,
  
   A friend of mine owns an early kit model of Dynaco ST-70. I designed
and built a pair of speakers for him (a small 5-1/4 in bass reflexed).
The prototype has been tested by a cheap kit solid-state amplifier and
the bass seemed to be well-controlled (quite tight actually). However,
when we connected the speakers to the ST-70, the bass became extremely
boomy and uncontrolled. I retuned the bass drivers by covering their
backs with cloth, increasing box stuffing, and even putting some foam in
the port, hoping to reduce system Q. The result was satisfying for my
friend (the owner) although I still want it to be a little tighter. So
far I thought I misaligned the box when I designed it.
   One day he bought a used Denon receiver. We connected the speakers
and the bass was so tight that it sounded so thin. I checked the ST-70
and found out that this ST-70 has no optional speaker terminal for
4 and 16 Ohm impedance. The output transformer has only one output tap
for 8 Ohm speakers. However, the speaker I designed is measured to be
quite resistive and rated at around 4 Ohm. The reputation of tube amps  
poorly controlled bass and mismatched impedance make me believe at this
time that they are the cause of boomy bass.
   At this time overall sound is acceptable when we connected the
speakers to the Denon receiver (tight bass is more relaxing than boomy
one..we think). However, the ST-70 produces better treble and midrange
clarity and image. We are trying to find some way to control the speaker
bass when connected to ST-70 without having to replace the transformer.
Any idea?

Firstly, Stereophile is hardly and underground mag.  Snobby?  Well ok,
it might be snobby, but not underground.

Does Sterophile hate Carver?  Who cares if they do or not.

I was not a fan of Carver long before picking up my first copy of
a high end mag.  I used to like Carver until I started to compare
it to other amps in the same price range.  I found so many others
that sounded much better to my ears.  Carver makes a much better
amp than Sony or Pioneer, but not near as good as Hafler or
Parasound (to my ears anyway).

Then you have found the right amp for yourself.

I think a lot of it is that Carver keeps claiming that they
can beat any amp at any price.  They make an Ok amp in their
price range and that's fine.  However, they run around telling
everyone that their $700 amp can beat any $10,000 amp.  That's
an attitude that pisses off peole who know better.

If his <$1000 amp is so good, why does he make a pair of tube
monoblocks for $20,000?

Not only does it piss off a lot of people that he has this
attitude, but that he convinces so many other people of it.
He convinces them so well that they won't even listen to
other amps.  They see him as kind of a con man.

According to Clarinet, Sony is working on a MiniDisc-based system for
computer storage and expects drives to be commercially available in 2 years.
A MiniDisc is simply a direct overwrite, magneto-optical disk that stores
130 MB, and compressed audio is merely one possible application of a MD.
I wonder why MD-based disk drives will take so long.

As an aside, I think _Stereophile_ mentioned that, in addition to read-only
MDs and recordable MDs, it should be possible to have a hybrid MD, in which
part of the disc is recordable, and part of the disc is read-only.

The source (i.e CD's) are 16 bit 44.1 khz sampled). The 1 bit , 18 bit, oversampling and all other tricks  works on that source.
The 18 and 20 bit D/A try to overcome the problem of linearity of the D/A.
The oversampling  is based  on interpolating the 44.1 khz samples trying to 
"emulate" a higher sampling rate by means of (sin x)/x digital filter.
The overrsampling procedure has 2 effects:
1) The  sharpness requirement of the 	analogue lpf  are loosened . A less smooth LPF causes less distortion.
2) The quantisation noise is reduced ,by spreading it over higher bandwidth
