Hmmm,

 

is it wishful thinking or could it be true:

 

- not everyone has Pokey stereo, many Atarians still have mono Pokey (PDM)

- not everyone has Covox, many Atarians still have only Pokey in mono or stereo (PDM and PDS)

- but: if someone has Covox, he for sure has stereo available (COS)

 

Which means COV (Covox mono) does not make much sense for me, except maybe that it is 44khz instead of just 22khz...

the quality isnt that great @22khz stereo, too much noise

For PDMs I find the best thing to do, whether you have mono or stereo, is to have powered speakers as a bare minumum. Those cheapish PC desktop speakers are fine, so long as they are powered and you can crank up the volume. Normal TV or monitor speakers aren't ideal at all IMHO.

 

I play my Stereo PDM conversions off my Side3's PDM player on a Stereo A8 with powered desktop speakers and for those conversions that have been done well, (eg so you don't get too much distortion), it sounds pretty good.

1) Stereo A8 with powered desktop speakers alongside the tv:

(power on/off, volume, loudness)

 

 

2) to the right side is even more power - my Hifi stereo system:

(often connected with the A8's stereo output)

 

 

top to bottom:

2x JVC Tapedeck

lots of Mini-Discs

1x CD-player

1x Mini-Disc recorder

1x CD-recorder

1x Receiver

(and 4 large three-way speakers)

Okay,

 

tf_hh removed the Lotharek stereo-enhancement and built-in his own stereo-enhancement in my Atari - and now it sounds as good as the other stereo A8.

 

(If the Pokey chip would have been bad or defect, then it would still sound bad since the Pokey chip was not replaced, but it does not sound bad, it sounds really good now. So I conclude that it was really the Lotharek stereo-enhancement that was responsible for the bad quality of the sound in that computer.)

 

Guess that Lotharek really made the mistake with his stereo-enhancement that tf_hh mentioned in his posting, but I am happy that all is good now.

OK - I am pretty far into the "way the hell overkill situation".  My two "listening rooms".  Not pictured are my two "spare" Comtech 1610s which will each do a massive 875*2 into 4 ohms (all day every day).  All amp specs are full RMS at sub 0.05 THD and I have certified all of them on my test bench.  I can only test one channel at a time on the Comtech 1610s as running a sine wave into my load block, one channel can pop a 15Amp breaker!  To really crank them, I'd need to re-wire them for 240VAC operation.  Those 2 amps are going to drive my ultimate cabinets, I have the drivers but haven't had time (or space) to build them.  I have 4 18" subs, 8 12" bass/mid drivers, and 8 super tweeters.  Dream setup - I really hope I get to build it soon.

 

None of the amps are new little lightweight BS Class D stuff.  All 19" rack mount pro-gear, 40 to 65 pounds per amp)
Denon AVR-X4700H (used in pre-amp only mode for AV switching & some signal processing)
Behringer DEQ2496 EQ and DSP for the front channels
Behringer DSP8024 EQ and DSP for the rear channels
Crown DC-300A Series II powering the subs (490*2 into custom 2 ohm subs - 12" ported cabinets)
Crown D-75A running bridged mono into center channel speaker
Crown DC-300A Series II powering the subs (300*2 into custom 4 ohm rears - 10" 3-way cabinets)
Crown Com-Tech 800 powering the fronts (490*2 into AAL2230B cabinets - dual 12" 3-way ported cabinets)

 

The quiet listening room - In this room I only ever have one pair of speakers on at a time, and they are not always in this configuration - this is more the testing area for my cabinet rebuild / restoration work.
Yamaha RX-V793 for AV switching and also powering the 2 speakers.  1 is an 8inch 2-way cabinet, one is a rebuilt and customized 12" 4-way ported cabinet
Son of Ampzilla (160*2 into 4 ohms powering rebuilt AAL Studio 400s - dual 10" 3-way sealed cabinets)
SAE Mark 3 (120*2 into 8 ohms powering rebuilt and customized 15" 3-way ported cabinets)
