Jim....here's the issue.  You probably already know this.    The fans inside the old PS3 blow air OUT.  So people who put external fans to try to cool the units made the internal fan work even harder and created more, not less heat.  I agree we need to come up with some sort of internal solution to cool this thing, but i haven't figured out what yet.  The guy I bought from is a PS3 expert and he's still struggling with solder melts all the time.

I thought there were fans available that would specifically connect to the PS3? Meaning (I'm assuming) it would also suck air out of the machine....

Take a page from the Cray-2: dunk the whole thing into non-conductive artificial blood plasma.  A cheap alternative is to use cooking oil instead, but it is rather messy...

I think most after market fans for the PS3 now are designed to "suck."

Yes, i'm sure there is a solution.  I'm already in for about $400 to rip a relatively small SACD collection.  biggrin.gif

How small is relatively? :P. It could grow to a large collection once you hear how good SACD is. tongue_smile.gif

Somewhere in the 30-50 range currently including complete works of Dylan, lots of classical and jazz.  Already have a taste of how good SACD is from downloading DSD.  You started all of this with Hotel California!!!!!

LOL I remembered that.  HDtracks has it in 24/192, so how does it compare?

[OT] but HarryB, do a quick google on PS3 reflowing (temp) & PS3 reballing (a little bit more permanent). I've done reflowing myself. It's basically the heat of the GPU is so hot it unsolders itself. Feel free to PM me for more info but I think google will provide sufficient info.[/OT]

Frankly, I'm not hearing a ton of difference between 24/96, 24/192, DVD-a, and DSD files.  Often, I "think" DSD sounds better until I do truly blind A-B testing.   We may begin to see more differences with native DSD processing.   Needless to say, I can hear a ton of difference between any of the above formats and 16/44.1 both through my home system and through the RWAK120-S.   I would challenge anyone who is hearing a great difference in DSD to PCM, and other hi-res formats to a blind test.

Listening to Lara StJohns Bach album at the moment (wav ripped from CD using XLD) with my heaven S's right out of the 120. The heavens can be a tiny bit hot on the treble but matched to the 120 the violin is sweet and full of texture and tone, a very un digital performance I feel. No glassy presentation, just sweet and textural, lovely.. Oh the the flat brown cable of the Heavens is a perfect match for the leather case biggrin.gif

Cheers

Looks like a perfect match (both physically and sound-wise)!   And I want one as well, just gotta find someone that sells a Mint condition one ;-)

Definitely a +1 :-)

I would take it even further. Download a good audio converter and transcode one of your favorite 24 bit files to 320kbps MP3 (LAME). I A/B'ed entire albums for hours and could not find a difference.

 

The benefit often comes from the fact that some producers take more time to master their "high-res" files. Convert the better mastered file to MP3, and see if you can hear the difference between it and FLAC/DSD/etc

I agree, am not hearing a lot of difference between certain hi res and DSD, I think I will focus more on 24/176/192 for my high res needs. DSD also drains the battery super fast!

And to repeat my earlier comment for me it is more how the album was engineered and mastered originally that I find makes the biggest difference. I wouldnot recommend the Van Morrison Astral weeks album in high res, it's just not really any better than the old CD I have.
