Grimmie Posted July 12, 2017 Posted July 12, 2017 I love my CD2, it's been a fantastic player for 9 years but after all this time the little 12v power supply has given up the ghost. I've considered buying their VBS (Virtual Battery Supply) many times in the past but was unsure of the value / improvement to be had and BC gear is pretty exxy. Not a problem any more as they're discontinued but I do need to find a decent replacement for the dead one ASAP. Lots of talk on various sites that switch mode PSU's are nowadays better than linear with their humming trannies and magnetic interference https://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwiAyJzw4IPVAhWCbbwKHVrEDjEQFggkMAA&url=https%3A%2F%2Fbenchmarkmedia.com%2Fblogs%2Fapplication_notes%2F152143111-audio-myth-switching-power-supplies-are-noisy&usg=AFQjCNHuWMfCGglWuk1N3gR_IQwK2UTdqg (how do you abbreviate those links) but I guess they would say that, likewise the linear manufacturers and fanciers. A company called Sbooster make one for 300euros or 368 for the 'ultra' model but they don't look like anything special, that is just another computer PSU, they have rather better spec's though. Altronics do a 12v - 3amp unit that would do the job for $56.00 but that's not going to be real crash hot either. Anyone done the hard yards on this subject and would like to share their experience on PSU's of all types? I don't mind spending that sbooster kind of cash if it's going to be a real improvement on the existing. (Prior to kaput-ness that is)
Gieseler Audio Posted July 12, 2017 Posted July 12, 2017 I have recently added a 12v 3A low noise linear supply to my range which would be ideal for the CD2. It uses a large 6A potted external EI core transformer which is very quiet & definately no magnetic interference as it can be located well away from the PSU itself. All components are high quality (no Chinese stuff) with a total main filter capacity of 20,000 uf. I recently supplied one for use with a nimitra sever with good results. Scroll up a couple of posts to sandrews888 Cost is $350 delivered (Aus wide) - it comes with a full two year parts & Labour warranty Cheers Clay 1
a.dent Posted July 12, 2017 Posted July 12, 2017 @Grimmie I'd go for the Giesler PSU that Clay makes. Great quality and excellent value for money. I bought a Giesler 12V PSU for my Mytek DAC and now it is in use powering a DIY seerver. Works very well. 1

Grimmie Posted July 13, 2017 Author Posted July 13, 2017 Looks like you have a few fans Clay. I'll check the pennies and PM you. I must admit that I had kind of expected a linear versus SMPS type of argument to strike up as I have found quite a few articles on-line stating that modern switch-mode power supplies are actually quieter and cleaner as well as more efficient. Perhaps the limited requirement for them would also limit debate or opinion. After all, if you don't need one, who cares? 1
Gieseler Audio Posted August 14, 2017 Posted August 14, 2017 (edited) Ged I have just had a look at the CD-2 specs & it needs 12v dc with a max of 15 watts. I actually have two PSU's that would suit it. 1. My 9/12/15v which I can pre set to 12v. It will actually supply about1.7A at 12v so 20 watt rating. Cost $325. 2. 12v only 3A unit which has a 36W max rating. Cost $350 They will both do the job ok but the 3A one will run cooler as it will only be running at about half capacity. Your call.

I don't mind spending that sbooster kind of cash if it's going to be a real improvement on the existing. (Prior to kaput-ness that is) Hi again, Ged, I signed up to be an Sbooster dealer a couple of years ago as I wanted to see if: a 12v one would make my new miniDSP 10x10HD sound better (the miniDSP was required to deliver an active XO for my 3-way active Maggies plus allow for the sub/bass panel XO), and a 24v one would improve the sound of my Muse phono stage (currently driven by SLAs). I'm happy to say that both Sboosters improved the sound! So I think they are more than "just another" computer PSU (btw, they are LPSUs - not SMPSUs). So an Sbooster is certainly one option (as is a Gieseler). On 7/13/2017 at 4:25 PM, Grimmie said: Looks like you have a few fans Clay. I'll check the pennies and PM you. I must admit that I had kind of expected a linear versus SMPS type of argument to strike up as I have found quite a few articles on-line stating that modern switch-mode power supplies are actually quieter and cleaner as well as more efficient. Perhaps the limited requirement for them would also limit debate or opinion. After all, if you don't need one, who cares? I did some experiments with different PSUs for my 'Number9' TT motor speed controller. This is normally driven by a 48v Meanwell SMPS - so, at that voltage, an Sbooster is not an option. 5 PS arrangements were compared. In order of increasing SQ, it went: Meanwell. 48v LPS (designed by Hugh "Mr AKSA" Dean). 48v SLA supply - 8x 12v SLAs ... arranged in 2 pairs of 4 stacked SLAs. (2 parallel pairs to halve the Zout of the batteries.) 48v LPS with a hash filter between it and the wall. Meanwell with a hash filter between it and the wall. Digital systems (like your CDP and my speed controller) often like a fast PS - which is what a SMPS is. The problem with the SMPSes is mainly the crap they inject back into the mains - which buggers up other components. So if you can stop this crap with a hash filter ... you can take advantage of the high speed of a SMPSU. So a hash filter plus a standard 12v wall-wart may deliver better sound than an Sbooster - or a Gieseler - for your CDP. Andy Edited August 15, 2017 by andyr 1
