In Reply to: RE: What is a good SACD player now? posted by John PA on November 26, 2014 at 10:25:35
The low dollar solution. Find a Sony NS9000ES. Find someone who still does TV repair or some such. Have them replace the output opamps with sockets. Sony bypassed their caps I believe, so you should be able to have then pull the output bypass caps and replace them with either Mundorf S/G with or without oil, your preference, or with Teflon caps. Get a pair of Brown Dog adapters, single DIP to dual surface mount, as well as some AD825's, you'll need 4, 2 for each channel. Sony runs clean power supplies, so you shouldn't have to worry about that. I think they sell replacement lasers for them on eBay, and if you intend to use it long term, it may be a good idea to get one while they are still out there. You should be able to come in under $800 easy and you'll be pretty close to the best SS SACD player out there. Nearly forgot, have them put in 2 6.8K resistors on each adaptor from Pin 4, to pins 1 amd 7, that will push it pretty much into class A operation. You could go the FET route but I doubt you'd be able to hear the difference.

it was popular a number of years ago. Interesting. The work I can easily do myself. Will look into it.

Can anyone speak about the mods for the player?
I think you'll be pleasently surprised.

Lou-
do you know specifics about the mods for the player?
As in? It's pretty straight forward. I didn't mention the I/V opamp because I know of no best opamp in that position. I also failed to mention basically any cap in the audio path after the I/V opamp should be bypassed with a high quality cap. I used to replace all the electrolytic caps whether bias or in the signal path with Black Gates, but that is no longer an option.

Lou

you don't have any BG's but I have a big load of them, which is nice. I actually like BG's bypassed by BG's.

Cool. I have a few myself, and I used to love to use the little .1uF bipolar to bypass other BG caps. I wonder when the rights to use graphite in the electrolite runs out. I am sure Elna or Nichicon would be happy to make caps that sound as good as Black Gates. I'm half surprised that the Chinese have not done it. They could sell them as NOS. After all any oligarchy with it's salt hoards Black Gates!

Audio Note UK is working on it and should have something near them this summer but they state that the BG is still the best, though not manufactured since 2006. Audio Note bought huge quantities of the, huge. Where is Trump. He can say HUGE better than me. lol
I am glad I have a pretty good stock of them but I still use them carefully and pull them from things I no longer use.

Yeah, my best supply is in old gear I'm not using. I have some old Sony ES boards from old CD players loaded with BG's. My parts cabinets have a few, but I pretty much quit doing mods a few years back so when BG went under I really didn't stock up. I really wish I had stocked up on the little .1uF NPs if nothing else, those were/are magical little caps. On an Amazon thread I responded to an "electrical engineer" who claims expensive caps are a rip off. I don't blame him, that's what I used to think... Anyway, Audio Note gives nothing away. I might think about rolling my own before paying AN prices. You could try buying rubycon caps, disassemble them, add some graphite, reassemble them, and see what I get... I don't believe that's even illegal as long ASD it's for personal use.

in the paper and it is a difficult process form what I have read. AN is very expensive. I stocked up on mine while still available and while some were actually on sale. I mostly have the non polar, as that is what I like best. Then often I do a dual non polar with the outer foil to the inner in parallel. You get almost no inductance and the esr is just about gone.

I used to do that all the time myself. Some argued against it, but I thought it sounded slightly better so I used it all the time. Perhaps the process of impregnating the paper is what is protected. I suppose you could pull up the patent and go from there. You may want to ask a lawyer, but I suspect that no one would care as long ad you are not selling a product or a service. The trouble you would have to go through to make a few caps would make it far too laborious for anyone to economicly profit from it.

it. If nothing more, you are increasing the capacitance and depending upon where you are doing this, that normally isn't a bad thing. I can measure the decrease in ESR with an expensive cap meter I have and inductance is reduced as well. Seems good to me. :^)

I know, but folks just want to argue I suppose. They want yo know it all, to be smarter than test equipment, etc. I forget the exact name assigned to the configuration, was it super e or some such? Anyway they would claim the theory had been disproven. Math and physics supported it, my listening supported it, so rather than arguing with them, I just ignored what they said and kept using it. One of the first things that was harped on in boot camp was that "Opinions are like anuses, everyone has one and they all stink." They may have use more pedestrian/colorful language to described the anus...

Super E configuration. Yep, used it a lot. Less now since BG's are something I am frugal with.

One thing I never did a lot of was testing resistors. I figured out quickly that sand cast resistors are crap. I replaced them with Mills, but was wondering for high wattage applications which ones you prefer, assuming you have tweaked crossovers. I think many really like the gold Dales. Of course the list is nearly endless. Then there is an outfit in Texas I have heard of who talk about nude resistors for audio if my memory has it right. Have you tried many power resistors?

John PA-
did you find an SACD player?
Very cool stuff guys.
You are the MAN! Lou.
