Currawong Posted March 30, 2009 Report Share Posted March 30, 2009 This is definitely on my list of projects, along with the CTH. Quote Link to comment Share on other sites More sharing options...
Nebby Posted March 30, 2009 Report Share Posted March 30, 2009 x2 on that. I fully support what the TWP guys do but there are times that I wish they would stick with a design for a little while longer and not immediately jump to the next, newerbetterfasterquicker model. x3 on that. I'm looking forward to playing with one. Quote Link to comment Share on other sites More sharing options...

Beefy Posted March 31, 2009 Report Share Posted March 31, 2009 This just in... Nice! Would love to see a schematic, to work out how things are different from the old Buffalo...... Quote Link to comment Share on other sites More sharing options...

naamanf Posted March 31, 2009 Report Share Posted March 31, 2009 Being a sucker I am sure I will end up picking one up to give a whirl. Quote Link to comment Share on other sites More sharing options...
naamanf Posted April 4, 2009 Report Share Posted April 4, 2009 $469 for the board and $549 with power supplies. Quote Link to comment Share on other sites More sharing options...
Hopstretch Posted April 4, 2009 Report Share Posted April 4, 2009 Already sold out or not yet released? Quote Link to comment Share on other sites More sharing options...
naamanf Posted April 4, 2009 Report Share Posted April 4, 2009 I would say not yet released. They usually let people know ahead of time when they will go on sale.. Quote Link to comment Share on other sites More sharing options...
Augsburger Posted April 4, 2009 Report Share Posted April 4, 2009 $469 for the board and $549 with power supplies. Naaman, You mean with the new power supplies they were working on since Christmas right? Different than the IVY ones? Quote Link to comment Share on other sites More sharing options...
naamanf Posted April 4, 2009 Report Share Posted April 4, 2009 It looks like it's the older PSs. No idea when the newer Placid PS will be available. Quote Link to comment Share on other sites More sharing options...
Beefy Posted April 4, 2009 Report Share Posted April 4, 2009 Naaman, You mean with the new power supplies they were working on since Christmas right? Different than the IVY ones? IVY is their active I/V and line stage. The new power supply has been in development since WELL before Christmas. Russ canned it temporarily because it worked but didn't behave very well. Though by the sounds of it, the new Buffalo has fairly substantial on-board voltage regulation...... I'm not convinced that you will need anything better than the LM317 based regulators they currently sell. Quote Link to comment Share on other sites More sharing options...
swt61 Posted April 5, 2009 Report Share Posted April 5, 2009 So is this new Buffalo going to require an Ivy or Counterpoint to sound it's best, or is that built in to the new board? Quote Link to comment Share on other sites More sharing options...
Beefy Posted April 5, 2009 Report Share Posted April 5, 2009 All built in. Quote Link to comment Share on other sites More sharing options...
n_maher Posted April 5, 2009 Report Share Posted April 5, 2009 All built in. Just IVY built in right? I found that choice odd given all of the positive stuff that Russ had been posting about the Counterpoint. Quote Link to comment Share on other sites More sharing options...
naamanf Posted April 5, 2009 Report Share Posted April 5, 2009 I think the reason they went with the Ivy II on the initial B32 is because it gave them better #s since everything was on one board. The counterpoint would be on option on the second B32 board that allows more flexibility in configuration. Oh what to do. Quote Link to comment Share on other sites More sharing options...
Beefy Posted April 5, 2009 Report Share Posted April 5, 2009 Just IVY built in right? I found that choice odd given all of the positive stuff that Russ had been posting about the Counterpoint. Heavily updated IVY. Counterpoint is a funny one. Russ likes it, but I think that the design is a bit finicky. He still seems to worry about turn off thump and DC offset. I think the reason they went with the Ivy II on the initial B32 is because it gave them better #s since everything was on one board. The counterpoint would be on option on the second B32 board that allows more flexibility in configuration. Yep. We can't forget that there is a second DAC-only tweakers board coming that will allow the use of IVY II, Counterpoint, or any other I/V stage the user desires. Oh what to do. I'm sticking with my existing Buffalo Quote Link to comment Share on other sites More sharing options...
AlanY Posted April 5, 2009 Report Share Posted April 5, 2009 Does Twisted Pear use separate analog and digital ground planes? It's hard to tell if they do. From the schematics of the Opus and original Buffalo it looks like the digital and analog grounds are shared? Quote Link to comment Share on other sites More sharing options...

swt61 Posted April 5, 2009 Report Share Posted April 5, 2009 So $549.00 includes most everything needed, save for case and connectors? Seems like a pretty decent deal to me. I'm assuming that if I desired multiple switched digital inputs I could add the S/PDIF 4:1 MUX/Receiver Module? Quote Link to comment Share on other sites More sharing options...
Beefy Posted April 5, 2009 Report Share Posted April 5, 2009 So $549.00 includes most everything needed, save for case and connectors? You will need power transformers as well. I'm assuming that if I desired multiple switched digital inputs I could add the S/PDIF 4:1 MUX/Receiver Module? Yep, that is pretty much it. You should be able to power the MUX from the second channel of the LCDPS. You can also add optical and USB receiver modules with no worries.

AlanY Posted April 5, 2009 Report Share Posted April 5, 2009 NFI. I can normally follow a schematic OK, but the original Buffalo schematic bakes my noodle I think they're following Guido Tent's advice here: http://www.tentlabs.com/InfoSupport/page35/files/Supply_decoupling.pdf and not separating the digital and analog ground planes. This goes against pretty much every suggested layout by every DAC manufacturer, but Guido may still be right. I wish there was some good resource for this.

Might be worth your while to ask Russ in the Buffalo thread on DIY Audio for confirmation. I am sure that he will be more than happy to give you a definitive answer Quote Link to comment Share on other sites More sharing options...
