Congrats Shaun, I really envy you (in a positive way, of course). What are you going to plug the Teleporter into? the WaveIO or a desktop player? A cheap universal player like a 2nd hand Denon would be a great choice.

Hi Alex yes that looks like a nice piece of kit and good value for what you get As you say good for the non DIY person but even they could have a go at the Buffalo with a little help. but the big difference with the buffalo is the ability to try different PSU combinations. from what I've read the quality of the PSU makes a large difference to the resulting sound quality. Hi Phil hey i was trying to find that thread but gave up after a long search. the BuffaloIII is to all intents and purposes the same as the B2 but with more IP options and now takes TTL signals directly. Also improved Trident shunts pretty much as standard (wider bandwidth OP-amp). also improved board layout and grounding scheme. will it sound better? who knows but people have reported an improvement with the new tridents fitted to the B2. thanks for the good luck and i think that i may need it. Hi Javier yes i intend to use the WAVEI/O board with the Teleporter and will have a go at the following method. PC-WAVEI/O (0.5M USB cable)-Teleporter (converts to LVDS)-6M LAN cable (CAT5e)-Teleporter (converts back to I2S)-BuffaloIII. so the idea is to keep the USB connection to the WAVEI/O short (good for Lorian's board from what I've read on the DIYAUDIO thread). then have the I2S connection to the Teleporter short (I've managed 3cm connections) the Teleporter converts to Low Voltage Differential Signals for data,Bus clock and word clock. and then back to I2S at the DAC.( i think i have that right but it's still all pretty new to me ) from what i've read on TP's web site the ground betweem WAVEI/O and teleporter remains unconected which gives isolation between IP and OP Teleporters but i've not tried that yet so i don't know for sure. Is it going to work? haaaa I've not a clue but the benefits of keeping the WAVEI/O near the PC and the I2S connections short at both ends look worth the time to find out. pictures to follow. take care All

I find it a little odd that TP have introduced a 3rd version of the DAC, but are still using a PCM2707 USB receiver chip. The 16/48 PCM2707 is well and truly old hat now.

So far all this about the 9018 is based around stereo. Have any version or variant builds that can do multichannela as well at it's maximum of 384/32 thru all input types that we can name? The 9018 is actually designed for multichannels and can't do multichannel in most cases and that's the surprise. Only the Oppo 95 varaint can do multichannels. If you guys have seen any multichannels version in the internt of what I had written I will be extremely interested. But this doesn't mean the stereo version I'm not interested. Let me know the link if you have seen it. Have fun building your Buffalo 3, Shaun! I envy you too.

Blazing that trail again Shaun I hope it meets expectations. To save me actually reading through all the bumpf, are there any basic/major differences between II and III or just a case of refinement?

Let me know the link if you have seen it. Have fun building your Buffalo 3, Shaun! I envy you too. Hi Chong there are a few multichannel builds on the BuffaloIII thread using all 8 IP and 8 OP. looks like the tricky (expensive)part is the number of I/V boards needed and associated PSU's. I think that facilitating multichannel was one of the reasons for the MK3 update and some people seem to have grasped that aspect pretty quickly. I'm just doing plain Jane stereo. no envy required I've no guarantee of having a working DAC. Hi Xerxes Yes indeed that USB board is still available but as Javier mentioned an Xmos based module is in the offing and possible something a little different judging by today's conversation on the TP USB transport thread. Hi Javier that DSD link looks interesting as the Teleporter is good for that format also. I'll be taking a closer look at that one later. but i may need a translator when it comes to implementing it. I'll take a look and see what i can make of it. take care

Hi Chris i think it's more like lurching along hoping for a good outcome rather than blazing a trail. if it works when i come to switch on it will meet my expectations very well OK the differences between 2 and 3. well I'll let Russ White do that as it's his baby www.diyaudio.com/forums/twisted-pear/188941-buffalo-iii-flexibility-without-compromise.htmlfirst post tell pretty much all take care

I'm just doing plain Jane stereo. no envy required Oh dear, and I'm supposed to be Tarzan it seems now? So don't envy me as Tarzan as I don't like that role. Just imagine having to Oops, I mean this ........... Early morning blues! every now and then. Yeah, on top of swinging amongst the monkeys. I've no guarantee of having a working DAC. Er, how can that be with so many owners around? They will make sure you are up and running too. Well, at least not like me as the supposedly Tarzan.

Hi Chris I think you will find that the main selling point for the basic later version is it's ease of construction, not improved SQ. Allan Pagan will be able to provide further info on this as he has built one. At the time I heard Allan's, it was still a little behind the full on SC DAC in overall SQ. I would be interested in doing a further comparison against Allan's B3 now that he has had a chance to further refine it's PSU area. Regards Alex

Hi Shaun I did say "the basic later version" not the value added version you are making. TBH, I thought Allan's build using mainly TP shunts etc. was a little disappointing. A PH reg or 2 ,or a few JLHs may completely transform it . Leo could have a lot of fun extracting the best from it! We were listening via Allan's very nice little media PC into the Class A too. I wouldn't mind one of those, if I could afford it. Regards Alex

I wouldn't mind one of those, if I could afford it. Regards Alex Hi Alex i have a hunch that the standard build that I'm trying will leave a little room for improvement.but without having a listen it's hard to say. so I'm trying to see it as a starting point to further work later on the reg front. i must be one of the few people on the planet DIY wise that has not heard the 9018 buffalo's but i did hear the original with tube OP and was impressed. the MK3 Tridents are a rework of the MK1 and use some nicer components but it would have been nice to compare the two. JLH,Salas,PH regs are all on the list to try out after i have a grip on the sound as the designer intended. TBH I'm not expecting much SQ wise (as it avoids disappointment)and it will make an interesting Comparison to Will's PK DAC with Salas shunts which has impressed me greatly. so getting it working will be a result in itself and then the fun can start. I'm really hoping that Mr Pagan and others who have experience of the 9018 chip will join the discussion as that will be so much more interesting that a i did this and then that thread. so if you bump into him take care

Hi Guys, Sorry I've been absent for a while, had a lot on me plate . Anyway good luck with the build Shaun, I'll do my best to help if needed so just give us a shout on here or whatever. I actually have removed the Legato board for now and reverted to the old original IVY, I don't like IVY III tbh (various reasons) . Theres a few things I want to try with Legato when I get around to it. These dac chips are extremely high spec, its just a shame its an arse to get the best out of them

These dac chips are extremely high spec, its just a shame its an arse to get the best out of them Hi Leo How's it going yes I'm just plodding along with the standard build at the moment. i must say that the provided kits are very well put together with everything labeled and bagged up. nice quality boards also which makes for a nice stress free build. so far i have the Placid HD, Placid HD BP and Legato built up with no real problems. both PSU test OK (unloaded) but I've not put a load on them yet so fingers crossed on that. I've also built up the Teleporter WAVEIO front end which powers up without smoke so I'm hopeful on that, it will be interesting to try the MK3 tridents which some have been reporting as an improvement compared to the old ones SQ and reliability wise. but who knows on that front so now onto the DAC board and well i would have been a little put off by those SMD 0ohm links that need to be soldered but hey I've had a little experience with that (thank god for Wills PK DAC) so I'm cool about it. oh yes while I'm thinking on it you changed back to the IVY/III from the Legato. which version where you using? the 2 was said to be a little warm but slightly bass light compared to the IVY. just wondering on the reason for the swap back. I'll post some pictures soon. yup work needed to squeeze the Pear but that's all part of the fun. all juice no pulp take care

I had original Legato but converted it to latest spec . Not sure if I like it tbh but we'll see, theres a few things I want to try yet. I couldn't get on with IVYIII, for me it sounded quite forced and proved tiring after a while so I wired up the old IVY version on the smaller pcb. Would be interesting to try alternative output stages.

Mine is using the trident 2's TBH I didn't know about instability problems.... I'm still thinking about used the PH regs for this. Allan

Havn't done anything to the dac for a while.. Hi Alan nice build you've gone for the 3 power supply max out on the Legato. mmm i'd be most interested to hear if that made a difference SQ wise in your opinion (makes the Placid HD BP run a little cooler though). Also you look like you have the headphone option running. so any thoughts on that would be helpful as i may build that in for reserve use. i think that you may have the Trident 3 in your DAC as the MK 2 never made it to production as it was deemed to be expensive.I'll be starting with those and listening for a while while the bank balance recovers Hi Leo yes i did read that the Latest spec Legato is brighter sounding than the MK2 but without the two to compare it's hard to say. alternative OP stages hell yes and plenty to choose from. i know that i should not but ;D ;D I'd quite fancy trying the unballancer circuit. it looks easy enough to bread board or P.P so i may give that a go.I've built a few of his circuits and they usually work well. also transformer coupling may be interesting to try but i need to have the thing working to start with. looks like there could be an easy option for sync-ing the WAVEIO to the DAC also which i may try at some point. and of course the PH regs. for now I'm going to be more than happy if it plays music at some point and interested to hear if the sound matches what I've read. not all reports are great but i suspect it's going to be another Marmite thang. so SMD on the DAC board Tomorrow. i must dig out the glasses take care
