  1. Hi Guys Heard them myself. All I can do is heartily agree with Kdoot. Thanks Bill
  2. Qualified though. A GOOD one. I have found mediocre ones simply do not cut it. My first experience with pre magic was the legendary AR10 - that's when my views did 180% about face. Thanks Bill
  3. Hi Guys Looks like Mike will have a new addition to his factory set-uo - a BHK pre. Will eventually get one myself - but need to sell a lot of gear first. Will chat to Mike tomorrow about that and see what can be done. Will be going down to Mike's tomorrow anyway - have been working hard on tuning the ML5's with Rawl and there will be some trickle down to the ordinary ML5's eg Rawl has found some Cardas speaker terminals that work really well with them. Will be finalizing the first uber pair of ML5's and will see how it goes with the new pre etc. Fun times ahead - and Mike a GTG is on the way - I can feel it.. Thanks Bill
  4. Hi Guys I have a non-souped up 103 Oppo . It has the latest software, It too does funny things with some .mov files. Its obviously a bug. Thanks Bill
  5. Of course not. He should make up his own mind - but the more people that confirm by direct litening it does sound better obviously it will help in deciding - is this just commercial BS or not. I now think its commercial BS in the sense its a breakthrough - it can be achieved in other ways - but it does sound better. Thanks Bill
  6. Simpy that they confirm MQA does sound better. I think it does, Mike thinks it does, but the more the merrier I say. What the whole post above was saying is there are many ways to skin a cat, MQA is not the only way to drastically reduce the size of Hi-Rez files. But it is being pushed hard by companies like meridian with a lot of commercial clout. But can we take discussion of this to elsewhere than this thread which isn't really about MQA. Don't worry Clay is well aware of it and will ensure he Konverter keeps up with the latest trends once it has greater market penetration - its very early MQA days yet and you can already feed it from Tidal anyway - Clays DAC sounds great that way, Thanks Bill
  7. Many very knowledgeable people do, including Ted Smith who invented the Direct stream DAC. Its a perfectly valid responce. But please don't make up your mind until I get my little Explorer 2 to people like Clay, and see what they think. Just waiting for: 1, Until I get my Macbook and install Audirvna 3. 2. Mike finishes the high quality audio cable that really lifts the performance of that DAC. The truth will out - in time. I had a bit of a discussion with Ted Smith about this and got me onto an interesting piece of software I have been fooling around with: Interesting results - for example take 2xDSD which is considered pretty good high res - you can get some from here: Convert it to DXD, run it through the software, first at DXD to get the maximum frequency.and use it to find the maximum frequency of actual music. I ran Jan Gunnar Hoff - LIVING through it and its maximum frequency was a bit below 30k. Then convert it to the the sampling rate that contains the maximum frequency - I chose 176khz to be really safe and counted on the compression algorithm to take care of redundancy. Then run it through Optimfrog lossless compression which is a lot more efficient than FLAC - its amazing how small a file you get - it went from 375mb to 55mb (flac was 75mb). That's about the same as MQA. Interestingly at 88khz sampling it was 53.3 (Flac was 71mb) so the sampling frequency when you remove frequencies above actual content doesn't seem to make much difference. You could probably do it at DXD - it wouldn't really matter. So whats the bottom line other than being something interesting to do - yes - MQA is quite likely some marketing cynicism rather than an actual advance - drats - still it does sound better. Thanks Bill
  8. Good to know about 3.1 as that's how I use my Direct Stream - via the Bridge 2. Hopefully it will support the Bridge 2. Regarding MQA some people are just so cynical. The article is true - as far as it goes. Yes it can be seen as a cynical exercise to get more royalties. But it doesn't give all the technical facts: 1. Its very easy for services like Tidal to incorporate. 2. Its not lossless, but only lossy in inaudible ways I will list: The last 8 bits that store the compressed 22-44khz info are below the noise floor of virtually all recordings, random sounds below that are of not of much concern even if nothing was done. But something is done. What you do is from the 24 bits you subtract the compressed data from last 8 bits, chop it off then put in the 8 bits you subtracted. This is a form of subtractive dither and increases bit depth to above 16 bits - see the graphs below - notice how it lies about 2/3 of the way between 16 and 24 bits. Notice the following. The theoretical noise is always within about 10db of the thermal noise limit that its impossible to go below and WAY below the noise of an actual implementation such as the Explorer 2. 3. It interpolates to go from 44k to 88k, 176k or beyond. But since this is mostly noise who really cares - that is of course very lossy but since its mostly noise it represents just some more noise added in. But that high in frequency the noise added in is WAY below the thermal noise limit. So why do it? Because it reduces impulse response time which it is claimed to be audible. It's a practical solution to the problem of streaming hi res within our current infrastructure. Thanks Bill

    In a round about way yes, although much of it belongs in the capacitor GTG. For the Uber ML5's, Reference, Limited or whatever Mike wants to call it he has a couple of orders already. He had to decide on Caps. Cast were simply too expensive because you need at least 2 per speaker rather than just one as in the ML2. He had to make a decision and decided on the VSF. It was at the time cheaper than the RS and since from past experience sounded better than the RS, the VSF was decided on. BUT you must buy them in at least lots of 10 as a dealer (which of course Mike is) - which means at least 3 orders. He had two firm orders so took a punt he will get another. Hence my post about anyone wanting a pair. Since then Parts Connection has slashed the price of RS so they are now slightly cheaper than VSF. Why is the issue - is it because they aren't selling since the VSF were cheaper and sounded better, or is it they are now made in larger bulk quantities so you get economies of scale. I don't know, nor does Mike, nor does Rawl99. Our guess is they are not selling as the VSF is better and cheaper, so the price was slashed - but that's just a guess. Mike will look into it when he gets back from Adelaide ie has the price been slashed by Duelund which will indicate one thing, or is the price the same and Parts Connection is slashing the price perhaps because they aren't selling. Mike thinks the first pair of Uber ML5's will be finished end of April - maybe a little sooner. Thanks Bill

    They maybe Cast on the cheap. They are rated better than the VSF at Humble Home Hi Fi in their huge capacitor comparison: A lot of personal taste comes into it. Obbligato for example are rated highly - very surprisingly they sounded like rubbish - but who knows, they may sound great to some - certainly people that attend the GTG will find out. We would like to include the RS in the GTG and in the past they were more expensive than VSF, but recently that has been reversed, being now discounted heavily at Parts Connection, which may be saying something eg they are more of a mass produced item: BTW the VSF are not discontinued - as a distributer like Mike is you just have to get 10 or more. But rationalizations have to be made as far as what capacitors are at the GTG and having heard them was not that impressed so decided against including them. If anyone want's to bring them they are more than welcome - I think we need 2x10uf and 2X6.8 but double check with Mike if thinking about it. I already have got the Jupiter's for the comparison so think I have done my share . Thanks Bill

    Have done the comparison - a bit dry for my, Mike and Rawl's taste. But if people want them Mike will do it - BTW slightly less expensive than VSF - but not much (maybe the reverse when buying 10 - don't know - but it probably wont be much). Will do Cast as well but since you need 4 the cost - WOW. We (meaning me, Mike and Rawp99 on separate comparisons) have done the comparison of: 1. VSF Copper 2. Jupiter Copper 3. Jupiter Aluminium 4 Jantzen Silver 5. Jantzen Superior 6. Obligato Gold We did them all with and without Duelund Silver Bypass. They will be at the Capacitor GTG plus Erse and maybe others. It will be on my ML2 Limited so the comparison will include Cast. Our ordering was: 1. VSF Copper - neutral and natural 2. Jupiter Copper - nice sound but slightly bloomy - ie euphoric but not the last word in neutrality. Also more expensive than the VSF. I decided on them in my Magnesium Limited for two reasons. First the slight bloom will combat the slight coldness it has. Secodly VSF's are available only in lots of 10. 3. A tie between Jupiter Aluminium - Jantzen Superior. Not a lot in it but I preferred the Jupiter - others including Mike the Jantzen. The Jantzen is what Mike decided on in the Standard ML5 he is taking around. 4. Jatzen Siver - unatural detail and leading edges. 4. Obbligato - disgusting actually - but when bypassed acceptable All were improved by the bypass with one exception, the VSF. When using a Master Tape Machine as source they tended to highlight treble unacceptably - but that may have been something wrong with the tapes used. We did it with a simple Squeezebox as source and the silver bypass were easily better. Will be doing it with the Killer DAC as source soon. Thanks Bill

    Hi Guys Down at Mikes paying for stuff and was told the Duelunds for the uber M5's have arrived and their construction will start soon. The only trouble is you must buy the VSF copper in lots on 10 these days. Mike got 12 in so he can do three - 4 needed for each pair. My friend Kev has fully paid for a pair. Another guy has put a down-payment so he has secured a pair. If another person want's to secure a pair give Mike a tingle. Since they need to be bought in lots of at least 10 then after that you will need to wait for 3 orders before they can be built. Mike is busy, busy, busy preparing for the Adelaide GTG. Thanks Bill
  13. Audirvana 3 released That's not going to help much though - the Mac I have access to is not powerful enough to run Audirvana 3. Looks like I will have to dig into my dwindling funds (Yuk) and get a Mac powerful enouht to do it: One I have that and install Audirvana 3 will lend it to Clay and see what it does with his Dac's and compare it to a Meridian Explorer 2 I have - after I have mucked around with it of course. I particularly want to compare it to MQA via the Bridge 2 to Audirvana 3. But it will be a month or 2 before the Direct Stream Bridge 2 does MQA. At the moment, the Bridge 2 its not as good as Audirvana (or the Konverter from memory) and a Curios cable but will see with MQA - it should be out for the Bridge 2 in a a month or two. You guys will have to decide - are you happy with only Clay doing such a comparison and writing it up or is something more independent is also required? My vote goes to both - but the independent one will take a while to organize, probably at a GTG or something like that. BTW Clay is a VERY upfront sort of guy - if something is better than his product he will say so. But I know that simply because I have known Clay for yonks - others likely will not know Clay that well. Thanks Bill
  14. Hi Guys My Magnesium's are nearing completion. Decided on a couple of things that will be in the final version. 1. It will use Jupiter Copper capacitors bypassed with Duelund bypass capacitors. I actually slightly prefer VSF Copper but they must be bought in lots of 10. The VSF is slightly cheaper, a bit more neutral and natural. The Jupiter has a slight bloom by comparison but in this case may be an advantage because the Magnesium's drawback is a slight coldness this may counter - we will see. 2. Will be using Bybees directly bonded to the driver terminals. Mike is getting in two lots of the internal speaker bullet kits: Will also see how they go on the new ML5's Rawl, me, and some others are tweaking, before installing them in the Magnesium's. As soon as they are completed the comparison to the ML5 will be VERY interesting. I already think they are better than the ML2 Limited - but we will see. I have a pair of ML2 Limited at Mikes just for that comparison. The looser will be sold. Thanks Bill
  15. Hi Guys Visited Mike yesterday to pick up the Duelund Bypass capacitors for the tweaking of the ML5's with Rawl99. It was a madhouse down there - busy, busy busy. No time to even hear my new Bridge 2. But will be returning Friday to pay for it so may get another chance then - but he is so busy I am not counting on it. He will probably just put my credit card through then get back to work. Anyway he clarified what's going on with future GTG's and travels around the country with the ML5's. From the 20th to 24th of this month Mike is going to Adelaide with the pair of ML5's I posted in the ML5 thread. The Sydney GTG will be at another time to be determined. The capacitor GTG will also be further down the road - Mike is just so busy he cant set a definite date for this stuff yet. He asked me to post this and of course apologizes for not being able to post himself. Thanks Bill
