I agree with SAKAHARA, although I am still getting pretty decent sound with EVO. I had to go thru 9 levels of Technical Hell, being led by the Prince of Darkness himself with the loure of so-called CONVENIENCE! You buy a High End CDT, and you get a real paper Manual that treats the Customer like an idiot (Thank God!). With PC Audio, everyone expects you to already be a Rocket Scientist, and then they won't even waste their time on you if your not! The difference is Night and Day, CDT-loads of Customer Support, PC Audio-vacuum of Customer Support. Contact Manufacturer CDT, and get immediate response to resolve problem. Contact PC Audio Manufacturer, and be deflected to Customer Forum to solve problem. What the hell does the Customer know about the Product, he didn't Manufacture it! Around and around you go getting mountains of misinformation, without any Quality Control. I would say that I am batting 50/50 with Forums, half the time its accurate helpful information, the other half is nothing but Gross Conceptual Error. Substituting Amature Customers for Trained Customer Support Staff will be PC Audio's Downfall. It is just an attempt to save loads of money off of the skin of the Customers. You may not agree, but certainly PC Audio has a reputation of Customer Support that Sucks, regardless if it is well earned or not! "If you don't like it, don't buy it"! Well, if you want to replace all other forms of listening to Audio with PC Audio, its Customer Support has to measure up! People are going to expect the same Customer Support that they are used to getting with other competing Music Sources. They are not going to step w-a-a-a-y-y-y down into the gutter of PC Audio Vacuum of Customer Support. There is nothing CONVENIENT about this! It costs the Customer valuable Time, and Money, to do so! The real threat to PC Audio, is more and more people become painfully aware of this! SAKAHARA won't be the first, and he certainly won't be the last. Who exactly is responsible for letting him down, who? Accountable Customer Support Agent, what Customer Support Agent? Is PC Audio simply the lazy Manufacturers Music Source, to replace all other accountable Music Sources? Gee, who can turn down a deal like that! Be still my aching Heart! Really getting sick and tired of the excuses for PC Audio Customer Service. Also getting sick and tired of the attitude that everyone just has to suck it up! No, we don't! We can, and should demand better Customer Support, regardless if you buy PC Audio or not! Otherwise, take half off the price if you want to take cost of Customer Support out of my wallet! That goes for any Product, PC Audio or any other competing Music Source! PC Audio WILL serve me, because I sure as hell am not going to serve it! Refer to your Emacipation Proclamation, if you can't figure it out! I am Human, and the Machine serves me, NOT the other way around! The alternative isn't something that, "don't buy it if you don't like it", are you kidding me? As if Humans serving Machines is even a serious option! |
There is apparently some miscommunication here. My apologies for the missunderstanding here. I have been buying High End Audio for over thirty years. In that time I have owned Theta Data/Theta DS Pro Gen. IV Processor with Theta's Single Mode Glass Fiber optic connector. I have owned Mark Levinson No. 37 Transport/ No. 360s Processor with AES/EBU Digital out and DAC with fully Balanced Topology-not just another AES/EBU Input. PS Audio makes a Transport/Processor known as the Perfect Wave System that utilizes an I2S connector. Exact same as Audio Alchemy? You would be wrong! PS Audio reworked the I2S when they developed the Perfect Wave System. These Inputs do NOT sound the same, I have heard them, and I have owned them. It would be theoretically impossible, based on simple Electrical Theory. that they would even sound the same. All Fiber Optical Connectors have to go through two conversion Stages, one converts Electrical signal to optical signal, another converts optical back to electrical. This gives good Electrical isolation between Source and Processor, but requires Digital Signal pass between two conversion stages. AES/EBU does NOT pass through the same two conversion stages, and you lose the Electrical isolation. Basic Electrical Theory would deny that you could even concieve of recieving the exact same signal from both. Based on simple Electrical Theory, it isn't possible. They are simply not the same process, hell they are not even close. Yes, I DO hear a difference which verifies what simple Electrical Theory tells me. I have not owned these Transports/Processors in a Vacuum, others have owned them as well. They also report hearing the same thing, variation in Sound Quality based on the type of Input. Reviewers have been reporting on these differences (Stereophile, The Absolute Sound...etc) and the compatibility with other equipment based on different Inputs for well over 30 years of Reviewing Digital Equipment. All Digital Outputs (CD) sound exactly the same has been the longest lie that has ever been foistered on the American Public. Now it is being ressurected with PC Audio despite 30 years of experience to the contrary. It would be impossible to get so many of them exactly the same, Electrical Theory says it can't be done. Nothing in this Universe is THAT perfect, unless you live in an Empirical Audio Universe where the Earth is concidered perfectly flat! Of course you don't understand how a round Earth works, the same way that you don't understand how different Inputs could affect Sound Quality. Explain then, how SAKAHARA can't seem to get anything that sounds satisfying with his System. By your standard, the Sound Quality he recieves is nonsense! "The only variable is the S/PDIF coax cable or AES/EBU cable used"! Well there you go SAKAHARA, according Empirical Audio, its all in your head. According to them, you just have the wrong cable! You are looking for another Converter/Processor because you know you have a compatibility problem. They say pretend no difference exists. I gave up pretending when I was 5 years old, and I am not going back! Stop trying to rewrite the laws of Physics, and stop trying to rewrite 30 years of historical experience with Digital Audio. All CD Players sound the same, all PC's sound the same, all Inputs sound the same, what is the next Wives Tale you want to sell the American Public? You would have to make a concerted effort to even try and make them sound the same, and you would still lose! Stop playing God, your not very good at it, and besides the position is already taken. Perfect in every way? Based on Human Inperfect Manufacturing? Now who is talking Nonsense? You think it is that Perfect? Don't make me laugh! In your Dreams, maybe!

Sakahara-You only get 1/2 of it. Too many variables to just guess, there is a way to be reasonably certain. Contact Reimyo, look up past Reviews of DAP-777 on The Absolute Sound/Stereophile Websites. Reviewers have a tendency to try ALL Inputs to find Sweetspot Input. You can contact others who own Reimyo DAP-777 here and other Forums on Audiogon. Try to find someone using DAP-777 with PC Audio, or CDP, and has tried various DAP Inputs. Contact the Dealer who sold you the Reimyo, he probably has experience with other Reimyo Customers, and what works best for them. This can either be CDP or PC Audio Input. The more info the better. Need to really research the DAC to determine best Input. So many who don't, end up buying $1790.00 Converter which should sound great; but, doesn't due to Compatibility issue. Compatibility issue can be just using alternate non-optimized Input on DAC. Not the Converters fault. Any Input can be the optimized Input on DAC, the other Inputs not so much. Design of DAC can be made to sound best around BNC, different design around COAX-SPDIF, different design around OPTICAL to sound best with these. You want a DAC that sounds best with ALL Inputs, be prepared to shell out $10,000.00 for other Inputs you will never use. Many Inputs on many DACs are just Window Dressing pretending to be Swiss Army Knife, which does sell alot of DACs. Other Inputs will function, but not nearly as well. It is whats under the hood, that corresponds to what is plugged into the back that counts. Some DACs have no problem dealing with Switching Mode Power Supply from Computer and Audiophile Grade Digital Sound Card. Some DACs have Switching Mode Power Supplies themselves, their Power Supplies designed robust to reject SMPS noise. Other DACs desperately need Power Supply isolation from PC via Analog self Powered Converters. So even concideration of the Power Supply of the DAC is a critical factor with PC Audio. IMHO, all of these missmatches are the true cause of radical differences in the positive/negative results with PC Audio. Please don't ask me to drag the PC Software into this as well. Five times more possible combinations means five times more opportunity to get it wrong. Yeah, the connections will fit, they were designed to fit, but don't assume that they were ALL designed to sound the best simply because they do fit. This is one of the greatest misconceptions of all Audio, and five times more complex with PC Audio. Know your DAC to minimize variables, you will know yourself, and you will know for certain. Things suddenly get allot easier after that! |
Lokie-Spending $1,799.00 on a Converter, that would normally sound great; but, sounds awful due to compatibility problems with DAC IS a waste of time and money. Turning this into Russian Roulete, or Crap Shoot is never more simple, and definitely more complicated. There is absolutely nothing wrong with any one of these Converters, except they will benefit certain DACs; but, not others. The critical factor is the design, and type of DAC, the optimum Input based on that design, not to mention the Power Supply for the DAC. All DACs are nowhere near the same, and not all Converters will behave the same with all DACs-no matter what the price or quality. Some get best Sound Quality with Firewire, others with USB, some with Fiber Optic, Wireless, SPDIF, BNC, AES/EBU. They can't be all optimized for best sound quality for all DACs, that would be impossible. The only deciding factor here is the design of the DAC, and the optimized Input based on that design. This will limit what Input to use, limit what Converter to use, and which type of connector. Process of elimination doesn't make things more complicated, guessing in the dark does! Try Halide Bridge before you buy, if you want to make things simple. If you even want to make things more simple, do a little research on your DAC. Wonderful thing the Internet, saves time and money! Do a search on Reimyo DAP-777, who knows what you might find out. Knowledge is Power, lack of it is never simple! |
Only thing off track, is complete lack of adequate directions and instructions from PC Audio Manufacturers. If you really want to limit your Market to only Nasa Engineers, there is only so many of them. Your Market isn't going to be worth squat! Don't PC Manufacturers test their Equipment/Drivers in current Operating Systems? They advertize compatability-based on what? If the actual PC Manufacturers don't know how to install the damn things, how is a bunch of Customers in a Forum going to figure it out? They owe it to their Customers, to get off of their lazy butt and figure it out! What is the point of manufacturing something that you have no clue as to how to install? Fifty percent failure rate is unacceptable, time to get results oriented with PC Audio Manufacturers (way past due)! |
Sakahara-Internet search produced review of Reimyo DAP-777 by Positive Feedback Issue 34 in 2007. Review includes both Reimyo DAP-777 and Reimyo CDT-777, both Solid State Units. It looks like the DAP-777 has a volume control, couldn't quite tell, reviewer didn't cover this. Reviewer also didn't cover what DAP-777 can decode (24/96, 24/192...?) Presume that you know this already. CDT-777 utilizes Philips CDM-12 Drive, and only has Co-axial Digital Output. DAP-777 has Optical, Co-axial, BNC, and AES/EBU Digital Inputs. DAP-777 also has Balanced, and RCA Audio Outputs. Transport sounds like it was designed specifically to go with Reimyo designed DAP-777, Reviewer didn't try with other Transports and DACs. It sounds like you already have. Have you ever owned Reimyo CDT-777? Usually, Transport and DAC are designed by same Manufacturer to go together. Trying DAC with other Sources might work well, but usually not as well as designed Transport. Recommend taking DAP- 777 to local High End Store, and trying it with various Transports utilizing various DAP-777 Digital Inputs and various Analog Outputs. Balanced in, balanced out usually sounds best; but, listen and verify with your particular DAC what sounds best to you. That Input is more than likely going to be your optimum Input from PC/Converter. Manufacturer is listed as COMEBACK CORPORATION, JAPAN. Web Address: www.combak.net. Try and contact them by E-mail to get best recommendations for PC Audio/ Converter/ type Input for DAP-777. Importer Info: MAY AUDIO MARKETING, INC. Tel: (800) 554-4517. Web Address: www.mayaudio.com. E-mail Address: mayaudio1@aol.com. Contact Importer and try to find out what most Reimyo Customers use for PC Audio and their DAP-777. Try searching Audiogon Forum for Reimyo DAP-777. Find other DAP-777 owners to see what they are using. You only have $1800.00 to lose; but, if it is the right device for your DAC, atleast you will know. |
I have been talking with Steve N. from Empirical Audio. He is an experienced Audio Engineer with extensive knowledge on PC Audio. Where I disagree with him, is his conclusions of 30 years of Research, development and experience in designs of other Transports and DACs. I suppose that this is nothing new since every Audio Engineer has his own idea of how to design equipment, usually dismissing lessons learned by others earlier. He appears to be successful at what he is doing, and I wish him further success. I just have an honest disagreement about some of the conclusions that he has drawn from the last thirty years of Digital Audio Development. He does dismiss many Audiophile beliefs, be they based on personnal experience or not. I get a little wary when someone tells me what I am supposed to be hearing, when it conflicts with what I am actually hearing. Everyone is entitled to their opinion, based on their own personal Audio preferences. The problem is when we dismiss someone elses Audio preferences by calling them, "Total nonsense", when after all, they are nothing more than just a difference in preferences. I have a tendency to over react when faced with intolerance, by some, in PC Audio over different Audio preferences by many. Audio will ALWAYS have room for different opinions, regardless if it is PC or CD. When this stops, Audio will no longer be a Hobby worth pursuing. I would like to think that this can be avoided with PC Audio, but everyone (including myself) needs to just loosen up a little bit. Would really like to enjoy this Hobby once more. |
SAKAHARA-M2Tech Support only understands Italian. You have got to send it to them in Italian. How good is yours? I have the M2Tech EVO, and you have to have EVO plugged into Computer and powered up prior to installing Driver. Without it, you are making configuration changes in reference to an attached device that MAC can't see. Could be reason OS X is acting flaky. Still having problems, try another USB Output. Verify Power light is on with EVO (make sure it is getting power). Eating dirt here, and being grateful for that dirt! Yummmm! |
Excellent Decision- Tvad? After investing money in PC Audio only to have the wheels fall off for the upteenth time due to lazy Manufacturing! Whatever you do, DON'T you dare try to demand that PC Audio Manufacturing get its act together! Pay no attention to this horrendous accident-Folks! Just move-on! Move-on! "Just crawl back into the Ship, and await in the dark so you can't see what is eating you"! Is that the idea, Tvad? I know one thing, when the dying starts this whole psycho family of PC Audio is just going to just rip itself apart! Don't you cry for PC Audio....don't you DARE! |
Sakahara-I am currently using Hiface EVO between Windows 7 PC and Space Tech Labs DA-64XT Super Vacuum Tube DAC via AES/EBU Digital Input. Every DAC is particular to type of Input from PC, as well as Design of DAC, and its type of Output Stage, even the DAC's Power Supply. My DAC uses Tubes, which are highly vulnerable to PC Switching Mode Power Supply. This is only particular to my type of DAC, not relevant to any other DAC. Each DAC is going to have its own particular needs from PC Audio, based on its design, and the type of Input the DAC is optimized for. There is no, "ULTIMATE", Converter/Input for ALL DAC's with PC Audio. All DACs are different, and not all Inputs will perform the same. Because of this, there has been such a mixed bag of results with; Firewire, USB, AES/EBU, Toslink, Glass Fiber Optical, Wireless, SPDIF, Asynchronous, Non-Asynchronous, Soundcard based on PC Switching Mode Power Supply, External Converter with separate Power Supply. You are just not going to be able to design a DAC that sounds wonderful with all of these. I would contact Reimyo, and find out which Digital Input performs best with DAP-777 with PC Audio. Was DAP-777 designed to sound best via its USB Input, AES/EBU, or whatever Inputs it utilizes. Will DAP-777, based on its design, sound better with Digital Soundcard or External Converter? Don't assume anything! With PC Audio, compatibilty is more critical with three more times as many different types of Inputs. Others can defer, I will still say feed DAC what it was designed to be optimized with for maximum performance. This will be different for every DAC, because each DAC IS radically different. Upsampling, Non-upsampling, Oversampling, Vacuum Tube Output Stage, Solid State Output Stage, Fully Balanced Output Stage, Balanced Input, Vacuum Tube Rectified Power Supply, Solid State Power Supply, Switching Mode Power Supply, Analog Power Supply, and this doesn't even include the DAC Conversion Rates and different types of Inputs. If Reimyo DAP-777 is your DAC of choice, then design your PC Digital Input around your DAC's design. Then try to choose a Converter that works best with your Reimyo DAC. Try a friends $1200.00/$1790.00 Converter first to determine Compatibility with Reimyo DAC. Try a High End Store with MAC, DAP-777, and various PC Converters to determine best Compatibility. |
Nice GCE Audioengr. I already gave multitude of variables in my Statement, unless you can't tell the difference between a S/PDIF coax cable, Toslink, and USB Cable? Are you trying to say, in your Universe, that Firewire/BNC/ ST Glass Fiber/Wireless/Toslink don't exist? The only thing that does is S/PDIF coax and AES/EBU? I suppose you fancy yourself as the center of this imaginary Universe. Perhaps the other Connectors fell off of the edge of your Engineered Flat Earth Design. You are comparing Apples to Apples and claiming no difference. I am comparing Kiwi to Watermelon, and can't understand how you can possibly miss the difference! Optical goes thru two conversion stages, electrical to optical, then optical back to electrical. Its like sending your Digital signal through a meat grinder, and expecting a T-bone Steak to come out the other end. This is the same as Co-axial or AES/EBU? Only if you were the Son of God! So step off of your mile high pedestal, you are nowhere near that Holy! If you still think that you can walk on water, I would love to see that! What kind of Empirical Audio Engineering Nonsense is this? Go back to basic Electrical Theory 101, Electricity doesn't quite travel through Glass or Plastic fibers quite as well as it does through Copper Wire. You are aware of those two little conversion stages in the optical medium, right? You didn't really think that those Optical Fibers were passing live current more efficiently did you? Hey, hey, what about a DAC with a USB Input? Gee, Professor, "the only variable here is the S/PDIF coax cable or AES/EBU cable used"-huh?! "An async USB Converter with low jitter will improve the Sound Quality of virtually all DACs", does that also include DAC's with USB Input too? Gee, Audioengr, I have nipples-can you milk me too? |
One question, Davide256- why can't SAKAHARA (or yourself) get help from the actual Manufacturers of the MAC/PC Products? Why are Customers being forced to seek help from those who never Manufactured or Produced these products, WHEN it comes to PC Audio? Rely soley on other Customers to resolve issues, and keep your fingers crossed that it is accurate information? Well, THAT it is not exactly working out for SAKAHARA, and he is not alone. Who does he turn to now? PC Audio has a Disease, and its spreading like Cancer-" Would you mind if I kindly ask you to take your Silly-___ problem down the Hallway "! What has started out as a saying, has become the Holy Bible of PC Audio Customer Service! PC Audio Community will crucify anyone who dares blasphemes against PC Audio, constructive criticism or not! Manufacturers skinning the Customers alive, if not taking a pound of flesh out of their hides, when it comes to PC Audio Customer Support. No, you just don't have the proper Tools to do the Job, when it comes to making PC Audio a real sustainable thriving Industry. The ad-libbing that struggles on, is laughable! If it was any other Product, say your Car, would you even tolerate being forced to use other Customers as the ONLY source of resolving problems with your Vehicle? Manufacturers on permanent vacation! You would be pulling your hair out by the roots, and you know it! People have a certain expectation with ANYTHING they buy, of a certain level of Customer Support. When it SUCKS, people complain, because that is what they do! THEY have to spend the extra valuable Time, and Money, to compensate. Why is PC Audio the ONLY Retarded Stepchild exception to these Rules of the Market? AIN'T-THAT-SPECIAL! Fine then, cut the Price in half, and everyone will be happy. I am getting sick and tired of PC Audio Manufacturers having their Cake, and eating it too. PC Audio Customers forced to eat dirt, with a PC Audio Community physically whipping them into being grateful for that dirt! PC Audio marketing model spreading to other Industries, Car, Refrigerator, Washing Machine.....etc? AHHH...NO! "But its more convenient"- HELL NO! Customer Support isn't necessarily that great in other Industries, but atleast you are not castrated for complaining about it! "If you don't like it, don't buy it", isn't used as a fig leaf, because it won't cover EVERYTHING you buy! That boat will not float. "If you don't like the boat, don't buy it". Sure, if I survive by bailing water, if I don't drown, I will be sure to get right on that! |
In simpler language AUDIOENGR, it is Operator Error, NOT lack of adequate Manufacturer Instruction that is at fault-is that it? Not buying it! If Manufacturer is advertizing USB Converter/Driver to be compatible with Windows 7 or MAC OS X System, Manufacturer never tests these Devices in these specific Operating Systems to make sure they work? What do they do, just cross their fingers and hope for the best? Customer becomes the Guinee Pig? If you drove a brand new car off of the Salesman's Lot, and the wheels fell off, I don't think that you would be so gracious! Especially if Salesman ran up to you waggling his finger in your face, "Whooops....must be Operator Error"! You will have to forgive some of us for not being as gracious with PC Audio. Some of us want to break that finger off, and shove it were the sun don't shine. If that just makes us uncivilized brutes, so be it. Just how many times do the wheels of PC Audio have to come off, before we learn anything? I have learned one thing, Operator Error is a piss poor excuse for lack of Manufacturer Prior Proper Planning in Adequate Instruction for the Proper operation of any Device. In simpler language, that boat won't float no matter who is operating it! What, the Operator simply didn't bail water fast enough, so says the Boatmaker? How convenient! |
