| Theoretical question about how CD's work Most of CDPs play in real time - there is no time to read particular sector again. Ripping program can access each sector unlimited number of times to obtain right data (proper checksum). Car or portable CDPs have to make up time to be able to r... | |
| Schiit Ragnarok 2 (Fully-Loaded) / Digital USB input / No optical cbob, Airport Express, that I use with Benchmark DAC3, has some small jitter (280ps) and optical connection, that is prone to convert system noise into jitter. USB interface, as long as it is asynchronous, doesn't have this problem but might inje... | |
| Surge protector Eric, I went with Furman Elite 20PFI. One evening bulbs got brighter for a moment and Furman's circuit breaker tripped. It automatically switched back after few seconds. Furman also protects from under-voltage preventing operation outside of sp... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong One more thing (as Columbo said): SMPS are not cheap. Cost of high quality SMPS has to include high cost of development. Rowland’s supplies deliver thousands of regulated watts operating at 1MHz (and components doing this are not cheap either). I ... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong Switching amp (class D) and SMPS IS the same thing. In fact class D was discovered when engineers tried to show how responsive SMPS was by modulating it with music. I would say that it should be more difficult to build good class D amp than goo... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong Class D can be wonderful but in my experienced opinion, if it has a SMPS just forget it! Even my Mac Mini music server SMPS killed the sound, it now has a linear supply.All highly rated Rowland class D amps have SMPS. When done properly SMPS is mu... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong willgolf, My class D amp was designed to be on all the time (no power switch). I kept it on with surge protector, but unplugged it when on vacation or during thunderstorms. You could call Mola Mola to be sure. | |
| Surge protector tatooedtrackmen, It is hard to tell what is sufficient since lightning can have different forms. Nothing will protect against direct hit and everything else depends on the distance and location. More protection is always better. I decided to ge... | |
| Surge protector tatooedtrackmen, I suspect that the amount of energy circuit can absorb depends on physical size of components used (MOVs) and it might be related to overall size. Breaker is rated 10kA max current while physically larger whole house protector fr... | |
| Surge protector Whole house protection is necessary, since almost everything these days contains electronics (even light bulbs). I replaced myself, in my Siemens style panel, double circuit breaker with whole house surge protected circuit breaker https://www.ho... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong Eric, very interesting. I had similar situation switching from Rowland 102, an early Icepower (200ASC) class D amp, to Benchmark AHB2 class A/B. Rowland was a little bit darkish sounding while Benchmark is vivid and airy with better treble exten... | |
| Apple iTunes or What Else I use Itunes with Airport Express on 5GHz with no dropouts (Mac Mini). What is being sent to Airport Express is compressed data in packets (not in the real time). Programs, or anything else, don’t make any difference (since it is just a "bit perfe... | |
| What should I use to convert FLAC files to AIFF? XLD - Free | |
| It is balanced or not? joser9616, you're welcome. OPA2134 has also high current drive ability making it a good choice for an output amp (combined function of I/V converter and output driver). | |
| It is balanced or not? AD1955 has differential current output (two current output pins). In order to make differential voltage output (balanced output) it needs two current to voltage converters. OPA2134, being very low bias current dual amp, is good candidate for that. |
