| Rectifier Tubes At the top of rectified full wave sinewave current changes direction but rectifier is too slow to respond and keeps conducting in opposite direction for a moment then snaps back to zero current. Fast snapping back creates very narrow negative curr... | |
| Yter cables direction Why would you think it is important if manufacturer doesn't (doesn't mark it)? I could not find anything about directionality on their website. | |
| Help with choosing music server You rip a CD and it pretty much gets organized the same way iTunes does.I don't like amount of scrolling you have to do to get to particular album in Itunes, but if you create "smart playlists" for each genre (like "genre IS Jazz") then Itunes dis... | |
| Could I be a Retail Wretch? Happy to pay for test drive? Nobody would even accept money for that. It is assumed a cost of doing business and I wonder why Audio has to be different? (some dealers already charge for audition). | |
| Difference between " AES " and " RMS " power of a driver. It is not mutually exclusive. I appreciate technically correct terms AND I know what advertising, hi-fi magazines, audio reviews etc. mean. | |
| Could I be a Retail Wretch? Viridian, It is hard to tell dealer that I will buy or not buy the car if I never drove it. Test drive and presentation is treated as a service on behalf of the car maker. I just bought a car few months ago - 2019 brand new design. This car will n... | |
| Could I be a Retail Wretch? Would yo be HAPPY to pay for test drive of the car? | |
| Could I be a Retail Wretch? Class dealer? Audio dealers recently charge for audition!!! I don't see a reason why anybody wouldn't give dealer a chance to match the price. Saying so is a strawman argument. | |
| Which DAC: Benchmark, Mytek, Audio Mirror, Holo Audio, Mojo Audio? D50, even without power supply is very cheap. I expected bad quality to follow, but pictures of the PC board show good quality with most of SMT components (very repeatable process) similar to Benchmark. There might be some non-SMT capacitors, bu... | |
| Difference between " AES " and " RMS " power of a driver. RMS power is erroneous term. RMS voltage multiplied by RMS current gives AVERAGE (and not RMS) power. For sinewave average power is equal half of peak power (there is such thing as RMS power but has different value and does not represent anythin... | |
| Which DAC: Benchmark, Mytek, Audio Mirror, Holo Audio, Mojo Audio? Musichead, there is no "better" in my opinion, since it is very subjective. I had Benchmark DAC1 before and it was extremely clean, but a still little "lean" sounding (in spite of my opamp modification). My new Benchmark DAC3 HGC, in comparison,... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Ramtubes, AHB2 has load/line regulated SMPS, but as you mentioned, there are losses everywhere. Exact doubling of power for half of the load means perfect regulation - an ideal voltage source, that is only possible with very deep negative feedbac... | |
| No one actually knows how to lculate what speaker cable they need as a copper wire alone shall have no inductive or capacitance at all!Of course straight wire has inductance. It is on average in order of 0.4uH/ft that represents about 0.2ohm at 10kHz for 8' wire. | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Power specified at 6ohm is 130W. Theoretical ideal power bridged at 6ohm should be 520W and is 480W (7.7% less). Also current was changed to 29A per channel. Perhaps 18A specification was for the early versions. | |
| Clean Power without the drawbacks of Conditioning Filtering. Advice? Dumbeat, I use Firman Elite 20PFI. Built in Power Factor Correction consists of big inductor and capacitor. They stores energy and are able to deliver up to 58A of peak current.Most of linear power supplies take current from mains in very narrow... |
