| Who is using passive preamps and why? Pubul57, the engineers among us can give sound scientific reasons why resistors should outperform transformers just as they can explain why transistors should outperform tubes. However, there is a large contingency out here who swear by these supp... | |
| Who is using passive preamps and why? I completely agree that some components demand that you use an active preamp and such systems are capable of superb performance, but I think perhaps you missed my main point. The main point of my post was that it is not the passive volume control ... | |
| Who is using passive preamps and why? Paul is correct. Those who dismiss them as wimpy and lacking dynamics and bass simply don't know what they are talking about. That may have been their experience with them but that isn't the fault of the passive, it is the fault of the people tryi... | |
| Who is using passive preamps and why? "seldom any discussion" ????????????This has been debated to death. Do a search on passive and you will find hundreds of threads about this topic. I can't imagine anything will come up in this thread that hasn't been stated many times before., | |
| Why are my mosfet fuses blowing? A short in the speaker should be audible at moderate levels; one or more of the drivers would not be working. It is also an unlikely scenario. Failures in speakers are typically something burning up because they were over driven. This results in a... | |
| Resistor values .For -4.8 dB (how did you figure that) you need to reduce the voltage across the speaker by about 40%. The value of resistor you put in series with the speaker will depend on the impedance of the tweeter. For an 8 ohm driver you need about a 5.3 o... | |
| current versus watts Amps aren't rated for "max current" since that depends on the load. Most amps are voltage amplifiers; they try to hold the output voltage at a certain level for a given input and the amount of current they produce depends on the load. The 300W/8oh... | |
| current versus watts Is high current as important to quality dynamic sound as high watts.You can't separate the two as current and power are proportional.current = square root of (power divided by ohms)300 watts into 8 ohms takes about 6.12 amps of current600 watts in... | |
| Why are my mosfet fuses blowing? You are blowing the fuses for the driver stageThe Classé CAM200 equipped with a rail currents sensors to protect the output drivers under extreme condition such as short output, and Mosfet fuses (2AG 1/2 PT, 1/2 amp fast blow) to protect the Mosf... | |
| Recommend tube meter You need a DC voltmeter, not a "tube meter.". Radio Shack has them. Ask them for a DVM or a multimeter. It will be able to measure AC voltage, DC voltage and resistance. Set it to DC volts and you are in business.. | |
| External hard drives and sound quality You ask a question that only you can answer. The only way you can tell is to try it and see if you hear a difference. These types of questions always get 2 types of responses which has already occurred.1. bits are bits, how could it possibly matte... | |
| Got any DAC suggestions for a Mac Mini server? You have many possibilities. I am currently using an RME Fireface 400 which can be had for around $1,000 or so used. This will connect to the mini via firewire and give you 8 channels of analog output as well as analog in if you want. I'm using mi... | |
| Gain Question You don't "need" to run the MM into the MM input. You could try it into the MC as long as the phono stage has enough headroom. It would not be ideal since the MC input wouldn't have the capactive loading that the MM wants to see so not a permanent... | |
| Gain Question Do you want it to be louder? If not you actually get the best sound with the volume control at or near maximum. If you don't want it to go louder you are in an ideal situation. Your phono pre has quite a bit of gain so I suspect a step up will ove... | |
| Albums with mixed formats of ALAC, mpeg, mp3, WAV iTunes will play all of those formats at any rate. It will not play FLAC but all of them can be converted to AIFF if you wish. A program called MAX will do it for you. There is a plug-in called Fluke that will let iTunes play FLAC but the last tim... |
