You can do it without active crossovers. The headroom benefit won't be as significant since the amps will be outputting the full voltage waveforms but the current draws will be less so there will be some additional headroom as the cahnce of power supply sag will be reduced. I'd try the...
OK, no response to my post in the other thread so here it is again! In the past, I have been happy to use a mid level receiver as an AV prepro since the dedicated units cost ridiculous (to me) amounts of money. Now that NAD have the T163 prepro at RRP of A$1499, I'm tempted to look at this as...
Matt, did you try using the MCA power amps with the Pioneer Elite receiver as a prepro? I'd be interested in how it sounds vs the Anthem AVM In the past, I have been happy to use a mid level receiver as an AV prepro since the dedicated units cost ridiculous (to me) amounts of money. Now that...
The way power specs are measured (one channel?, one channel others 1/8th loaded?....), it's like qualifying the above claim by adding "0 - 60 time of 4 seconds if you push it off a cliff". Greg
It does sound like amp protection circuits are cutting in but could be that this protection occurs when the preamp circuit senses it will clip the internal amps in the receiver - my Sony receiver goes into protection mode if the volume is cranked too high even though I'm using it purely as a...
They stick resistors across the output (usually 8 ohm, sometimes quoted for other resisitance) and then measure the RMS voltage across them at the THD they want to quote (using sine waves). Then P = V * V / R.
For HT, once you have decent surround sound, it's better to allocate resources towards upgrading the picture. To me, decent is ~US$800 receiver + ~US$500 sub + ~US$700 fronts (inc center) + ~US$300 rears. You already have a great stereo system so don't waste your money trying to raise the...
Shh. Don't tell the Lexicon/Meridian fans ;). I fully agree. A decent US$800 receiver makes a fine prepro (or semi prepro - ie powering center and surrounds) for those integrating HT into a good stereo setup. Hey John_KM, you're also an Aussie, right?
Ed St. Clair:
OK, let me put it another way. Most high end amps have a lot of capacitance in the power supply. This is to soak up noise from the power lines and also to supply power for large signal transients so the transformer inductance doesn't choke the output during heavy demand...
Well there has been some fairly heated discussion of these topics in the Sources forum (along with debates about Redbook vs the hi-res audio formats vs LP) but not much of late. Most of the people involved with those threads are also here (aside from John Kotches and Lee Scoggins). Not...
Brian Fitterman:
It's to do with the rise time of the transitions. A cable that loads the SPDIF output could cause the transition to have such a large rise time that the transitions are clocked unevenly. Since the clock for PCM is recovered from these transitions, the result is jitter in the...
The only issue is that the clock itself is usually recovered from the edge timings of the manchester encoded SPDIF signal. This can result in jitter. Buffering and reclocking, of course, can remove this. I'm generally a cable skeptic but I think jitter can produce audible effects for digital...
Hi John, I don't mean all people but a lot with US$1000 CD players seem to form this opinion. And do you write off redbook as a medium? I don't think so.
I wonder how many people who like to write off redbook have heard it on a REALLY good CD player or DAC (like the Chord DAC64). As RobertR mentioned, it is the implementation of the digital filters (+ jitter minimization) that will make or break D->A conversion (assuming competent analog stages)...
