What are your reasons to choose passive over active crossovers?

Maybe it's just a mental thing.

Reading some of the responses re: multiple conversions really leaves me wondering what some think is happening during the conversion ... like the signal is being dragged through a digital grinder of sorts, like sausage it's pressed back into the analog casing. Then it must be simmered on the best Class A cooktop to be really tasty.

LOL
 
I would like to find a way to put a mute button on my roommates dog who likes to bark and bark and bark until someone gets up shows him some attention at 3:00/4:00 AM because he wants to play and everyone is sleeping and he won't stop until he gets his way. In this case I don't care what it is. Space based laser systems would be just fine with me as long as I don't have to listen to his spoiled dog bark while he sleeps through it. :snoopy::nownow:
 
Us analog source guys (specifically vinyl) don't want to risk screwing up our carefully derived audio with two digital conversion processes, plus extra DSP. .


Yeah right. cos no records have ever gone through a digitial delay line in mastering. Once you let go of the irrational fear of an ADC in the signal path life becomes a lot easier as you only have digital to process.
 
RIAA filter in digital domain is still considered to be inferior to analog RIAA filter?, or extra AD/DA conversion is considered to be the bottleneck of digital RIAA processing? If we just look at the measurement, I think digital RIAA processing would be superior to most analog RIAA processing even if ADDA involved.

Which measurement? A digital riaa still requires an analog front end and you need to boost the signal sufficiently without being selective with respect to frequency. Not great for hf headroom and same issues with noise and distortion. So maybe the correction is smoother. Big deal.

Not by me.

A lot less front end gain required. Headroom is not an issue, noise is lower. What's not to like? (and sorry for being dragged off topic by vinyl)
 
FR and THD. I'm pretty sure that digital RIAA has an advantage regarding the accuracy of FR, but I'm not sure about THD as you said, since I have not seen any numbers comparing them. Have you?

FR and easy switch between EQ curves are the only advantages. The critical part of the amplification is preceding the ADC and there is no reason it will perform better than a standard riaa, on the contrary.

How many volts do you need at the ADC input? 3v? 3v/5mV @1kHz means a gain of 6000 for the linear pre. No way to optimize both distortion and S/N, even with a supply voltage of +/-45v.

I know that digital phono stages exist, but cannot see any purpose besides archiving.
 
a little bit of history
1) spinning disc, a needle on the groove which is attached to a membrane that is in the throat of a horn
2) spinning disc, a needle on the groove and the movement is converted to electrical signal, then amplified and sent to the transducer
3) spinning disc, a needle on the groove -now stereo!- and the movement is converted to electrical signal, then amplified and sent to the transducers

....4) 1981- We have now something better than vinyl...it's a CD!

...5) the modern times
 
FR accuracy is definitely an advantage of digital. Analog filter can't be accurate as digital even if not considering the compensation for different cartridges. Regular professional mic pres usually have 75dB gain, and no problem dealing with phono level signal, I guess. Is it not enough?
