Having spent a great deal of time listening to gear and music with Iron_Dreamer, he has diversified his music choices, as have I. I never thought I'd find myself listening to Progressive Metal. LOL.

But if you look at his first post, he extensively lists the different songs he listened to. And it's not all Metal and Rock.

Yes, yes - This is not what I mean. I'll try to explain with my limited english. I suppose he prefers certain music styles over others, as we all do. And is normal we listen for different "things" in different styles of music. You can listen to a wide variety of music, but prefer certain "presentation" because you are more partial to one style whose strong point is this "presentation". Hard rock/metal and classical sound certainly are very different. Only asking if this could be the case.

By the way, I'm a heavy metal lover too since the beginnings of the '80s

I didn't want to question his comment about the sound quality in comparison to the Benchmark.

doesn't make much sense since the guy that designed the DAC claims the DAC doesn't provide jitter reduction in bypass mode.

How exactly would it not provide some jitter reduction. You'd be hard pressed to build a S/PDIF device that does not provide some jitter reduction from the standard chips available on the market.

A digital receiver chip like the CS8416 does of course use a PLL to extract a low jitter version of the clock embedded in the S/PDIF stream.

There might no secondary PLL like the crystal lock circuit in the Lavry or an ASRC but the primary PLL in the receiver chip is always there.

An interesting question is how you would ever compare the quality of a S/PDIF signal without this. I suppose older generations of the receiver chips did pass most of the jitter through to its clock output.

Cheers

Thomas

So, if I might paraphrase, you are essentially saying that my preference for rock/metal effects how I like to have classical/orchestral music sound? If this is the case, well then I am not entirely sure it is true. For instance, I am not generally listening for soundstaging intracacies or how natural or convincing an acoustic instrument sounds when listening to metal. There are certainly some characteristics that I want to hear regarless of the type of music I'm listening to , like instrument seperation and definition, impact/dynamics, and high and low end extension. I would generally say that there are specific qualities I look for in different types of music, because those genres make those qualities easier to discern (i.e. soundstaging in classical, or bass impact in metal). Overall, I listen to music to be excited and have a good time, regardless of the genre, so most of the time I don't favor soft/quiet music that lacks dynamics.

Considering that the two folks so far that prefer using the upsampling capability of the Aqvox both do so with the K1000, perhaps there is a certain synergy there?

They said that they were sent back to Lavry for an update and returned to Pure Sound. Hopefully that was fixed.

As far as I know this was done to reprogram a couple of chips which caused the wrong volume number to show for a few setting, and fix how it handled a certain sample rate. If this is the case, then it is from the first back, and has the improperly labelled outputs which are supposed to be fixed on the next batch of units to come out.

I "fixed" the lock LED on mine by just bending the plastic part that holds the LED to better fit the hole. Hopefully this is something they'll do a better job of on the next bach as well.
