post #466 of 771

a Quicky clarification

Quicky,

I'm confused when you use the term NOS. The conventional meaning is New Old Stock. It usually does not refer to characteristic sonic attributes. The only possible exception to this I know of is when NOS is used to refer to NOS tubes compared to new manufacture tubes, but even then, the variety of sound from NOS tubes is... well, various.

Could you clarify for me as I am interested in your review.

NOS DAC = Non Over Sampling DAC
post #468 of 771
Non-over-sampling.

I just ordered the DAC Straight from Dave and must say that his patience in helping select the proper unit for my setup was phenomenal.

His customer service is world class and he's a really nice guy from a great city...Winnipeg (my wife's home town).

Thanks Dave. I can't wait to try this unit!

NOS = Non-Over-Sampling, got it!

I've got a HotUSB 1 dac that sounds great. I understand that a DAC Straight might be more detailed. Often more detail results in too much brightness and a loss of natural timbre. Can anyone tell me how the DAC Straight sounds vs the HotUSB 1?

I'm actually working on that now.

Or rather, would be, but thanks to allergies my hearing is messed up at the moment. For a few days (while on my "vacation"), everything sounded like it was underwater. Now there's just that water in the ear feeling in my right ear...which doesn't seem to be affecting my listening, but I don't feel like I should make critical notes when I know my ear is not right.

My other problem is that I'd be comparing the Dac Straight + a BJC vs. the USB1 + radioshack mini to RAC cable. Oh, and my Dac Straight probably only has 35 hours on it vs. the 300 (at least?) of the USB1. That's not exactly apples to apples.

From memory, I can say that I prefer the Dac Straight setup. I don't feel it's brighter, just more detailed, specifically on the low end out of my EF1. I have to think that with more burn in, it would be even better.

Hopefully this'll go away in a day or two and I can make some official notes.

I've been shopping around for a DAC and most are either out of my budget or they're a lesser known brand from China/HK, the latter being something i'd like to avoid for now. I was thinking of getting a high end soundcard instead since they're cheaper in AUS and easier to find, but i dunno, damn this HiFi stuff is really confusing lol.

sdcloud69,

Avoid the soundcard if you want good sound. Now way around that.

Can't answer re the Little Dot I+. If you don't get an answer here, go to the Hotaudio site and contact the manufacturer. He is very helpful.

I think it is a good match for any amp, receiver, etc.
But I don't have an Little Dot I+ to try it out...

But I see no reason it wouldn't work great...

Thanks, Wenglish,

Looking forward to your impressions, though it seems like the DAC Straight would fit my bill if it is not bright at only 30 hours.

Dave I see you trimmed your DAC offerings recently. Are all the remaining models the same as they were previously, or have some gone under the knife for upgrades? (I notice the Mark VII now has a different volume knob.)
post #477 of 771
They are all being upgraded at all times...

If I find a better solution, then I use it across the whole DAC / AMP line...

I trimmed the offerings to make it a little less confusing, as some people were having trouble sorting out all my units....

The knob on the MARK VII is just for a different look...

You will be seeing lots of new looks as I have hundreds of knobs in stock....

You will still be able to find all my items on my personal website, but my evilbay store inventory has been trimmed substantially...

just received my mark IV.Initial impressions are good however there is significant hiss from DAC even when all sounds are mute from computer.

Since I listen at fairly low volume levels, the hiss is quite distracting during the quieter parts of the music. I did read about some of the previous comments about the hiss, but they for about PCM6102 based amp and unlike that amp this does not have a volume control.

would the hiss decrease with burn in?
any other tips to decrease the hiss ?

Oh geez, the price of DAC DESTROYER is getting lower and lower. When i got it about a week ago, it was 63 euros, now it's 51. Still, the DAC is awesome, and i'm enjoying it alot.

what can
I think the hiss is a function of two things...

The sensitivity of the headphones,
and the impedance of the headphones.

I believe that most likely the MARK IV is just too powerful for those headphones, because with other headphones there is no audible hiss whatsoever.

Probably the MARK IV should ONLY be used with hard to drive headphones.
Same goes with the SUPREME as these are quite powerful DAC / AMPs.

A more compatible DAC for sensitive headphones would be the DAC DESTROYER as it has no buffer stage and has about 1/6 the output power...

Your phones are just too sensitive for that much power.
They're picking up everything as some / most IEMs do....

EDIT: After doing some more looking at my database of issues...
I noticed that ALL the headphones that were experiencing "hiss" issues had impedance's UNDER 32 Ohms....

Interesting...

I've now put a note on all my products that they are ONLY compatible with 32 to 300 Ohm headphones.
Within that range there doesn't seem to be too many issues, except for the harder to drive 300 ohm headphones...
And for those, I usually recommend the use of an additional headphone amplifier for the extra voltage required by them ( 300 ohms ).
