Directstream Regulator question

For me it was the midrange. Vocals in particular.

That said, I think every aspect was better. I personally noticed mid had the most positive effect.

Aha,okay,i will be aware of that and observe the soundā€¦now itā€™s twoo daysā€¦more to comeā€¦Ted sad,that burn-in is high hundreds of hours,so,that may not be correct,as twoo weeks are 336 hoursā€¦Edcor also says,that these hours arenā€™t proper,it is less,than thatā€¦But,if you have this experience,i can believe youā€¦so,little waiting neededā€¦

:joy: that did make me laugh, thanks Elk

I felt the biggest effect (for me) was in the bass, but these days I canā€™t even remember what I had for dinner the night before (unless it was an expensive night out).

So,in whole matter,it is the midrange and bass,so,mostly the whole spectrum,which is better generallyā€¦how much did you burn-in DSD DAC,you have also upgraded transformers?

May i ask forum guys with upgraded DSD DACā€™s,on which volume level are you listening,if the DAC is feed directly to amplifier? I have level of 50 in my roomā€¦

When I ran my stock DS direct to my JC5 ampā€¦I varied the
DSā€™s volume control to adjust volume to suite my taste at that
particular momentā€¦

Going DS direct to amp it will be necessary to utilize the
DS volume control as you would in preampā€¦

As an asideā€¦while I really was impressed with DS direct to
ampā€¦there was much better sound quality, spacial retrieval
and body to the musicā€¦my premp is a Stage 2 Wyred4Sound
STP SEā€¦

My .02 thinking is that the same would hold true for a moded DSā€¦

Hope this helps
Best wishes

You did not say,at which level volume is set,when directly to the amplifierā€¦Is it 50,or 60?

You are rightā€¦because you will need to vary your DSā€™s
volume level to meet the your individual needsā€¦

Too soft ā€¦then raise volumeā€¦ too highā€¦then lower volumeā€¦
use your earsā€¦they will tell you what is best

Best wishes

When it is 60,you cannot listen?

Does your power amps have adjustable gain levels?
Or are they fixed?

I have Cello Duet 350 amplifierā€¦I donā€™t know,probably it is fixed,no regulation to be seen on itā€¦

Nice ampā€¦it seems then that amps inputs are fixedā€¦

Your sound level comfort will tell you the proper
DS volume levelā€¦simply adjust to your tasteā€¦

Let your ears be your guideā€¦

There is no right or wrong level when using the DS as
preamplifier direct to ampā€¦

Donā€™t get hung up on a numbers gameā€¦

Running my DS to preamp I set the DS to 97 and vary my
preā€™s volume to suit my desired listening level.
If you ran your DS at 97 direct to ampā€¦you would either blow your speakers or your ears or bothā€¦

I would start low on the DS direct to amp and raise the DS
volume control until you achieve your desire listening level.

Best wishes

Thank youā€¦

Thereā€™s a LOT of variability on that since the gain on every amplifier is a little different - 50 on an amp with low gain will be too soft, but on a high gain amp will blow the listenerā€™s ears off. Some even have to initiate the attenuator.

The DS does have lower than ā€œnormalā€ max output voltages though - 2.818v on balanced and 1.414v on unbalanced, so even maxed out, the final output (if not using a preamp) will be lower than a source that has the ā€œtypicalā€ output of 4v balanced / 2v unbalanced. Even with a preamp, you would likely find the need to set the volume higher than you would otherwise with other source equipment.

Edit: I should mention that I donā€™t believe the better Edcor changes anything as far as output voltage, as they are both 1:1 transformers (I think).

I cannot set volume louder,than 60ā€¦how much you do set it for,if on amplifier directly?

I have personally never tried DS direct to amp, as when I got the DS, I already had a preamp, and have PERSONALLY found in the past that a preamp consistently improves the overall sound. I used to use a Wyred STP-SE, but recently got my hands on a BHK.

If you prefer to use the DS direct, but would prefer to set the output higher, have you tried initiating the attenuator?

Thereā€™s a quite long thread in the DAC forum with a lengthy discussion about volume settings between members, with some saying they canā€™t even go over 40 or 50 when using the DS direct, and I recall some even complaining that they canā€™t get it loud enough going direct (ie. where the low DS output voltage, variability in amp gain, speaker efficiency, etc. come in to play).

I wouldnā€™t get stuck on any specific volume setting at all, since the volume in the DS is technically lossless because of how it works. Whatever setting works within the parameters of your system (amp gain/speaker efficiency/room interaction) is what works in your instance.

On the other end though, there seems to be consensus, including Tedā€™s input, that the DS sounds best at about 93-95 MAX (not min) because of the software/firmware for the FPGA, signal/noise, etc. when using with a preamp.

If you search ā€œvolumeā€ in the DAC category, youā€™ll find quite a few discussions about it. I donā€™t recall which thread specifically addressed the 93-95 max thing, but I recall it coming up in more than a few threads.

Great answer tak1313ā€¦

Wonder how my Stage 2 would compare with BHK preā€¦

Needed to say my Stage 2 is amazing !!

It is better with preamplifier thenā€¦50 is enough volume for directly to amplifierā€¦more you cannot set,only,if cd is recorded silentlyā€¦

Before I got the deal on the BHK, I was debating about the upgrade (Stage 2, since the Stage 1 seemed kind of useless in light of the Stage 2 and the cost difference). I really donā€™t know how the stock versus upgraded would be.

Iā€™m debating about getting the upgrade anyway, then comparing it to the BHK. Have you heard it stock before upgrade, or did you buy it with the upgrades installed (since Wyred sells them both ways). If you did get it stock first, whatā€™s the difference?

Where do you live? If you live around New England, you can try my BHK in your system to see (I live in NH). It currently has Gold Lions.
