Now you've got me concerned.

Dub step the dac you have is very detailed . I have that dac . Buy new and buy the M9 from audio gd it has great sonics to it. I have the m7/m8 combo and it's great and has more than enough owner for the he 6 and is pure class A amps ...

I own several amps to use with the he6 include ding the woo wa5 all in. And to me the audio gd combo is better . You should be able to find a M8 used to and it will be faily new. And it is a great pre amp to. Only draw back is it is a heater as class a amps are. It's all discrete as well. Good luck

If your HE-6 are 50 ohms or so, you will be able to deliver nearly 3.4 Watts into the HE-6.  What does that mean for headroom?  I'm not sure.  Depends on how loud you listen.  It may be just fine.

 

The Headamp GS-X spec says 15 V peak to peak single ended, 30 V peak to peak balanced.  That +/- 7 V single ended, +/-15 V balanced.  For 50 ohm load that would equate to 1 Watts peak single ended, 4.5 Watts balanced.  Although, they spec 1 watt single ended, 2 watts balanced, so there may be a current limit dropping that balanced spec, OR the power specs are RMS, not peak ratings, I can't tell.

 

In any case, you would have slightly less headroom with the F3 than with the Headamp in balanced configuration.

 

Hope that helps a bit.

FYI...those are the MK1 with the old Dynalo modules, not the GS-X MK2. Justin should really get around to updating them. :smile:

does it come with that pre-amp in the pic? 

No, the preamp is not included. I think the preamp is in another ad for sale. If you have a DAC with variable volume control you can connect it directly or if any of your headphone amps has pre outs you probably can use it too.

 

After being serviced it should last for many many years. I have a Threshold T550e that I bought in 1997 new, it never has been serviced and runs beautifully. Basically when they are serviced the main thing is to replace the capacitors and after those being change they can last at least 20 years or more.

  There seems to be a tendency here to focus on amps and discount the importance of a preamp. my experience is that some combinations are much better than others.  Some amps sound ordinary with the wrong pre.  One pretty good amp i have sounds great with a pre from the same maker, but pretty average with another pre i have (and like a good deal).  Of course auditioning is best, but if one has to rely on reviews, it makes sense to focus on the whole set up and not just the amp.  One reason to think about an integrated is there is one fewer variable in the equation, although your options for changing things up are more limited as well.

^^ Very good point ^^

post #10313 of 14031
I will say this and this is not meant to be a dig. The less devices in front of your ears the better . So an amp with the pre built in is good but a dac with the pre built in is better , and last is a separate pre all together. I own some hi end pre,s and although some add a quality you may like like tube sound , in the end for absolute sound less is more..

Not so sure about that.  Most integrated amps use an analog pre amp.  Most DACs use Digital pre amps (not all, but most).  In this case the pre amps in DACs are"sometimes" inferior to analog pre amps.  The best analog pre "should" have an advantage over the best digital pre.  

 

Brunk will chime in on this - he has been looking into pres a lot lately.  

 

I know the NAD M51 has a really good digital pre amp.  The PWD2 not so much compared to the NAD.  The AMR (dac) use an analog pre amp.

: :   200   : :  I am sooo close! I pushed another 8 hrs onto the cans overnight, bringing my total to 190 hrs. The cans/cable have been a bit sleepy to date but I feel they have awakened in the last 12 hrs.

 

Things are looking up! 

post #10316 of 14031
As I understand what you say and do agree with the point. I still feel less is more and most all dacs have a analog stage output even if set voltage. So my point was adding in a pre when not needed is over all detrimental to the sound . This is not something I thought of but have read the statement in some forums and I just agree with it. Even Steve of imperial made this statement . Just a thought for someone looking for adding a preamp as this would help there system.

Bold 1) I agree preamps are probably the most overlooked component across all horizons of music delivery, whether it be headphones or 2 channel.

Bold 2) An integrated is nice, but what if you don't like the overall sound of the pre want to experience different? It only eliminates a variable in that you're assuming/hoping it's the best it can be. Unfortunately that's rarely the case.

I agree less is always more, but only when very carefully designed and selected for your particular system and desired outcome. Most DACs do not have an analog pre, they will use the digital pre.
Today's digital pres (32-bit domain) do exceed the quality of a standard analog pot, like a basic blue velvet or something. 16-bit DACs back in the day did a horrible job, which is why there was such a distaste for digital pre. Here's why: Just to make it easy as possible i will be simple. Let's say you want your signal to be -40dB. In a 16-bit domain that -40dB will be represented as 1234567890, but it doesn't have the resolution down that low in attenuation, it can only represent 12345, the basic-design pot can represent 1234567 down that low. The 32-bit domain, it can represent it as 123456789012345, twice as much! It now beats the standard analog pot. However, a carefully designed pot/pre can represent 123456789012345678901234...., wayyyy more than digital can ever accomplish. That is why the dest digital pre will never beat out the best analog pre.

Apologies for the crappy formatting, but i hoped this help shed light on the topic, I can find some illustrations that demonstrate this if you guys wish. My opinion of pot/pre quality:
lowest to highest
1) 16-bit digital
2) standard grade pot/pre
3) 32-bit digital
4) high-grade pot/pre
 
Things to consider
1) A passive pre will always sound better in a passive-compliant system
2) An active pre will always sound better in a system that is not passive compliant
3) There's no reason a Head-Fi rig should be active-based, unless doing studio work, or have extremely long runs of cabling, exceeding 3 meters. But of course some of you have found great amps that require an active pre :)

I had been auditioning a Golden Tube SE-40 tube amp with their active pre and the pre sounded terrible. I ended up using the computer volume as the pre took away the dynamics of the amp. I have no problem using the digital volume of the Hilo and Darryl's pre is spotless with his F1J. It seems to be a hit or miss option with pre's as some are color free and have no impact on the signal and others just kill the dynamics. Perhaps that negative influence is caused by passive preamps but I've used passive volume controls with no noticeable sonic impact. I understand the argument that anything passive is bad but I think that's dependent on the quality of the components.

Also on 16 bit files you may never hear the short falls of a digital pre in a DAC.  When you start using 24 bit files and higher that's when the difference will be more noticeable.
