Audio-gd Master-5/6/8/9 balanced head amp/ preamp - Page 23

post #331 of 866

Well could be the XLR cable I built was crap (it's probably too inductive as I used the VHAudio interconnect recipe - new cable is same wire but just loose strands) or of course level differences or placebo (although I did my best to match level by ear), CustomNuts also told me he thinks the two connection methods sound too similar to tell apart.  The downside with ACCS is the mini-XLR connectors are a bit fiddly to wire, and at least the Rean connectors I was using don't seem to be built to very fine tolerances (Switchcrafts were 4 times more expensive though so I took my chances.)  Either way I like what I heartongue_smile.gif

 

Here's a picture of anyway:

On another point I made up a ACSS cable using Homegrown Audio solid silver cable and there is very little if any difference between it and my Artisan Ultimate Silver XLR cable. Both are pure silver,one solid one stranded, but I could not tell the difference in a blind test. Total cost of the Artisan was about £200 and the HomegrownAudio about £55. Both are excellent!

I made up some ACSS cables using silver solid core wire from Handmade electronics. Big difference in clarity over stock.

I never had the stock ACSS cables so can't do any comparisons.

The Master-6 sounds so good via XLR that I almost did not bother with ACSS but I decided I wanted to free up the XLR's on my NFB-7 for when/if I purchase another balanced amp.

Just reterminate the cable it came with- super easy if you have a solder gun, solder and a the plugs needed (can be bought from AGD when ordering the Master-8). I promise you can do it. PM me if you need further help on this.

 

Thank you sir!  biggrin.gif

 

I know it's a ridiculous question for this kind of amp, has anyone tried with IEM?  any hiss?  or even causing the driver to explode?

If you have tried, what IEM was that?

I tried it with my Klipsch X10 and it works but you'll find that volume can't get much beyond 5/99 (1-2/99 for me) depending on source and sensitivity of the IEM.

Do you hear hiss when no music is playing?

Tried with my SM3 (122dB, 34 Ohms) and no hiss even when no music playing. However there was hum (from a transformer somewhere).

Quiet mechanical hum from transformer?

 

Had similar issue with my RE-1. Turned out my AC power line had some DC in it. Solved with DC blocking filter. Complete system is dead silent since (when paused wink.gif ).

Thanks for testing for me.

 

 

Guys, do you (heavy) stack Audio-gd on top of each other?  like Master8 on top of Ref. 7.1?  (with some non-conductive layer of course)

post #340 of 866

If you must it's probably a good idea to separate the chassis a decent amount to allow adequate ventilation.  I just used 3 offcuts of pine and doesn't seem to get too hot.  I might use some wood spikes on the ref 7.1 to get some airflow underneath someday as well...  Advantage of stacking IMO is you can use very very short interconnects (but then again Master 6 and REf 7.1 use plenty of hookup wiring so who's kidding who with interconnects)

Ok, heat related concern noted.

 

I'm worried that the metal feet would make a permanent mark to the other gear, don't you think?

post #342 of 866

There possibly a chance of that also, I guess you could use rubber/felt pads or some other isolation device.  My 3 offcuts of wood work a charm lolbiggrin.gif

post #343 of 866

Just got my Master 8 in yesterday.  This thing is built like a tank.  I didn't expect it to be quite so deep so I had to do some reshuffling which took up most of my night.  I'm very pleased with it.  Using the stock XLR provided with the LCD-3 and it sounds sublime.  Looking forward to being able to mess around with it more tonight.

^Thanks. Do you have other amp to compare the sound to?

Never hiss anywhere- all his gear is dead silent
