In fact, rather than follow the sensible advice to order an assortment of values that can be ganged, having more patience than a desire to end up with a pile of unused resistors, I've only ordered two 50-Ohm 10W 1% Vishay Dale wirewound resistors to start with:

For my quest, if this kills the hiss from my MG3 to LCD-2, I'll go to a lower value to see if I can still avoid hiss with yet a higher voltage output.  If not, I'll got to a higher value. One step at a time.  Slow but sure.

I dunno, I think you need to have a pile of unused resistors.  Unused resistors are fun.  For instance, you could solder unused resistors into a sculpture of some sort, perhaps calling it "pile of hotdogs"or "pack of wild dachshunds".  You could then sell your artwork for big bucks to finance your next portable gear upgrade.

 

I also think doing this testing one step at a time, slow but sure, is just not good enough.  You need to try to test everything at once, using a lab full of calibrated test equipment, and about 20 assistants in lab coats with "ZilchLabs" and their names stitched over the pockets, all of them setting up and monitoring the equipment, testing it constantly to ensure perfect level matching, with you in a remote location to ensure that you can't tell when they are switching ANYTHING in the system.  That way you would have a completely blind setup.  If you don't do all of this, your results will not be valid to anyone but yourself.  And you shouldn't be so selfish about just trying to upgrade your own gear, when the Nobel Prize committee is waiting for you to complete the grand experiment that will save all of humanity.

 

Okay, that's enough ranting, now back to preparing for my comparison of every single DAC on the planet, because everybody on Head-Fi seems to have different ideas about what should be in the field.  But that's a discussion for another thread.

 

By the way, here's my highly trained lab team:

You guys have it all wrong.  There will be one company, but many brands.  Consumers must have choices you know.

Yes like banks , as I open accounts two years later someone buys them and in that time new bank names pop up.

Curious, how many of you using speaker amps have thought about adding a woo wee and one of the stax headphones?  

post #1610 of 2933
I did think about it, but I own two ES amps , so how many do I need to try and they have to be better than the wee.

I own the wa Wes

Pretty sharp looking bunch of assistants, Gary!  I think a couple of them are slacking off, though....

ME!!!  Either that or one of the old Stax transformer/energizers if I can get Spritzer to upgrade one for me.  But he's pretty busy building all sorts of other stuff, so he hasn't been interested.  Looks like (one of?) next year's purchase(s) for me will be SR-007s and a Woo Wee.

All joking aside I was going to by one but I never read a review . And then was wondering how it would sound compared to a real amp ? Has anyone hear used one??

Yeah, but for what I pay them, I don't really expect much...

It depends on who you believe, plus what your expectations are, I guess.  There was one blind comparison test in France that favored it over several dedicated (and much more expensive) amps, both Stax and 3rd party.  Others say it scales well with better amps. However, Spritzer thinks it's a piece of junk, and he is pretty high up in the Stax Mafia, so you ignore his opinions at some peril :normal_smile :.   So it really comes down to whether you want to try it for $500, hoping it will work with your amp(s) and that it won't blow up, or want to save your pennies (LOTS of them) and buy a real Stax amp.  I think I'm gonna try it (I'll also buy a nice fire extinguisher... and still be several thousand bucks ahead compared to a KG or Headamp unit...).

I know jack of woo audio , I could ask him to listen to one I guess. He did tell me to try it before I bought any amps. I be leave it uses transformers to increase the voltage and a bios circuit.

Jack also told me once to stay away from ES amps with transformers that they hold back sound quality. So I do not know , but I do see them used to buy , so I would do that first .

I own a couple of ES headphones and the level of detail is above all the rest too. But other types have great qualities too.
When I bought my first set I purchased with the amp so I never did the comparison .

Just wondering, would something like this make an improvement to the TBI? http://www.aloaudio.com/the-passport

"I read somewhere" that THX standardized pre-amp and power amp gains, and the industry has (rightly or wrongly) tended to follow these "standards".

 

Personally, I find that my pre-amp and power amps (for speakers) have too much cumulative gain.
