Just a bit of trivia, do you know that it is actually hard to tell a 6x gain and a 3x gain amp apart?  Due to the way our ear hear things, we only register a moderate increase in volume when we double the output power, I know that in principle, but I was just testing a 6x custom order unit out a while back, and before I put it on the scope, I had a listen.  I was kinda surprised about how little difference the volume control's setting between the 6x and 3x model.   I actually thought I might have set it up wrong, but on a scope, it shows up just fine, with twice as much gain as the 3x model.

This is why I don't offer every integer step of the gain setting between 1 and 11, because it would not really help anyone by having that much gain option when your ear would have a hard time telling apart a 3x amp from a 4x amp.

Anyways, have fun. ;)

Haven't seen you around Head-Fi for a while David. I hope you're doing well. :-) 

Do you plan to release any new products in the near future?

Thanks!  I used to "patrol" the forums, but as I get more and more involved in product development, I got less and less energy to surf the forums.  I kinda moved from customer relations to product development. :P

We are actually currently selling a new product in Taiwan, but due to the limited quantity and cosmetic flaw on the case, we decided to just selling this batch in Taiwan, and once this batch is done, we will have a replacement for it that is designed to be about a level or two above the current product.

What's the product? It's a mini-DAC with USB/Coax/Toslink input, RCA and a very powerful headphone out.  We are working on the new one at the moment, it will be made with aluminum case instead of the current chromed-ABS plastic.

One very interesting feature of our DAC's headphone amp will be that it does NOT use traditional volume pot for volume, it will be electronically controlled, which will make sure it is always balanced, sounds good and won't wear out very soon.  (those tiny/blocky volume pots in headphones can wear out really quickly, and it would be a drag to hear scratching noises every time you change the volume)

I'll let you guys know more once I got something to show. ;)

Hi David,

I am seriously considering your HA-006 standard dynalo without stepped attenuator.

I would use it primarily with a Grado 325i (32Ω) and was wondering what gain setting (1,3,11) do you recommend? 

Go with the 3x gain setting.  That is what David suggested to me with these Grado cans.

It's a great Gilmore amp for great Grado cans!

Yeap, that's the ticket, 3x gain.  Thanks!

Got my HA-006+ and man, this amp is sweet with my Grados.  I can finally enjoy what these headphones can offer.
