How young are you that you can hear 20khz? You must be under 18 or something. I feel old... Also what music has stuff in that frequency region, or are you doing a sweep?

A couple of questions that have come up recently...

1. What exactly are "Sophia tubes?"

Reading their website, it appears they don't make tubes but rather acquire NOS tubes and categorize them into quality ratings based on how they test? So if you buy one, how do you know if it's an RCA, Siemens, Silvania, or Mullard, etc.? Don't they all have different signatures?

2. Recent focus on the GS-X has me wondering...

The GS-X is a refinement of the GS-1 (primarily the power supply and XLR outputs) so I imagine that the audible improvements over the GS-1 would be rather small/subtle. A little google searching turned up the Sheer Audio HA-006, which is another dynalo amp that claims comparable performance to the GS-1. Is it fair to say that if all of these amps strictly follow Kevin Gilmores model, wouldnt the $450 HA-006 be a good choice for the HD800?

And also, where does the Gilmore Lite fit in? Used examples with separate power supply are regularly listed for about $300.

Sophia tubes. (Click on "Tubes" in left hand nav)

 

I've owned Sophia rectifiers and liked them, though I'm not sure the cost vs. good NOS tubes was justified.

Sophia does not "refurbish" NOS tubes. They are new production tubes. I heard they're just TJ Full music rebranded (internal looks the same).

 

Money is better spent on NOS tubes instead imo.

I believe the newer gs-x mk2 actually uses improved dynalo+ boards so there are more differences than just separate psu chassis and balanced input output. How much of a difference that makes though I'm not sure
post #5391 of 12398
GS-X is more or less two GS-1s side by side so you get a real balanced amp.
The GS-1 could/can be updated with the Dynalo+ module though.
I think the GS-1 is sufficient to drive the HD800 though but havent tried the GS-X so cant judge the difference.

My Dynalo, which according to some, was a great build-sounded pretty bad with the HD800. I would *hope* the GSX fleshes the sound out a bit more-and imagine it does going by impressions around here.

The Dynalos are supposed to be "wire with gain" type amps, right?

With an easy to drive headphone like the HD800, they should all sound more or less the same. I haven't heard any of them, but if the above is true, then I would expect what,any head-fiers describe as a "thin, dry, and bright" sound from the HD800 - much like the Objective2.

That's precisely what I experienced. ;)

 

I don't know about the 'wire with a gain' that gets thrown around so much. The most dead neutral amp I EVER heard was the Master 8-and even though I found it completely lifeless with the HD800-I didn't really find the treble too bothersome like most every other ss amp I tried the Senns on.

"....the power levels of the GS-1 are well suited for the mass of high-end headphones that includes the Sennheiser 600 thru 800, Grados, etc...as well as for use as a speaker pre-amp."

I'm not sure if that's true for their whole range but my Full Music 6SN7 look exactly the same as the Sophia Electric equivalent. As to which is the rebrand I couldn't say. I'm very happy with my Full Music valves.

Is this Bobby Moore on your avatar?

Just picked up the WA7 from the Post Office and setup it up.  Man is this thing small compared to the Schiit stack (ok, the power supply is huge but is sitting under my desk).

 

Although I ordered the stock Sovtek and upgraded Electro-Harmonix tubes, I'll let it break in with the Sovtek to get used to the sound signature. First song.. The Longest Road (Deadmou5 ReMix).. Wow, this thing kicks out the bass. Now to give it some time, let it and me break in with a variety of music and a Rust Nail (Scotch & Drambuie) or two or three...

Really? I loved the GS-1/HD800 combo. So much more than the ZD/HD800 that I heard (very uninspiring).
