Which amp is better? The GS-1, the Concerto or the Auditor? - Page 2

If I were you I would build (or get someone to build) a Sigma22 for the Gilmore Lite. This should put it up to or beyond GS-1 level.

When I posed the original question I knew the answer wouldn't be cut and dry. I knew there's a good dose of subjectivity to each amp. I didn't expect such conflicting responses though. From well established members also. None of which gets me closer to an answer.

It has made for interesting reading. If Dr Gilmore himself were to chime in, I might want to hear what he'd have to say. :)

Dynahi made a big improvement with Grados. I actually compared Glite and Dynahi few years back...lol..and Dynahi was substantially better, IIRC. (pardon my short auditory memory)

 

B22 bests Dynahi in pretty much all areas except heat produced, I think.  (it's been too long since I last had Dynahi) :D
 

I have only heard 3 amps that made me forget I was listening to a dynamic headphone (you know similar feeling when you hear a good STAX/HE60/90 - like you are hearing close-field spkrs):

 

Dynahi

B22

RSA B52

 

That's it. Many come close, but those are the 3.

I guess I should lug my dynahi to the northern NJ meet and let the OP decide for himself.

I hope I can make it. I would like to hear your dynahi and the other amps and headphones that will be there.

I'd make a priority list so I wouldn't get too ear fatigued and not be able to give all the equipment their proper due.

Thanks :)

That sounds like it might make sense.

Definitely cheaper than shelling out all the money for a GS-1

The Lite still has a worse pot than even the cheaper version of the GS1 though, doesn't that matter as well?

Yea there are some minor differences in the amp circuit. The GS-1 has separate L/R modules whereas they're on the same board in the Lite. The pot certainly makes a difference as well. The Sigma-22 would get it pretty close to the GS-1 though I suspect.

How would the Sigma-22 improve upon the DPS I have with my GLite?

I can't tell you specifics because I haven't tried the Sigma-22/Glite combination, but I can say with certainty that Dynalos benefit significantly from better PSUs and the Sigma-22 is far superior to the DPS despite its lower cost (benefits of a DIY design).

Unfortunately for me I don't have the skill for DIY. I'd need to find an assembled Sigma-22 and the cost benefit would be much less.

Contact MisterX or another reputable builder. It should be cheaper than the DPS.

The blessing, (and curse if hooked up wrong or shorted,) for the Sigma22 is that it has no current limiting to the design. Of the very few power supplies that I have looked at on the scope, the Sigma22 has bested them all with it's unwillingness to yield to a switching load.

I have never powered my Dynamite with anything but dual Sigmas, so hard to say what the audible differences would be between it and another.

 

I think one of the beneficial differences wrt the Dynahi/Beta22 as compared to others, ignoring design topology, is the use of higher rail voltage. With a twist, I would include the M3 to this catagory.

@baka1969

 

I run a similar setup to yours. Listening to it right now.

 

Foobar ALAC->M2Tech Hiface->Dacmagic ->SPL Auditor->HD800 (Cardas, Single ended)

 

While I haven't compared them to the other amps you mention, the Auditor is a great pairing in this setup. Very good soundstaging and imaging (nice sense of airiness). Instruments sound like they should. While I feel that the sense of 'blackness' could be better, this might be a source limitation.

 

Sadly, my B22 is in need of repairs so I can't do a head-to-head.
