GS1000 did not sit well with me - I thought they were too non-linear - had too many peaks and dips (for my taste) - so I sold GS1000 but for whatever it is worth - GS1000 sounded better than ever through WA5. As I understand, WA6 - provides a nice slice of WA5 performance. Maxed out WA6 sounds like a good amp for any headphone.
For me, AKG701 amd AKG1000 were, by far, the best sounding cans through WA5
I recently received my Woo 5 LE (with upgraded V-Cap .15/600V and Jensen 220u/450V) and I listen primarily through the GS-1000s. For 90% of recordings I simply can't imagine a better headphone. Each of the sonic attributed that I love - e.g. speed, dynamics, tight and produgious low-level extension, vocals and HF detail - seem to be there in spades.
I recently had the GS 1000s recabled with Stefan Art Equinox and the phones are sounding better than ever. Although I'm not an experienced tube'r I did a fair amout of research to settle on a what I thought would give me the sounds that I wanted (Sophia Princess Carbon Plate 300Bs, Ken Rad 5U4Gs, RCA VT-231)
With my source I tried to go for as analogue a sound as possible (in the digital world) with an Altmann Attraction DAC and Audionet ART v2 Transport. Spent some good money on vibration reduction, interconnects, power, etc...
I've tried to create a good environment to bring the best out of the GS-1000s. I believe that the Woo 5 is a stellar partner with the phones I have tried (x2 to Saisunil). In most music scenarios, the GS 1000s really are magical with this amp. And for me the GS 1000s are so nearly the phones for listening to all my music types (mainly folk, electronica, rock, pop). I have not, however, been able to say that I am truly happy with the high frequencies. Some of this may be me - I think I am very sensitive to HF and can be fatigued by peaks that other people find absolutely fine. I have handed the phones to a couple of my friends during passages where the HFs mean I simply have to take them off; they have no such issues at all.
It has made me think more about the inherent variability in how people process sound, and perhaps it was unrealistic for me to expect that the addition of a great amp like the Woo 5 would make me happy with the GS 1000s for 100% of the time. I've come to the conclusion that I just need to add another set of phones to accomodate this small idiosynchrosy (both in the phones and my own hearing). The difficulty is which other set of phones can please alongside the GS 1000s? I'm leaning towards the AKG K1000s as the obvious choice, but am going to do a little more searching around. Having never heard them, I don't know I will be any less susceptible to HF fatigue with them (It would be good to get a few opinions here). Having read Saisunil's view that the k1000s were 'by far the best sounding cans' through the Woo 5 I am deeply tempted to pull the trigger on a well-priced pair that have been waived under my nose.
Guess there is only one way to find out.....
