1 TOTL amp specifically made to drive each flagship headphone is the ideal. The WA5 / HE-6 combo is great though, especially since WA5 can do speakers and other headphones really well too. Allnic HPA-5000 with HE-6 is incredible though too, I miss having it around, the WA5 is just missing that 2%, like 2% vs skim milk kinda thing.![]()
for HD 800 / HE-6 though, yeah tough to beat WA5, I've been using WA5 more for my speakers now though
Have you tried driving the HD800 via the speaker taps on the WA5 via a HiFiMan adapter box (or similar)? For me, this beats the standard HPH output of the WA5 significantly. Dynamics improve noticeably.
This doesn't work for the HE6 - the K1K output remains king, but I find that socket unusable for the HD800 due to the high noise floor (loud hum).
If you have access to a bigger and better tube amp you can get better results. I have an 845 based tube amp that I was using to drive speakers before replacing it with an Accuphase power amp. I now use the speaker taps of this 45kg beast to drive headphones. 20W of SET power driving the HD800 is quite something.
845 SET amp speaker taps >> WA5 speaker taps >>>>> WA5 HPH output
For both the HD800 and HE6 I am finding the Simaudio 430HA superb.
I slightly prefer it to the (WA5 K1K + HE6) and (845 SET + HD800) pairings mentioned above.
My HeadFi buddy prefers the 845 SET driving the HD800 - it's a close call. Both take the HD800 a very long way.
Do you know the sensitivity of the speakers you are driving with the WA5?
I had an expensive journey along that path. My floor standers are 88dB sensitivity - roughly average for a speaker, I guess. The 8W of the WA5 speaker output was just inadequate - like a poorly amped HE6 - thin sound and weak bass. The 20W 845 SET amp did a much better job and I was happy enough with the sound, but the heat coming from the 845 SET amp was insane for regular use, so I went with a nice solid state power amp (Accuphase P-4200). Only after hooking up the SS power amp did I realise what I missing out on due to the inadequate power of the 845 SET amp. Dynamics and bass took another big step upwards and sound is now excellent. 20W isn't enough to deliver the best from 88dB speakers , despite what some tube-heads might suggest

Happy to have found a use for the huge and expensive 845 SET speaker amp - it drives headphones like the HD800 stunningly well via an adapter box.
I have learned that speaker taps are not just for the HE6. Other headphones can benefit from the extra juice - highly recommended for the WA5 + HD800 combination.
