gonna disagree with some of the comments from earlier. although I do find the dac section to be stellar I think the amp portion falls behind. running balanced thru the ha-1 with my he-560 I lose some dynamics and micro detail vs my wa7(eh)/wa7tp(mullards). the extension falls short a smidgen on bass.
not a life changing difference but enough to keep the wa7 for sure. the value of the ha-1 still is good for what you get in one package but i just don't want someone thinking this a world beater like some of the impressions preceding mine.
...
I had the same setup with exception of the mullards..
I know exactly what is going on..
I have to disagree though. .
The reason is not what is lacking,
But what is changing.
The wa7&wa7tp combo deviates from the neutrality of the HA-1
The tube sound, coupled with an elevation in bass and dynamics makes it a seductive addictive combination,
But there is no way it surpasses the linear clarity and detail retrieval of the HA-1.
The wa7 combo is just a different presentation which is extremely impressive but not as true to source, as the HA-1 to me.
Edit:
I did sell and do miss that combo.. but I couldn't keep both at time..
