EML is better if you listen to "soft" music. Sondstage is better, and have more air than any other NOS tubes. They do bass, they go deep, but it is the "clean" and "little lean" kind especially mid bass. The bass impact with WA22 EML maybe well enough compare to other amps. But WA22 is capable hiting harder. For people only listen to classical, vocal, and even classical rock (beatles like), etc, EML is better. For people like me always want to rock out and listen classical, and vocal on the side, EML is ONLY not worthy its price tag. I just do not want people to missunderstood my review.
Since I only have HD650 which is known for have more bass than HD800. For HD800 owners EML less impact issue may become bigger problem there.
Correction: I misjudged the 53KU/CV378. that was a mistake I shound not use different CD to do the review, and should use old CD that I have listend 100+ times. They are not as good as once I put old CD in. I am very sorry about this, because WA22 sound so good, I often easily lost in the music. Still Mullard GZ34 offfers most impact, but sound cool, user beware. 5AS4 still hanging on good.
I ordered 5Z3 made in Italy, that is going be fun.
6F8G and 6FG7/6FQ7 I have used for long, the review is very accurate, do not worry.
