Hi does anyone know if their is a difference in sound between the wa-5 and wa-5le first (but also second) generation?


There's an article comparing the 2 over at The Part Time Audiophile by Scott Hull, sorry don't have the link handy

Do you own the 800's and LCD-X

 
No. I own LCD-3 and X.
 
However I have done extensive listening to Tony's modded HD800 on his and my gear.

Hi everyone,
I just bought a used WA6 for my grado's and some how I feel the bass is too distorted.
Sounds like I am listening to high gain amp.
Currently I am using only stock tubes.
Do you guys think switching the Rectifier to Sophia princess will help?
Some say I also need to switch Driver / Power tubes too.
Any suggestion? I need to bring back the tight bass of grado's.

That looks like the problem right there. The stock tubes are often underwhelming, to say the least.
 
I would look to upgrade the tubes to something like Brimar rectifier + NU 6F8Gs (for example). That will lift the WA6 performance several notches. There are plenty of other tube options out there - this one works for me.

Several posts ago I said I wouldn't buy the NU-6F8G's again (although they are fantastic) due to them being very noisy in my WA6 (which I thought I fixed with Deoxit…didn't work) and none of my other tubes were noisy at all. Well, last week I ordered another pair

  (I should never say never again) from a seller in the U.K. ( NU-matched 1942) and needless to say they are dead silent! This entire time I was having issues with the first set I bought…should have returned them for my money back instead of accepting replacements in the first place.

I have rolled and own a few sets of NU. Never had a noisy one.
 
I know the 6F can be noisy in the WA5 however that is fixed by using the 6C.

I should have pointed out there is some risk with the NUs. Roughly 20% of mine have been noisy in my WA6.
 
When not noisy they are superb sounding, but there is always that risk.

I guess (well I now know) that unfortunately I got a bad pair…twice because the first ones were exchanged. But like I said these are dead silent…thank goodness!

I don't know if anyone has tried Type 80 and #83V rectifiers. The top row shows a number of Type 80s from the 40s to the early-60s GT bottle with a 1275 (ST shape) on the far right. It's a lower powered version of a Type 80.

The bottom row shows a pair of #83V and a Brimar 5Z4GY and TS6AS7G for scale. From what I've read, the #83V has the lowest Vdrop after a GZ34, I've found these rectifiers to work best with 6CY7 and some make a synergistic combo with 6EW7, albeit without the fireworks of a 6CY7. All in a WA6.
