6x4 rectifier question


Is the 6x4 in something like a Lamm LL2.1 or LP2 going to affect the sound much if you roll in different NOS types?

Thank you for this. I'll order one and compare.

I did some research and I ended up with a Sylvania 6X4 green printing with the triangle logo. $15 and better sounding than the Mullards I had previously in my LL2.1 and LP2.
@couger4u , on your suggestion, just sought out a Brimer EZ90 from viva tubes for my Lamm, installed and can't express how much I love it. Thank you. Enjoy the music
I have found NOS BRIMER 6x4 England EZ90 Black Glass Smoked Vacuum Tube as the best. I am using one in my Eastern Electric Avant preamp. It is a little pricey but worth it. 
Just a suggestion: NOS Mullards are typically the best sounding (according to most opinions) and longest lasting rectifiers, extant.                 Especially; those from the Blackburn plant.              ie: http://tctubes.com/Mullard-EZ90-6X4-tube-1.aspx     and:   https://www.tubemonger.com/Mullard_CV493_6X4_MINT_NOS_Blackburn_Gt_Britain_p/1212.htm          Don't know if there's much diff in sound quality/presentation, between the D and square getters, but given the low prices; I'd try both..
I would say yes, as mentioned above the rectifier tube is where I normally get the biggest upgrade. I own a Lamm LL2.1 Deluxe, haven't swapped out the rectifier in it as of yet as there didn't seem to be a lot to choose from but did change out the 12AU7s to the Psvane Premium grade 12AU7T II tubes and really like them. Enjoy the music
Probably. Changing the rectifier tubes on my power amps make an easily-heard difference.
