And of course this is supported by hard Science.

Since you are going from (relatively) no charge when you first play music, the dielectric needs some finite amount of time to get with the program. Is it a ms or a us?

Personally, I'd give it a whole minute, just to let all them electrons settle down.  You know how they get.

<SNIP>

It breaks in, but never wears out.  Gotta love that concept!

Shouldn't we be proud that our ears adjust, and not ashamed to admit it?

It must be the wire the changes...

It has happened to me a few times.  Install new premium cable - sounds bright.  Run system with power amp turned off for a few hours, listen again, sounds normal.  Darren at DH Labs told me that a chemical engineer buddy of his says there is something to the dielectric changing after a few hours use.  (How's that for hard science?) He also said that the ear getting adjusted is a possible explanation. (Hey, doesn't that presume that cables do sound different?) When DH Labs ships cable for review they break them in first.  I will explain all about it in my new book "Mastering Audio - The Agony and The Ecstasy."

Why is it always bright?  

Surely you don't expect any difference going in that might make the wetware more "sensitive?"

Or is the ear fair, and the brain flawed?  

That would suck.

Simple as that.  Who hasn't heard the difference, is what I want to know!

If you stay off the MDMA does it sound better, or worse?

Because both times it was the same kind of cable - with the cool teflon foam - the same kind Cardas was positing about.

Never touch the stuff. I won't even let a lava lamp in the place.

Yes, the 12BH7 RCA black plates replaced the GE 6414s and are a must. $85/pr. If I dont keep the unit they will be for sale

Besides the stereo buss what are people using the L2M on?  ... I tried a vocal and it was so, so.  Very even.  The TT CL1b was better (with Mullard and Telefunken), it had a euponic something.

Was that before you changed tubes?

Where did you source the RCA's?

They were 6414s ... Danny suggested the 12BH7As and I chose the RCA black plates after talking to Brendan at Tube World

I'd be curious to know what your impression of the RCA's with a vocal track is; if you get the chance.

Thanks for the tip- just ordered a Brimar pair from Brendan

If you decide not to keep the RCA's, give me a holler

Finally had a chance to do some work with my new (to me) L2M MKII today... although it sounds fine on first listen with the stocker tubes I may feel the need to experiment with some mods...

It's very red... and looks damn cool in the rack...

Let's be perfectly honest here

It's the coolest looking piece of gear ever made

It's like Ferarri red, you just can't beat it ...


I do have a problem matching it with bot my Lavry blue AND my Cranesong rig (especially the Lavry, makes me wanna upgrade to gold channel if you ask me)

we are worse than our wives

What's the difference between the Brimars and RCA supposed to be?
Please if you can share your experiences.
Brimars appear to be much more expensive than RCA's.
Also: are they both a direct replacement for the stock tubes?
Thanks.
Riccardo.

I have no idea ... call www.tubeworld.com

I think RCA black plates are the same as Mullards, but even that I'm not sure about.  In that era only a few factories made tubes and each one made maybe one type (or a few limited types at most) so the companies would swap labels and rebrand regularly.
