1) I read in this forum that higher density fiber glass materials are better for sound absorption. But Alton Everest in his "Master Handbook of Acoustics" (4th edition pg 192) points that density does not matter as long as it is not very low. Could some one shed some light on this.

Could someone help me appreciate the meaning of the words used so frequently in reviews:
Transparency, Warmth and Neutrality, Can a sound from a speaker be neutral yet not transparent or warm?
I understand that these are subjective I will be happy with any possible help.

I'm generally very happy with my Rega P2.

I had the guys at the store (high end audio store) install and align the cart. On two brand-new records, I ran into the dreaded 1.8 second repeat. The first time, I thought it was a bad record, but when it happened on another one, I decided to increase the tracking for a little to see if it helped. It did. (By the way, it ocurred in the exact same spot each time, so there must be something on the record throwing it off).

See JV's comments about REG on P.106 of the 8/08 issue.

I've been reading most of your articles on your site and I was wondering: Do bass waves (in general) pass through anything not truly solid (like a table or a cabinet)? Like for instance would they mostly go right though a sofa? I'm curious as to whether one could put some bass traps behind a sofa or chair for instance. I know upholstered furniture can reflect and absorb various frequencies (mine is fabric BTW and not at all overstuffed) and I have about 6" behind it and the wall where some bass traps could be discretely placed, if of course they'd do anything back there.

I saw that mofi was re-issuing Metallica albums, and just got the Master of Puppets special edition in the mail. I'm at work, so I haven't gotten a chance to listen to it. What is already frustrating is that the inner sleeves were already split slightly (as occurs when someone drops a record into a sleeve), and there are very light scuff marks. I can only see the scuffs under the appropriate light, and I doubt it'll affect the sound, but I'm contemplating getting another copy. Really a bummer. Brand new, sealed record.

At first I thought you were kidding.

What are the absorption specs for this little guy?

(Sorry Stephen. I forgot that we are not supposed to directly respond to product announcements.)
