Current exchange rates for those curious about how much CAD100 is:

100.00 CAD Canada Dollars =
64.2960 USD United States Dollars

1 CAD = 0.642960 USD
1 USD = 1.55531 CAD

I just called R-Theta and asked for a quote on 100 and 150 pcs. I should get the answer tommorow. They would be shipping directly to US and shipping payment would be done on the receiving end.

Brian, maybe you could check the 100pcs. pricing on a similar extrusion from Aavid, so we could compare both prices and had something to bargain about.

Alright. I asked for a quote from R-theta yesterday to see how it compares to your quote from canada. I will submit one to Aavid today.

edit: I submitted a request for a quote on 100 and also 150 units. I also inquired about their 72355 extrusion, which seems a bit more robust (although, I like the look of the 65340 better):

Hey folks,

I have two questions:

1) Supposedly, using, say, 3 separate heatsinks for every channel will have better heat dissipation than one mega-heatsink like the one shown in the pic (i relate to it's size more than everything else) if the heatsinks will have a small distance between them it should be even better. If this is true (and i'd be glad to be corrected) why are you all going for those very big heatsinks?

2) Do you think R-theta will ship internationally as well?

Many thanks in advacne.

Cheers,
Guy.

I'm interested too.

I suggest that we contact M&M as well. I know that they were relatively very cheap compared to some of the others, when Wayne Sankey bought them for his Aleph 2s. He used extrusion 11645B and I personally think they look pretty nice. Picture below of Wayne's amps. I can't really imagine the quality being significantly different from the other suppliers.

At his price, it cost only US$120 for enough for a pair of amps. That's a great price.

Extrusion MK62430 also looks very good; a little more like the 'standard' we all think of (very similar to the R-Theta you folks are looking at). See drawing in the next post.

I'll be happy to call them about quantity pricing and willingness to make the individual shipments if you folks are interested in a comparison.

For what it's worth, the 11645 looks to be a bit more efficient in terms of sinking ability per unit width. .8C/W in a width of 7 in. vs. .6in a width of 12.25 in. for the 62430.
