Default Anyone one tried AudioPower.it yet?

I'm looking specifically at the SDA-300 kit, maybe the SDA/MDA-400 as well.

Cheers

ME!!!
I have at work a couple of sda400 Of...plus DPS 400...actually they work in mutiamp configuration..on my ribbon tw. (HIVI RT2Pro)
Great work IMHO..very transparent and detailed..a lot of power..of course.
Just FYI..in my "old" passive way..i'm driving the loudspeakers with a couple of Nuforce ref 9SEV3 (now placed on the medum Horn).
Bye..and..forgive my terrific English

Not at all at listening point..maybe e very little little noise at about 15 cm (measured) at full power without signal.. (remember..the amp goes direct to the tw..no filter between amp and driver..)
Take a look to my Hi End envelope..

I checked specs on your tweeter: 99db/W. Your noise report is quite promising then. (I have 113db/W compression tweeters)


Do you happen to have any subwoofers to test the SDA-400s with?

Thanks

Hi,
Nothing to worry about, shop & service running.
in a few moments, the AP site, show a message for customers.
We have had a profound problem with the large database, at the launch of some high-end models, with a new page dedicated virtual.
I take this opportunity to communicate a new shop dedicated exclusively to the American market.
will be online within 48 hours.
Although I am not directly AudioPower, I apologize for the inconvenience

Thank all.
Regards
Roberto P.

Which one do you prefer, nuforce ref 9sev3 or the audiopower?
Quale dei due preferisci, qualitativamente?

Hi Cyan
IMVHO you can't compare a commercial finished hiend ( really hi End) gear like Nuforce Ref9V3 SE with a little amp bundled with a power supply (Ok..a superb little amp with a superb power supply..)..I'm owner of Nuforce gear from beginning of the story..and, really, i love my amps..But i've switched to multiamp in my sistem and, of course, i can't afford to 7K * 3..unfortunately..So i've found these little jewels and, happily, i've found also the perfet match with my ribbon tweeters..these "toys" are deadly silent..with an incredible resolution on high freq (better than Nuforce..maybe..maybe for this point of view)...so..im' very happy now..and the ref 9 are still with me....
So..if you can, for a "normal" crossovered speaker and the price is ok for you..you can go for Nuforce for sure...but, maybe, we have to wait for news for "some high-end models" from Audiopower..

Again..sorry for my english...
