SF Extrema,Few q


Hi there,

I read a lot about this speaker ,a lot of people saying its the best speaker ever,but also mention that it really hard to "push" and if i buy it i need very expensive amp and source.
I want to know why it have to be that expensive ,Is there strong AMP that can work good with the EXTREMA without being very expensive (for me >3K its expensive)?
Nuforce,CI Audio and etc arent expensive and i heard they can kick!
Is anybody know how this speaker work with CLASS D ?amplication?I read that tube isn't good for this speaker.

for Those who have/had it:
What do u think about this speaker copmaring new speaker around the 5K?is it good invesment?after all the speaker old (14years).
Thanx a lot!

That's are really difficult question to answer. None of us knows all of the 5k speakers out there, Scubi...

Anyway, the Extrema perform very well. Despite their age, many other speakers will not perform better within the Extremas' optimum operating range...
They were also very expensive speakers. If you're ready to buy a used pair, make sure the drive units are in as good a condition as they can reasonably be. Is this pair expensive?

They do need a powerful amplifier. I don't know if a digital amp will do the trick -- why not? In fact, instead of purchasing a branded product (Nuforce etc) why not diy and buy from Hypex in the Netherlands ($~300). I used a standard SS amp when I used them.
Cheers
I use a Audio Research D400mkII (400wpc/4ohm) solid state amplifier that I purchased used on A'gon for around 2K. This amp give me the best of both worlds smooth, airy and guts!!! This is a great amp I feel for any speaker that need lots of current. I've thought about buying another to run mono. Truly the greatest speaker I've owned...

Good Luck...David
as Gergm advise to check the units condition I guess the following Q has to be if SONUS FABER still holding repair units for the Extrema?after 14 years i think they may not.

Gregm - To build good AMP based on Hyepx it will cost me much more than 300$ maybe around the 1400$(!),I guess second hand will be more easy for to buy.
have u heard hyepx DIY amps?do u think it can be good match?
