Help need speaker to match Threshold 4000 amp....

Yesterday I got few minutes late.There was a Lector Zoe came out for sale at Audiogon for $800 ...Ht by pass not working...anyway I think I am going to ARC pre.
Ferrari, i will check n read regarding ARC SP8 & SP10 and read more.I have to be carefull on choosing what I want.So I won't look back any more and then find the speaker for my future system.Any feed back on Dynaudio Contour SE..never heard of it.

Ferrari are you close to Brentwood right?

Thanks.pescolar

watch out for the really high output impedance of the ARC preamps that might make it very diff to mate to the very low inp impedance of the Threshold 4000. The result will be very lack-lustre sonics.
FWIW.

Bombaywalla,

Any tube pre-amp recommendation mating my Threshold 4000.

How about Cary Slp-98 (output impedance 400 ohms)

Thanks.pescolar

Can anyone have any information about the input impedance of Threshold 4000..I am trying to google it and no luck yet.

Mr. Jon Soderberg ( nice guy) e-mailed me almost a week now and told me Threshold 4000 amp input Z is 15k.

Is there anyone out there can explain or how to match the right number for the pre-amp out put?

Thanks.

I use the ARC SP17L with my Threshold Stasis 2 and like what I hear.
