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

Bombaywalla,

Any tube pre-amp recommendation mating my Threshold 4000.

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

Thanks.pescolar

looking at the specs only, the Cary SLP-98 looks like a good match. Anyway you can audition it/try it before buying?
Another person I know (who has a Threshold T series amp) uses a Music First Audio (MFA) passive TVC preamp & really likes what he hears.
An obvious match is what some others have already recommended - the Forte (down-market Threshold brand) & Threshold s.s. preamps such as Forte F-44, Model 2 OR Threshold FET-9, FET-10HL, T-2, T-3.

I wanted to clarify my post above. I contacted Nelson about my Stasis 2 and he informed me the following.

The input impedance is 75K. There is a 4.75K resistor and then a 10K resistor, the 10K has been bootstrapped to
a 70K value.

So the 75k reported looks to be the correct answer for both the 4000 and Stasis 2.

I have to agree that 75k input impedance is the right one.

I looked at the schematic, and a quick calculation shows 75K. The 15K value is
in error - the 10K value he is looking at has been bootstrapped to a 70K value. and
is added to the 4.75K input resistor before it.

NOW IT'S TIME TO FIND A TUBE PRE-AMP THAT WILL SUITED IN MY BUDGET AND IN A TIMELY MANNER.THANKS TO ALL PESCOLAR.

Bombaywalla, recently sold all my tube gears including Cary SLP-98 for financial reasons and now I am starting to build a budgeted system.I am familiar with SLP-98 and actually I kept enough 6sn7 and extras...will be a little cheaper if i decide to slp-98...but dreaming to have ARC too.if i have extra dough then ill go to all Pass Labs gears.
SO MOST LIKELY MY PRE-AMP 'S CHOICE ....CARY SLP-98.

Last Memorial weekend just happened in one of my friends party to auditioned a "DYNAUDIO AUDIENCE 82".

First time I heard this speaker and make me decide to go for Dynaudio Speaker ,now first choice.

HOW MUCH SHOULD I PAY FOR A USED ONE?

Any idea on the used priced market?Thanks.pescolar
