See the follow up post... I'm keeping this amp.  

I'm looking to sell my Audiosector amp that was made from a Peter Daniels kit by me in late 2005 after I read a glowing 6 Moons review.  The review is still on line if you have plenty of time to wade through the BS.  

Peter Daniel was gracious enough to guide me as to the parts needed to mimic his Patek monos using fancy parts such as Blackgates capacitors and the proper resistor types.  So, this one has all the right parts to be similar to his beutiful Patek... except for the chassis.

I used a nice single Lansing chassis.  The toroid power transformers are the correct Plitrons.  The binding posts are WBT midlines.  There are two power switches with fuses requiring two power cords.  So, it's essentially a monoblock pair in one package.

I really enjoy this amp and it has been trouble free.  It made a great fit for a second system that I used sparingly.  I hate to see it go, but I really need to reduce my toy collection.  It's quiet and sounds really good.  Bass is its forte and has been used it with a SEAS coaxial transmission line speaker to good effect.  Cosmetically, the amp looks very nice and clean.  I think I can round up some literature for the amp as well.  

I'm guessing there are >$700 in parts, so I'd like to find it a new home for $400 due to its age.  I'll eat the paypal fees and the amp will be double boxed.  Just email  or PM me if you have interest or questions.

Here are a few photos.

Hey Heny, what's the input sensitivity? Will it work with The Truth and a "normal" output source?

Hey Ed, the input impedance is 22k.  I had never hooked the Audiosector to the Truth... and wow.  Thanks to your question and five minutes of plugging in wires, I'm keeping it. Grin

The Truth preamp and AS amp are in love.  I have no idea why this works so well.  Hooked to two other decent preamps, the amp sounded a bit two-dimensional and lifeless.. 

I need another Truth.

Don't discount your amps until the Truth is in the mix.

Henry, considering I've owed you one for almost a year..............it will be sooner rather than later Smiley.

I bet the 22K input impedance was a factor but  with The Truth that is irrelevant.

Ed
ps.....I was talking about input sensitivity (expressed in volts) not input impedance, it seems it is low enough!

BTW, I found an input sensitivity number of 0.6V.  That wasn't for this specific model, but was for a similar stereo version (Amp 1).

The Truth provides plenty of gain, more than the other amps I have used.
