Very Cool!

Will the mono output be available on the upgrade?  I prefer that to the headphone output.

Howdy Ray,

Check your PM .....  :)

  My CSP was the guinea pig.....it will be here tomorrow....I can't wait!!!

Randy,

  I sure will give all my impressions. I'm finally getting my new room close to being finished. Its really sounding  pretty good right now, it has a way to go for tonal balance, I worked on bass traps tonight, still have a few more to build, but I feel I'm getting closer to a great listening environment.

 My CSP is in the original silver chassis which was to match my Select monos built in the silver chassis, which is why I wanted to stick with it in the old style as well.

 I can't wait to hear about your new acquisition.....

surely there must be previous owners of the CSP who sold and bought a CSP2 prior to this upgrade being released?  What say you?  What difference(s) do you hear?

[quote author=Steve Deckert  link=1169506099/0#0 date=1169502499]Finally, we are now able to offer an upgrade for CSP owners that changes it to a CSP2.  

A little background:

You would think that building the CSP2 circuit in the CSP chassis would be a no brainer, but this is never the case when chassis and layouts are changed - regardless of the circuits - at least in my experience.  Besides actually changing how the circuit sounds, often noise and or hum issues have to be dealt with any time  a drastic change, such as a chassis, is undertaken.

This was (as expected) the case when the first CSP to CSP2 upgrade was attempted.  It has taken a considerable amount of time to re-engineer the layout and grounding scheme to achieve the same net result as just buying a CSP2 in the first place.  We are after all dealing with a steel chassis (CSP) vs. an aluminum chassis (CSP2).  The steel chassis are magnetic while the aluminum are not.  This completely changes the eddy currents that are induced in the chassis from magnetic fields and consequently the grounding topology.  

ANYWAY - it has been done successfully and I now know what is involved time wise and what the end results will be.

PRICES - The mod will completely gut the inside of the CSP and rebuild it as a CSP2.  The costs are as follows:

Convert CSP to CSP2 without headphone jack is going to be $275.00 - not the $400 we projected.  This is thanks to our expertise and skill at soldering.

Convert CSP to CSP2 WITH headphone jack is going to be $325.00.


RESULTS

The changes you will experience are as follows:

A richer sound with more weight.

A better frequency balance with less midrange and treble highlighting.  

Better overall musicality.

10dB more dynamic range at any given volume level.

10dB lower noise floor.

Lower THD by a full decimal point.


WARNINGS

If you are interested in the headphone option you should understand up front that like the CSP2, the headphone ouput is killer good sounding on anything from Grado 32 ohms to Sens at 600 ohms up to a normal listening level (1/2 volume on the volume control).  It will not get louder then that with headphones without distortion, so if you like headphones to be on the loud side you will probably be dissatisfied.

If you have no plans to use headphones then get the mod without the headphone jack.  The line level outputs will actually sound about 5% better then if the headphone option is added.

Does this mean my csp will look like the new csp2? you know, new chassis and the wood frame?
