Jubilee's in Richmond VA, who might like to help setup and listen?

I personally would use a sinewave for the test instead of pinknoise since the level won't bounce around the way pink noise will. Also, you should really have your speakers connected to the amps when taking the measurement, but that's getting real nitpicky, and can be dangerous for the tweets since all of the filters and xovers should be bypassed during the measurement.

Mike(Who) I had talked to David on the phone and told him he could use a sinewave but I've used both and prefer the 1/3rd octave pink noise and level bounce has not given any issues for me but checking it both ways would be fine if he likes.

"(4) Connect the channel for testing of each amplifier to your LaScalas."

I also talked to David about having a common type load (ie: LaScala, Jub LF, or 8 ohm resistors) for the test channel's measurements. Having looked at the manuals for Davids amplifiers I believe in his particular case he will be fine if the undriven channels (channels with no signal applied and not used for the test) aren't loaded.

(Note) If an amplifier's manual cautions that it should always have a load connected to it's outputs or if a person is just uncertain then of course an 8 ohm 20watt resistor or another loudspeaker can be placed on the unused channels during testing just to be on the cautionary side.

Also Mike(Who) the EV active crossover want even be in the system for this test since it's purpose is to find the correct input level adjustment of the Crown K2 to match the MC402's input sensitivity.

Ok guys, finished building my component shelving for my living room.

The jubes should be here early next week. More pics to come.

And here you go guys. I still have some wiring to do for video, but I do have the music up and cranking. Unbelievable is all I can say. K2 running the bass bins and Mac MC402 running the tads. Tads hitting 4 watts and god knows how many watts hitting the bass bins. It caves the chest is all I can say.

I have never been one to sugarcoat anything. I bought a brand new set of La Scala II's in 2010. The finest sound I have ever heard a system to be. I questioned many people on this site about really how much better can a system sound with the jubilee's than what I had. All I got was "trust me" and " you have no idea". I had reserve about it. But as everyone knows on this site, we all seek the next level. I have skipped levels with this addition. My opinion as well as a couple of friends of mine that share the music hobbie, the jubilee's are about 4 or 5 times the sound I get with my La Scala's. I have never heard what I am hearing right now with only 4 watts of power on the HF. Period. If anyone has any questions or comments for me, I will be glad to take them. Many thanks go out to Mike and Richard as they have been very helpful in this LONG journey. And yes. It was worth it!
