Other measurements....

It's a STOCK PL400? And still outputs 265 watts? I'm reading that correctly, right?

 

[laatsch55]

Correct Mark, at 1% distortion...

 

[laatsch55]

Listening to Skip's stock 400 right now. From the specs you would think this would sound like a WOPL, but alas it doesn't, bass is flabbier, a lot of sibilance ( well, more than we are used too with the Rev E board)...and I haven't even pulled the tranny covers to see if it's a quasi or full comp....


SOUNDS like a quasi though.....

The Shpongle flutes could elicit some listener fatigue......

 

[WOPL Sniffer]

Shpongle will show all weaknesses............... I hate a flabby bass... Unless you are talking about the fish.

 

[laatsch55]

Standard test tunes are Shpongle, Crystal Method and Moby.....with a little Patricia Barber thrown in....

 

[WOPL Sniffer]

I guess I need to get some tunes added to my library

 

[laatsch55]

On Moby---"Play" track 4, there is a LOOOOOOOOOOOng extended bass note that gets DOOOOOOOOOOOOOOOOOOOOOOOOOOOOOwn........


Crystal Method ----"Vegas" Track 4 has the same thing and maybe a bit lower

Shpongle----"Are You Shpongled" Track 6 "Divine Moment of Truth" is some very "crowded" music. A lot going on in that song.....at the same time, excellent test tune..


Patricia Barber.....You can hear her swallow the mic.....

 

[WOPL Sniffer]

I should be ready to test the 2 Clair's (WOPL's) I'm going to finish in the next 2 days, I'll run them across the dScope and then I may need to purchase some of those recommendations to give them a burn in/ear test.

 

[laatsch55]

Perry, they will show the weak spots...

From the pic I'm guessing it's a quasi.

 

[laatsch55]

From the bass alone I'm 99% sure it's a quasi. Don did I ever send you the meter I promised??

No, and I could still use it. Plenty of other things to keep me busy.

 

[laatsch55]

PM your address again Don and I'll get it on the way. I have to break up a set anyway, and I got to thinkin I hadn't sent yours yet....
