Lamm 1.2 vs. Pass xa 60.5

Hi, Icorem those G3 speakers looking at the Steophile test measurments have a current hungry bass, 4ohms and -40 degrees phase angle, also they need watts as well at only 86db efficiency.
I think the Lam's maybe be a bit of a sideways step, if you look at the Stereophile tests on both them and the XA-60.5, as there's not much difference in watts and current.

A suggestion as well if you want good current, bags of watts with the class A sound of the XA60.5. For the price you get for your XA-60.5 you could get a pair of these.

The John Curl (he's up there with Nelson Pass) designed Parasound JC1's will drive anything you can throw at them, even the impossible to drive at their best "Wilson Alexia's". I think they are the best value in big amps.
As you can see below, the watts just keep increasing with lowering impedance, this means they can give great current drive into any load and remain flat in frequency from 20hz to 20khz, instead of acting like a fixed tone control, like some wimpy amps do.

Tested at
8ohms=545watts
4ohms=1154watts
2ohms=2255watts
1ohm=4200watts

They also have one nice feature that let you switch them to much higher 25watts pure class A, still with 545w a/b for transients, (they run hot in this mode)which is good when you listen seriously, then you can switch it out to the lower class A bias, for dinner/parties or background music, and this will save the power bill and they run luke warm.

Thanks so far guys - appreciate your high value points.
Yes, I'm afraid moving to the Lamms will be a bit of a sideways step and I don't have a chance to audition. I also have the option of trading the 60.5 to a 100.8
ahhh - those tough but much needed decisions...

The .8 series should be a big improvement. I had the 100.5 as well. But I will choose for a 350.8. Because it is more airy than the XA series. And the better speed and drive also will work great with your speakers.

I had a few discussions with the Pass Labs people about cables. Powercables like the Purist Limited Edition sets Pass labs to a much higher level. I could achieve better level in articulation of voices and a much wider and deeper stage with the Limited. I heard many new things which I did not have witht the XA100.5 with cheaper powercables.

Go for a 350.8 and a Purist Audio Limited powercable!!

The Purist Limited makes the mid freq of the X series sound the same as the XA series with other powercables.

First I owned the XA30.5, 60.5 and 100.5. I thought I never would choose for the X-series.

The Purist Limited Edition made me think totally different.
Most powercables are not able to get the maximum out of an amp. We are not talking about a few %, it is a huge difference!!

Bo
when will you get the 350.8 ?
I'm waiting for your impressions against the 100.5 !!
