Gallo 3.5 or Martin Logan Ethos?


I am in the market for a new set of speakers and have been considering the Martin Logan Ethos (used, would also consider the Vantage or the Spire). I have not heard the Ethos but I have heard the Spire, Vantage and the Theos (similar to the Ethos). I really like the wall to wall soundstage that the Logan's create. My only hesitation is that the "sweet spot" is somewhat limited. I have read that the Gallo's have an ESL "like" presentation with a wide sweet spot. Has anyone compared the 2 directly?

How would you describe the pros and cons of each?

I am coming from Klipsch RF-7s for a frame of reference.

Macallan 7 (did you ever have the 50 yr old?) anyway....I never liked Martin Logans... I knew the guys there who are very nice, but I would choose Gallos.
What do you like better on the Gallos? Also is the sub amp necessary? I would power them with a 200 watt B&K and have a sub for low bass.
We had a brief discussion on the use of the Gallo SA Amp in the following thread (starting on page 97):

For more detailed information on the Ref 3.5 and its development see the 6 Moons archive of reviews.

I own the Ref 3.5. I never heard a Martin Logan model.
Thanks for the response on the SA amp. I also have read good things about the VR-33 in this same price point. They also have a wide sweet spot.
The Vantage and the Gallo are my 2 choices. Like the Vantage but have never heard Gallo. Anyone hear both? Or at least gallo and Logan's in general?
