Soundstage is constricted on the LCD-2. It's better on the HE-6.
The HE-6 are much better than the LCD-2 in detail resolution.
The T1 are somewhat better than the HE-6 in soundstage and imaging. Pretty similar in tonality and detail resolution, although I slightly prefer the HE-6 on that front.
All of these pale when compared to top Stax setups. The SR-009 is in a completely different league all around in my experience, but it's also much more expensive. The SR-007 is also more expensive.
At the price level of the LCD-2, I would go with the HE-6 or T1 instead.
