The QUANTUM QL amplifiers in the ESX Portfolio are technically the small siblings of the QUANTUM QE models. Ideally, they can be used where the installation space is very tight. They are also emission-free and, like the large QE models, have the finest Class D technology on board, which leaves nothing to be desired in terms of performance, sound quality and setting options. The QL models are also coming with the space-saving remote control.

Excellent shoes - good fit, nice look.
Excellent shoes - great value for money! Attractive and well built. Got several unsolicited compliments from co-workers. They are stiff at first and require a bit more of a break-in period than some other shoes I have purchased lately. I hope that is a sign of durability ...

Quality!

Stylish and most importantly they are comfortable right out of the box, no breaking in required. This is my second pair, I now own both the black and brown colors to compliment almost any outfit. Worth the price!

Absolutely comfortable.
Size: 9, Color: Brown Multi
I am always on the lookout for a professional, but very comfortable shoe (education field with a lot of walking). These Florsheims fit the bill and make me wonder why I never bought these before. Something about them just didn't "look" comfortable to me but man was I wrong. These are easily among my most comfortable work shoes with the bonus of also looking more professional. I will say they have some heft to them, so if that's a problem for you these may not be right for you. As for me, they are right as rain. I purchased the black and brown ones (with white souls) and they are at the top of my rotation now. I look forward to trying some more from Thai company.
