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

Love these authentic FP moxie jeans
Size: 29, Color: Truest Blue
I purchased two pairs of moxie FP jeans on Amazon both on sale. I love how different they are. The paint splatters are just the right amount in my opinion. I think the barrel leg is just wide enough without being obnoxious. I like an oversized look and these were the right price for me on Amazon. I love the rope waistband on these too

“Gorgeous Color and Great Fit”
Size: 9, Color: Atlantic Blue
I absolutely love these Sam Edelman Bay sandals in Atlantic-/Tide-blue. The 9 M fit me perfectly — true to size and very comfortable right out of the box. The leather is soft but sturdy, and the slide design makes it super easy to throw on for errands, brunch, or just relaxing around town. The footbed has enough cushioning that my feet don’t feel tired after a few hours. Overall, great quality and style, and they look more expensive than they really are.
