This is a great value RAM upgrade. I bought it to give my early 2011 MacBook Pro 13 inch. The RAM is significantly cheaper than what you'll pay Apple and, as far as my computer is concerned, every bit as good!
I bought these to go along with my Cambridge Audio Topaz Am10 amplifier. These are the first set of speakers, for the first ever hi-fi separates system I've bought - and I'm glad I got these! I have them hooked up with some QED Silver Anniversary XT cable and the sound quality (to my ears) is just as good as I get from my Bowers & Wilkins headphones. I'm happy!
All my hi-fi cables are made by QED and so far I've never been disappointed by the quality. The Profile series of interconnects are, in my opinion, some of the best priced, sturdy and quality cables I've ever used. This cable is no exception. I use it to connect my MacBook Pro to my Hi-Fi amplifier via a Cambridge Audio Dacmagic XS. The 3 meter cable allows me enough to sit on the couch whilst connected to the amplifier... bliss!
