i have been research entry level hifi for a month now. time for advice as purchase time is drawing near. i am having trouble truly understanding the basic difference between receivers and integrated amps. i am not rich and im not and AUDIOPHILE per se. i do enjoy quality and clarity. up until now, my stereo experience has been composed of mini systems, mp3 players, and i did own a sony rack system about 20 years ago. i dont think i have ever own a stereo where u wouldn't hear static at half volume. i am at an age where i wanna treat myself an invest in a little quality. i wanna experience my music not just listen to it. i looked at hk3490 as it has digital inputs and gets good reviews. it also boasts 120 wattsx2. i looked at integrateds like the pm5004 from marantz, azur 550 from CA, and the 315bee3 from nad. all are around 40 wattsx2. i dont get the huge wattage disparity? can u help me understand? i havent read alot about building a system around a receiver so that must tell me something. i use my pc a lot so the digital inputs interested me. but it's no deal breaker. as u can no doubt tell, my quality desires have a price range lol. i would love to stay around 500.00 for my amp/receiver. as i stated. NOT RICH. i would go a little higher and maybe start off with cheaper speakers like the paradigm atom's to buy a better unit. and just upgrade my speakers later. i hear the atom's are really good for the price. i would like to eventually pick up a pair of studio 10's. and add a powered sub for the low's. i have read a few places that certain speakers pair well with certain amps. i.e. b&w with rotel. is this true? okies. that's it in a nutshell. any advice would be greatly appreciated. i need advice on an entry level amp/receiver and opinions on the studio 10's or advice on a better pair of bookshelves. tyvm for listening and helping.
