Asking for guidance on my first hi-fi system...


Hello, this is my first post here and I am hoping to gain a little confidence in making a purchase of an integrated amp for a nice two channel music only system. I recently built my own speakers, (the Jim Holtz Mini Statements) and auditioned them at my friends house on two different high end audio systems.... Rogue, Electrocompaniet, Van Alstine are a few names I remember of his gear. He helped me confirm that my speakers sound very nice and are a good starting point to build upon. My budget is 500.00 or less for an amp. Currently I use an Onkyo HT-R520 home theatre receiver, set on "Direct" listening mode. Obviously, my speakers don't sound as good with the Onkyo. I believe the bass is over emphasized and the mids and highs are a little lacking in detail.
Here are my objectives:
1. Stay within budget
2. Find something that will sound better and resolve the weaknesses of the Onkyo

Currently I am interested in a 300 to 400 dollar Carver CM 1090 integrated amp. Would this be a wise choice given it's age? or should I be looking at a new NAD, or ?????

Any and all help would be greatly appreciated!

The first thing I would consider is how are your speakers "voiced"?If they are fairly neutral or slightly(or heavily)bright then NAD or Cambridge Audio would be a good choice but if they are warm/ish then I would look to Marantz (fairly neutral electronics)as the 2 I already mentioned tend to have a warm voice.Your budget will by brand new(instead of messing with older/used)& you will get much better build quality/sound.
Yesterday I received my NAD 326BEE and I didn't waste any time getting it set up and listening to some of my favorite music. I think I had a smile stuck on my face the entire time and almost giddy at times. I couldn't be happier with my investment in the NAD. With every piece of music I listened to I heard details that I hadn't heard with my Onkyo HT receiver. My speakers utilize a 4" titanium cone midrange driver and a 3" ribbon tweeter and they just came to life... The best way I can describe it is to say that my old system was like regular TV, the NAD makes it like HDTV... It's really that obvious and so much fun. The bass is just right also, sharp, solid and detailed. Thanks to all for the great suggestions !

One more question though, I assume it will break in to some degree... What might I notice to know that it has been broken in?

Thanks
You made a good choice with the NAD. The audio world is a better place because NAD can offer so much bang for the buck. Everyone hears differently so you tell us if or what differences you notice as it breaks in. You can be assured it will only get better if anything.
Always nice when people provide follow-up. Hope you get years of enjoyment with the NAD.
