a first integrated amp to build a system around

Speakers are the key at this level. I would consider the Magnepan MMG(new or used) or the Silverline Prelude(used). Look(might take some time) for a used NAD S300 or a Classe 151. Both these amps are of high(build/sound) quality even if there 10+ years old, $750 should be enough to find a nice unit. Save money on the digital front and consider a Sharp DX-670/770 or any Sony ES player, a nice working Sharp should cost <$100 and some Sony ES players can be found for <$200. Cables are important, Signal Cable Reference(silver)can't be beat when regarding price. With this set up only the CD-Player will need to be upgraded when your ready to improve your system.

Without sounding scolding I also agree that system building starts with speakers. They are really definitive in the way your system will sound. If I had to choose the non speaker parts I recommend buying the Music Hall gear. I bought my first "higher end" system over a dozen years ago and bought an MMF25 CD player. Post divorce I am listening to it now, no issues. In the end it is better to pick the gear that your speakers work best with.

This is the kind of advice I was looking for. Thank you.

Would help greatly to know what sound reproduction characteristics are important to you, what type of music you listen to and how loud, etc. That said, agree with others that speakers are the place to start and then choose an amp that matches sonically with them and that can drive them properly. Then go from there. If you don't get speakers you love you'll never truly love your system, so do whatever you need to do to get that right.

If you lean more to classical, acoustic jazz kind of music where imaging, soundstage, ambient cues, etc. are important I second something like used Silverline Prelude or Minuets. Very good all arounders that can do the audiophile nuance stuff well. If you're more into loud rock and need slamming dynamics something like the Tekton Mini Lore or one of their larger models used would be a better choice. Anyway, as others have said, it's best to go out and start listening to some speakers with your music so you can start to identify what you like and so you have a more defined idea of what you're looking for. More useful and productive than reading our blabber IMO. Best of luck in your search, and have fun with the whole process. You'll learn a ton, which makes it even more fun.

when you get around to re-looking/listening add the Peachtree series to your list. 65, 125 or 225.
