Adcom gfa 555 or 5400


Hi, new here and new to the stereo hi-fi world. I'm looking to get my first separate amp to run my two front speakers off my Denon 4400 a/v receiver. So did some research and heard good things about Adcom, and their prices seem pretty affordable for a beginner. I have a chance to buy either a 555 or a 5400 both for about $300. My speakers are Monitor Audio silver 8's. The 555 has been with the seller for ten years and he says its running great, while the 5400 is being sold by an audio technician and he claims that he's just serviced it and that its also running great. I'm not looking for booming bass....just a nice warm clear sound from my two front speakers. Can anyone point out the cons/pros between these two older Adcoms, I know that the 555 has more power, but I'm more interested in the musical aspects of either amp. Cheers and thanks!

Vinnyjr,

That amp you found looks like a solid choice, and I’ve heard that the Zpre is good bang for buck.  As long as it has the bypass.
 Good luck with your search.
The Parasound Zpre has HT pass through.

call Safe and Sound, they sometimes have it as ‘b stock’ for about $330
The current model Schiit Saga+($399) and Freya+($899) have home theater bypass. It is a free feature all of their preamps have. I recommend the current model preamps because they shut down the tube buffer when it is not being used. Instructions at the bottom of the page:

You simply select the input, put it in passive mode and turn the volume all the way up. Instant 1:1 home theater bypass with only a relay in the signal path.

I realize that the Saga+ is a little out of your price range and the Freya+ is way out of your price range. Part of "saving money" when you are just getting started out is sometimes buying the right product the first time around. Buying something that serves your current needs AND your future needs can save you a lot of time, money and headaches in the long run.

Before you buy a preamp do some research and explore the advantages of having XLR inputs and outputs available to you. Balanced is the way to go if you want better sound quality and compatibility with more equipment.
For what it's worth, I had a long conversation with an experienced speaker designer, and he really likes the Parasounds (including the small light NewClassic 2100) as well as the Hint 6 (more expensive) and the stuff by Belles. He is really happy with the Van Alstine SET 400. FWIW.
