Preamp Suggestions??


Hi. I've recently begun moving from the "big box" crapiophile-level equipment to mid-fi audiophile equipment. I am a 2-channel listener only, so no A/V needs. I currently use an Adcom GFA-555 200 wpc power amp, an Arcam Alpha 8SE CD player, an Adcom GTP-500II preamp/tuner, and KEF Reference 103/4 tower loudspeakers. I use fairly nice Audioquest solid speaker cables and interconnects (Glowpower Zyxt interconnects from preamp to amp). It has been suggested that my next step up the hobbyist ladder should be to upgrade the preamp & move to a separate tuner. Again, this is just hobbyist fiddling, as the system sounds great as is. Is there a particular standout in the budget (under $500 used) preamp market?? Many thanks.

Onix SP3 Melody. Beautiful integrated amplifier.
I saw at least 3 in your price range. There was also a brand new model from certify dealer for $500!!!!
Here is the link to Srajan Ebaen's review on *6moons*

Or if you want something just a bit different sonically and visually , check out Promitheus Audio TVC SE for less then your budget but it's the passive preamp only.

Here is some information:

And maybe this one too. It has headphone amp and USB for connecting your computer. It might have enough muscle to handle your speakers but read the review first.

Glow Amp One (in your budget. Integrated)

I see one in the classifieds now for dirt cheap. I'd look into it. Check out the 6Moons review. Here's the distributer's website with a tiny bit of info on the SP3: http://www.melodyhifi.com/SP3.html
As one poster mentioned, going to a tube pre will help, but the Adcom 555 needs to be cleaned up to gain some real benefit.
The 555 is fairly easy to work on. Unscrew the top cover.

You'll see teh blue power supply caps. Add some film and foil bypass caps to each of the main filter caps. Will make a large improvement in the sound quality.

then get a tube pre amp and you should have a system with will sound significantly better.

best of luck
Johnss: Your suggestion seems "sound" to me (pun intended). I hear the other commenters deride the Adcom amp, and I appreciate their suggestions (hey, I asked, didn't I), but I think the critcism is largely unwarranted. I'm not an audiophile per se, but I'm a fairly educated fellow and I've listened to A LOT of systems in my time. The set-up I have now is among the best I've heard. The combination of the Arcam HDCD (I have not played standard 14 bit CDs in it yet) and the KEF speakers create an open and distinctive soundstage. The mids are a bit bright or "harsh", but they are crystal clear, and the stereo separation and clarity is shocking. Voice reproduction from the 6-1/2" Uni-Q drivers is uncanny. The reason I went with the 200 wpc Adcom, however, is that I could get relatively little bass response from the KEFs. The Adcom took care of that. It is true that I have not listened to any quality tube gear. From the comments it seems tube gear is genuinely superior. Since I am generally happy with my equipment, though, I would like to try the tube preamp suggestion (I am also a little "cheap"). When you say "add some film and foil bypass caps" I know you are referring to capacitors, but I have no idea how to add them to the circuit board. I'm sure you solder them in somehow, but I think your suggestion may be over my head. Do you think the average tecnician from a local eletronics repair shop would likely know how to make these improvements?? Also, If I am going to try the tube preamp, is there a recommendation? Will I also need a tube tuner?? Thanks all!!
Hi, I would say that the power amp is the weak point. I am using an old Adcom GFP 1-A preamp with my custom tube power amplifiers.. Dont let the rich guys talk you down.. The Adcom is a decent preamp. I have a Conrad Johnson preamp and the Adcom is better, hands down. If you are interested in a nice stereo tube power amp let me know, I can custom build to order. It will definitely change the way you listen. What is the efficiency of you speakers?
