ARC users please


I have been trying many different budget preamps just for the fun of it. I have stumbled upon a Audio Research SP7.
This thing sounds amazing. Any preamp under $1000.00 that I put in my system doesn't come close to the sound of the SP7.
Everything else I try sounds like it is in mono compared to the SP7. I don't know how to describe the difference. The sound is more alive and every instrument is in place.
My question, is this a signiture ARC sound ?
I have read good and bad reviews of the LS3. So I am not sure if I need to look for a certain model to upgrade to, but still keep that synergy in my system that I have now.
Thanks, Scott

Scotthk,

I had an ARC SP9MK2 which is a Hybrid using both tubes and SS and I have the Vandersteen 2CE sigs. I bought some good Amperex tubes and the unit sounded excellent. The phono stage had quite a bit of gain and that was the best phono section that I have heard to date. I have since sold it and bought a Tube Audio Design by Bizzy bee which also has a phono section. While the phono doesn't seem to sound as good as the ARC, the line stage is outstanding, better than the ARC with the Amperex tubes. You can get one new for about $700. I have no reason to change...

I had the Rogue 99 Magnum for a while. I didn't like it really. The sonics weren't too bad. Not what I was looking for. But, I just didn't like the 99 much at all.
I owned the SP-5 had it modified to an SP-7. It was as they others have said not the same sounding as the SP-8 which my best friend had and we constantly compared. I then tried the SP-9 for awhile(okay 3 weeks) and traded up to the SP-14, which I really liked when I was usung a phono stage!

I'm now using an LS 25 MkII which I've really been happy with.IMHO the older designs are more"romantic" sounding but in all honesty to me they did need to be upgraded in some way to be great across the whole frequency range. Usually excelled in the Midrange and upper midrange but did not have the tight fast low end and extended highs that the newer units have. But then again they aren't perfect either;)
Okay, that is my point. SP-5,7,8,9 and 14 and then a 25.
How do you keep track of the good ones from the bad ones?
