audio research sp-10


hi..i'm fairly new to tubes. i have an AR sp-10 pre, AR d-125 amp, vandersteen 2ci speakers, and a shanling t-100 cd player. running the cd player on the tube output of the shanling. my music tastes run the gamut from synthpop/techno...to sarah mclachlin, and josh groban. the system seems just a tad bright to me, which it seems it shouldn't with all the tubes i'm using. i've put the sp-10 on "high gain" which seems to help...is it "bad" to use the high gain on a regular basis? also..my speakers are biwired..but with no name wires..any suggestions for compatable speaker wires and or interconnects (using legend interconnects right now) or any other suggestions would be appreciated. thanks in advance :)

I currently own an SP10 as my main preamp. I disagree with the posts above, it has a great line stage. I wont use it for CD's because I dont want to waste the tubes on CD listening. Quality tubes are not that easy to find anymore. The SP10 is a tube microscope. When I picked up mine, it had sovteks and it was too bright for me. I immediately changed them out. The best tube I have come across in the SP10 is the Siemens 7308. They are fantastic in the 10. The tubes you put in the SP10, good or bad, form the personality for the sound quality. There is also a thread on tubes for the SP10 in audio asylum by "bambi" that is very informative. I have owned the SP11, SP8, SP6B SP3A1, Klyne SK2A, Klyne SK5A, Spectral DMC10 and many others. No matter what, for me, I always preferred the sound of the SP10. Anyways, there are many opinions, use your own ears. If you can get a variety of tubes to try (not so easy these days and very $$$$$), you will discover why this preamp is considered one of the best by many.
Turn it off at the end of each day when you are thru listening. The SP10 has a very gentle warm up phase and the tubes don't suffer much from turn on trauma.

Linnlp12, you won't get much argument from me, except we differ on tube preference a tad. I've been using mine for over 20 years - warts and all, its still my favorite pre-amp.
linnlp...thank you so much for your imput...when i can afford the $ i will try those tubes as well as the ones that newbee reccomended..this is really fun with the help of those of you with so much more experience..

newbee..will do..thanks again:)
hi..its me again...do any of you have any suggestions for how i can make 6" high speaker stands for my vandersteen 2ci's until i can find the sound anchor ones used? thanks:)
Hey Hey Synthgirl,

If you have not had much success to find tubes, perhaps you can call Michael Elliot, the designer of Counterpoint gear. Go to www.altavistaaudio.com and click on "Replacement Tubes" on the left side of the page. Then scroll down to the 6DJ8 links in the products line. He has grouped tubes with different noise/microphonic levels. Just give him a call as he is very helpful.

Also, I respect LinnLP12's viewpoint that he likes the SP-10, but all the units he compared it to are those at the same time or long before the SP-10. I too heard the SP-8 and Spectral DMC-10 along with the Klyne and Krell PAM3 at that time and for me the SP-10 was hands down the winner. But that was then! Line stages have come a long long way since then (1984). Your focus needs to be on a product that serves CD playback well. Wish you lived here in Minneapolis as I'd be happy to invite you to hear what I am talking about.

Anyway, give Mr. Elliot a call as I think he could help you here.
