i have kept the sansui 907 for 3 months now .
My speakers as i mention are the klipsch RF3s .
though this amp performs great but i expected too much from this amp.the sound isnt jaw droppingly great . It could well be the speakers and amp matching ....
I have heard of JBLs L112s to be a better match for this amp breed.
My klipsch just did a whole lot better on tubes .......
What to do now .....
Tough decision.
It may be speakers and amp matching as you say. From what I've read, that just may be the case!
The 'alphas' are 'audiophile sounding' (more like a Ferrari), not like the AU-717 (07s) and some of the earlier amps (more like a Shelby Cobra muscle machine). The alphas are a slightly different sound, a more refined sound, not as deeply felt, but still plenty deep, but less flavored. Not as much of a live concert sound. But the alphas still have the depth of sound, just not as deep and lively, by that I mean like 'alive'. The AU-717 just sounded alive. Yeah, to your chest and soul. More
'PUNCHY' I guess would be a better word.
Same, but different. More refined 07 circuitry I believe. The earlier Sansuis are like more raw, the alphas more refined. It just may be very well an amp to speaker problem.
Again, I've hear the 9500s a long time ago but can't really remember what the 9500s sounded like other than they sounded really good and nice.
I've never heard a Sansui MOS. I'd love to hear one someday. The MOS should even be better in the alphas.
I know, It's gotta sound right, if not, it sounds wrong and drive you nuts!! LOL. And it's hard to live and deal with that, cause your listening to it!! Yeah.
In any event, I wouldn't be in a big hurry to sell the AU-a907i MOS Limited. It's a really great amp. And it's a MOS.
Anyway, which ever way you decide to go...Good luck!
The Sansui 907 is super hard to come by, it may be that your speakers are not mating well. For reference, I have newer Sansui amps that mate better w/ certain speakers and don't sound good on the 9500, I have other speakers that sound best w/ the 9500. I would not be in a hurry to sell the 907 until you're thoroughly vetted it with different speakers. If it sounds audiophile-ish to you, try it through some Snells or Polks, I find klipsch to be very analytical. In fact, get some vintage AR's and run the 907 through them. IMO the whole thing is about synergy.
I'm a bass player FYI so to me the lows and low mids of the 9500 are not only heard but felt, and not in the boom boom way, they're just large.
Totally agree.
Also, just food for thought: Do your Klispch speakers have AlNiCo magnets on the woofers and mids? AlNiCos really warm up sound, and for me, music CDs too. Analog LPs sound simply wonderful. Do you use a sub woofer? I don't like them all that much myself, I prefer to let the speaker units 'do the work', but that may be a solution.
One thing for sure...your amps got 'MOS' so that should really make a noticable difference in sound for the better. If not, it's gotta be an amp to speakers compatibility issue.
Yes, the older Sansuis had a 'large - deeper' base sound that was
' f e l t ', yes. EPI is exactly right, that's what I was trying to say.
: IMO the whole thing is about synergy.
Agreed: I've never personally had a 'synergy' issue, ever, but it may be just that.
From what I've read, and understand, in my Sansui research...Sansui used JBLs basically for their matching equipment to speakers, and their own speakers of course. I know Hasimoto (who has the rights to build new Sansui transformers) uses JBLs for demonstrating their new 'Sansui' designed transformers and amps for demonstration in shows. Seen the photos on their website.
Also...I've always liked Klispch speakers. A friend of mine had a big pair, can't remember the model number, old ones, like pre-1984, he bought them new, and they were awesome! Just shook the house.
They sounded quite amazing really. But he wasn't running a Sansui amp. Can't remember what amp he had...I was just focused on the speakers!! haha. He did have big horn tweets. They sounded awesome. Really in your face though. Not laid back, that's for sure. Maybe it was because of the horn tweets. Sounded GREAT! They did just 'blow-you-away', like you were 'on stage'.
In my older years now, I'm a bit more into a laid back sound. And I have neighbors!! haha. Those Klispch would just crank the neighborhood!!!! Nice speakers.
