I have a chance to buy a BA 5000 but the price is on the high side.
Just how good is the BA5000 sound wise?
Currently i am using the AU20000 for power and a recapped CA3000 as the pre in one system.
I know they are rare and collectible but is it worth it to give up the AU20000 for one?
That's the only way i could afford it is to give up the AU20000 and then ad cash.

Thank you!

If I could afford it that way, and if I had the chance, I would do it. Btw, the pre-amp section of the AU-20000 and the CA-3000 are pretty much the same.

You already have the pre in the CA-3000 so I would think the AU-20000 might be redundant (although I have 2)but it really boils down to what your speakers require... do you need 300wpc @ 8,4, and 2 ohms? My Infinity RSIIb do need at LEAST that.... you would have to pry my BA-5000 from my cold dead hands.

Perhaps i worded things wrong.
I already have a AU20000 and am aware that the AU20000 is a combination of the BA3000 and CA3000.
My CA3000 is recapped with Blackgates which i think sounds better which is why i am using it as a pre and not the AU20000.
I am considering letting the AU20000 go to afford the BA5000 but have never heard the BA5000.
Does the BA5000 sound better then the BA3000 (AU20000)?
My speakers are rated at 350wpc @6ohms.

one thing to consider is the ba5000 uses ouput transformers which the ba 3000 and au 20000 do not.i've never heard a ba 5000 but do love my ba 3000.the au 2000 is close to the ba3000/ca3000 but they have their differences.sice you have the ca3000 already and has been recapped i'd jump on the ba 5000.

...My BA 5K sounds Different than my BA2K , that's for sure - it sounds better , if you want my Opinion - just because it's ability to Push the deep frequencies in some very special way....:yes:

The 5K sounds a bit like a Tube-amp , anyway - you should keep your AU 20000 and enjoy both of them...:D

I was within a hair of pulling the trigger on a semi local ba5000 a couple weeks ago. Then I got to thinking why not go for the real McCoy. The 5000 is sansui's version of the mc2300. I opted for the 2300's 500wpc bigger brother for less than the 5000 which also was local. Never ever thought I'd say I was glad that I passed on a ba5000 but in this instance I sure am.

The BA-5000 flat out Rocks. Most internet pictures don't do this Amp justice. If at all possible I would figure a way to keep both. In the past I have had to give up something in order to free up $$$ for something else. Never sits well with me. But in the end justified I guess. I love my BA-5K all 108 lbs of It

Buy the BA-5000 if you have a chance.... they are expensive WHEN or if they ever come around but worth it. The amp section of the AU-20000 can't even compare to the BA-5000 to my ears and power wise. Sounds like your speakers would really shine with the extra power. The 2 problems with the McIntosh mc2300 are 1) Really ugly 2) NOT a Sansui.

Never sold the AU20000 yet, the $500.00 came in handy to deduct off the cost of the amp:)......
I paid some good coin for it!:scratch2:

Very Very pleased with the amp, it sounds great!

congratulations on scoring a BA-5000, that is one Sansui Amp I would gladly donate a Kidney for.

I am kicking myself for passing up a mint BA-5000 early last year. I had little knowledge of Sansui gear back then, I had first option on it but hesitated and went off to do some research on what a BA-5000 was. By the time I discovered what it was and called the seller back it was sold. The seller had no idea how valuable it was as it was inherited from a deceased estate. Was sold for $500 AU.

Oh the pain ...

I have 2 x BA-5000's and woudn't sell them for anything. I have owned all the other Definition Series amps, and to my ears anyway, they don't come close, particularly when you start driving them to insane levels. The BA-5000 is king of all sansui's. Let your ears decide i say, you will see I'm right

Yes it is definitely a very nice piece, very attractive looking amp!
Question, my speakers are 6ohm, the amp has posts for 8/4/2 ohm loads, i used the 4 ohm posts......or should i use the 8ohm?

Hey guys. I stumbled onto your discussion on the Ba5000, I have owned 3 of these fellas in my young life of 36yo. I still have one but I run and prefurr the mac 2300 hands down. The raw power from the mac just explodes when bass is passed from its vains. The sansui has a sexy look to it, but the mac stills has that( dont mess with me) way about it. I run a sansui au7900 as my pre amp because I am a die hard sansui fan and have been since I was in my young teens. I have owned pretty well all the sansui au and ba series at one time or another, and yes a au 20k. The ba5000 is a power house compaired to the output stage of the au20k. Im not a flat sound type of guy, I like bass and I like sizzle. The au 7900 has the best pre amp of all the sansui stuff. I have my ba just sitting for show in my set up. Its not hooked up, but i do love it so. Amazingly they sell for more then the mac but as for performance the mac has a sizzle that the ba cant meet. I posted a utube video lastnite if you wonna see the mac and sansui side by side. The video sound quality is really bad but its still fun to watch. Just search (sansui ba5000) on Utube. Cheers!

I remember the MC-2300 (introduced in 1971) quit well and the BA-5000 (introduced in 1975) looks like a Japanese copy to me. That doesn't mean it's not a swell amp, it looks even better then the McIntosh MC2300 (A black enamel MC-2500 (1980) looks great though).
How does it perform on tough loads like those old Infinity's (bigger models from the Quantum & RS Series), SoundLabs, Apogees and Acoustats from that era. I once connected a MC-2500 on my Acoustat 2 + 2 and it had a hard time to drive them properly at every output tap.
It's hands down the best looking Sansui amp (I sold Sansui gear when I worked as a student in a audio shop) and probably the best sounding one.
Congratulations on your beautiful buy!

I'll revive this old thread. I've lusted after the BA5000 for a while. I still have a few MC2300s and have used them (in general) as my primary amplification for almost 15 years now. In that time, many many other amplifiers have come and gone but they remain a constant. No complaints.

I find the comments here about the BA5000 interesting, piquing my curiosity that much more. I also think it an attractive amplifier, but the MC2300s are far from ugly! Some have commented the MC2300 is the superior amplifier, but the BA5000 must have something above and beyond the Mc aside from resale price . . . what is it?

They sound very good, and they're very rare. Together, that's enough.

They sound extremely nice and they are pretty rear.
No wonder Sansui used to call them the definition series.

Well since the actual amp that started this thread is now living happily with me in Nova Scotia,I must say the "Monster" is everything and more what encouraging people say.As it sits there with it's beautiful glowing green meters,you forget there lies a sleeping giant.This amp was a true revelation in my journey through years of stereo gear ,hits and misses.It sounds exquisite at lower volumes,as no one segment of the music spectrum gets extra pronouncement. What I became used to in other amps was the lack of bass at reduced volume,and until I had my BA5000,I thought this was normal. The BA5000 is true and representative of the whole musical spectrum as recorded,no tone control gadgetry or loudness button needed.You get "great" sound at watt 1. But once you let the reins loose,and ask for some real musical muscle the BA5000 simply sounds extraordinary! Not just louder(yes it is capable of serious freakin louder!of course)but it remains unruffled by demands for more,just huge,expanding soundscape,cleaner,clearer ,more detail becomes so defined it is intriguing to hear intricasies that were lost in the "loud" of previous amps at high volume. It was mentioned on this forum by a user who said he used suprisingly(..to me anyway)much of the wattage that the Monster offered on occasion.I could only think of a very isolated residence,with disco flavoured speaker/monitors and a hearing impaired end user.Well, I use "on occasion" as much of this amp as my speakers can safely handle,because the sound never degrades,distorts,compresses or anything unpleasant for that matter,it makes you want more.Just have to be careful that your speakers are stable,and your neighbours like music.And with all that glorious sound previously out of my reach in the past,with so many amp(integrated/power) configs,including various receivers of all sorts,this amp I CAN'T do without now.Using a AU20000 as my pre,and both were just freshened up(post that story soon)I see this amp,the Sansui BA5000,as the centrepiece of something that I looked for since I bought my first piece of stereo gear many years ago.Never to be sold.

...Hope , that someday You'll find one at a reasonable price - for sure BA5K is one of Sansui's Masterpieces - I am very Happy with my Set of CA2000/BA5000...:thmbsp:

What I love about the BA-5000's is the effortless power that they produce. Like a big block V8 as a comparison, they perform right through the range without weakness. They are over engineered, designed to be driven hard, but sound impeccable at the same time. The definition series brochures of the time, invited audiophiles to let there ears do the deciding. They knew they had something special.
They simply drive any speaker and bring the best out of them regardless of what they are and rated ohms, even as low as 1 ohm as with Apogee Scintillas for example. Today, big money on Krel and Meridian amps has to be spent to comfortably drive these low ohm, demanding speakers. The BA-5000 is close to 40 years old and the mere fact it can drive these loads even okay, is testimony to its design and construction.
As for me, I have 2 x BA-5000's, consecutive serial numbers off the production line, they are related so to speak. One amp runs two pairs of speakers being, JBL 150A's and 220 Oricons. The other runs a pair of AR TSW-910's. I have other speakers and used to switch around quite a bit, but this setup for me works well for me, so i leave it as it is. Both amps run through a CA-3000 preamp. These amps do this easy and I love the piece of mind I get when playing multiple sets of speakers at high levels, which would fry the outputs on just about everything else.
These amps were seriously built to kick the ass's of other manufacturers at the time of production and make a name for themselves, which is exactly what they did and hence, there high demand, price and status they have today nearly 40 years later.
Overall, I prefer them to the similar big Macs of the era, as i believe Sansui's sound is better overall and crisper. In 1975, Sansui were hell bent on improving and bettering the Macs at their own game. Yes they plagiarized a lot of their technology, output transformers, even looks in many ways, but they improved on the Mac's in just about everywhere IMO. The difference being the ability to drive torturing loads at high volumes and still sound superb, unlike most others when loaded in this way.
It is common knowledge that these amps were produced with a great deal of disregard for manufacturing costs, in fact initially they ran at a loss, as Sansui's goal, was to produce an amp of impeccable build quality and sound reproduction which would consequently create its own following from audiophiles around the world and follow on sales. Risky venture yes, but they were confident of their product. Sansui were also well known for understating performance and distortion specs, as they knew once comparisons were undertaken, their reputation would quickly build.
History tells us that they were successful in doing this as this amp along with the CA-3000 preamp have legend status amongst collectors worldwide and pull enormous interest and resale prices. Undoubtedly , this is set to continue.
That's my 2 bob worth, others may differ in opinion, but for me the Sansui BA-5000 is king of the Golden Era vintage amps. Those of you who are lucky enough to own these amps, will know exactly what I'm talking about hey??
