    Well there is no KIT . Only hand assembled amplifiers and the rest.
    As for the BA 5000 the biggest power amp SANSUI ever made , it was not the only one. B2301 B2302 G33000 had the same power rank. They all sounded a bit different compared to BA 5000, actually better. The one and only B2301 , B2301L , B2302 actually sounded a lot better than the good old BA 5000.

    Personally... I'd rather have the Sansui AU-a907i MOS Limited.

    Absolutely.

    I never liked the Krell gear too much. When it was my time to buy a big amp that doubles down (power with halving of impedance), I went for another brand amp (pictured in my avatar at time of writing), which to me sounded much sweeter. Then I sold that amp to get back to Sansui. Go with your heart/ears!

    Or maybe you just didn't like the sound of the Sansui on your speakers. It does happen.

    If it's as good as it is unattractive, then that is the worlds best amp.

    I'm sure it's sonic-ally very nice.

    An amazing piece of kit, by the man from Krell.

    It should amaze at $56,000.00 dollars.

    That thing is the Krell Momentum, and it is an integrated amp.

    The Krell KAV-150a seems to sell today for 1,500 bucks on a low-ball average, but that is without a pre-amp.
    It was first made in 1999(?)...18 years ago.

    It seem here are a lot of considerations that make Sansui more comparable than you assert.

    But its fun to promote one's preference to doubters.

    Here is a review

    Well, the volume control alone costs 7500 dollars. The whole chassis is solid copper and machined from copper. It is also hand built, soldered and tested. So, yeah, that all costs.

    as an owner of a kav 250 I would like to say that there's no way around a krell amp having an objectively better ability to drive speakers than a sansui.

    I've owned g7000, and 9900z alongside other sought after Japanese power amps from that era- onkyo m504, denon poa 2400 etc. These aren't exactly the same as OP's amp but they were all crushed by the SQ that the krell provided

    Do some research, even though the kav series aren't the behemoth class A amps the ksa were, they have significant praise and are an excellent value on the 2nd hand market.

    I have always been on a quest for high end sound at a reasonable price and the krell truly delivers. I plan on getting another and running them as 1kw monos

    If you have hard speakers to drive krell will always win out, otherwise its on your ears to decide which house sound you like

    Nah, that is what a Sansui wants to be when it grows up. :)

    A pair of 8inch diy audax drivers and alcone tweeters in a cabinet that weighs 25kilos. Sooper sized bookshelf speakers .
    . 92db .and 70 watts, almost home made .
    But very pleasing .
    I sold my klipsch RF3s 3 yrs ago when i demoed these next to em.

    Bringing this one back, now with more info.

    Did you get a chance to audition the Krell vs. the Sansui? As to the drivability of the Mezzas, shouldn't be a problem they do sensitivity: 92.5dB/2.83V/1m. Nominal impedance: 4 ohms (EN 60065). Minimum impedance: 3.8 ohms. Recommended power is 50-250. One thing about speakers today is they can handle more power than in the past, generally.

    I am with you on the glory of Sansui 70s gear. Just want to point out that I've finally dipped my toes into some of the better 90s Sansui gear and IMO they got back to the 70s sound at the end. In fact at comparable power levels the new stuff is almost indistinguishable from my AU-777A in double blind.

    Of course the big Krells will drive almost anything which can't be said of the Sansui units. With more regular loads I think many will be surprised with how similar well designed (and sorry, but that does include many Sansui) amps sound in double blind. Even with an amp selector box instantly switching between the amp you will find it hard in many cases.

    The Sansui circuit designs were certainly within economic limitations which limits performance in extreme, but were not limited in design quality.Actually Sansui was probably a leader in circuit design. Even to this day their ideas are getting reused and reinvented from diamond diff to super-feedforward (even saw the later used in an NSOM (near-field scanning optical microscope) research paper recently). Outside of extreme power/speaker demand situations the differences are not as big as many think. Double-blind tests on my end have 'been there and done that'. I've compared the Sansui gear to various big amps including Krell, ME (defunct Australian brand), ML, McIntosh, etc. And I measure on the bench too... once you get past the era of strong voicing of amps (which seems to last up to some point in early 80s), there isn't much difference between well designed amps, under usual operation. As Nelson Pass says, good amps mostly behave the same under normal conditions; it's how they misbehave that is where the differences are.

    I don't post too much about all of that (Sansui vs the big boys) because I think one has to really experience it to believe it. Without that experience, you are unlikely to convince either party. But I do talk a lot about Sansui vs Sansui, because that's what people are here in this forum for :).

    While Botrytis and I have some different points of view I like to think we could debate this all over a cold beer and have a nice chat. One thing Botrytis is right about IMO is the need for double bind testing. I basically don't listen to anything on this forum anymore about amp flavour and comparisons unless the poster mentions double blind AND amp selector box. All of my amp comparison tests are done blind and with amp selector box. Without double blind I sometimes get it right, if I'm using the amp selector box going between the amp instantly, but without the selector and double blind I often get it wildly wrong. E.g. Recently I swore my newly acquired alpha-907limited was bright and lacking bass in comparison to a smaller underdog. I thought that for a week until I inserted double-blind and amp box, and there was not much in it at all. I was surprised myself when I realized how much I let my underdog champion mentality get in the way. I've been doing amp comparisons since the early 90s and I thought I could let my experience bypass the need for the proper amp comparison procedure for a week as I moved my setup around. I was wrong.

    As I wrote in an earlier post, I have had various big amps and have come full circle back to smaller vintage stuff. Each to their own (depending on your speaker load and volume requirements :) ).
