Yes, the SET 120 has identical audio circuits as the SET 400.

It just has lower power supply voltage and lower power to fit in the smaller chassis and require lower voltage part ratings.

The sound is identical. You would hear no difference at all with efficent speakers.

You can order directly from our web site.  Build time for you is 2 - 3 weeks with Thanksgiving taking a long weekend from our schedule and many other orders ahead of you.

It won’t be like waiting for a Tesla though.

Well my situation has changed since the last time I posted here. I still have the ZU's so the SET 120 would be an excellent match for them but I now have a pair of Magnepan LRS's which I am told love power and current. So I might be saving some more pennies for the 400.

Yes, I think the 400 is the clear choice between the two now that the LRS has entered the picture.

YEP! It's at the top of my list for end game amplifiers.

So I am trying to get a higher quality amp into my system for my LRS's sooner than later and was wondering how the SET 120 would do, "for now?"
Once I do get the SET 400, I plan on moving the SET 120 to the home theater room for a pair of VERY efficient ZU Audio Omens.

I just received my LRS's a week ago and have been using a Belles Model 1 (100 wpc at 8 ohms, no idea about 4!) and a Sansui AU-5900 (45 at 4 and 8 ohms) and both of them have no problem at all at moderate (concrete apartment cave levels).

If you get the 120, please post! I'm looking at it as well.

After having the SET 400 and Alta Audio Titanium Hestia's for a few weeks I can truly say they are a synergistic match. The sound fills a large living area with ease and authority. The imaging is uncanny and bass is full with out ever getting in the way. I have tried the 400R with the Alta's and there are more things that are similar than different. The 400R has a little deeper soundstage with a slightly liquid sound compared to the SET 400. The Set 400 is more forward with the air of the recording well into the room with you. I could live with either and be happy for a long time. For speakers that need some balancing in frequency response, either because they are built like that or room interactions, I would go with the 400R as tube rolling allows you to dial in your sound. However, the Hestia's are so well balanced that the SET 400 is perfect for them. The SET amp definitely has a unique sound that should be heard by any of you that think a fully transistor amp can't convey the emotion of the music. A $2000 amp running $32000 speakers, blasphemy, I know, but I don't think I could do much better for 5 times the price. The guy I bought the Hestia's from ran them on the SET 600 monoblocs and said they sounded better than the SET 400. I might consider trading up one day but I have plenty of power now and am enjoying the combination

I can build you a mono pair of Vision SET 400 amps, each with a single XLR input. The amps will then be true balanced designs with about 300 watts each output. 

Now what is your excuse? 🤨

Frank
Is the same doable for the Vision SET 120?

The amp I am using right now is putting out about 125 watts per channel into 4ohms. And like you, at moderate volumes, it has no problems powering the Maggie's but when I want to really get dynamic, 125 watts is not close to enough. More headroom with theses Maggie's is MUCH needed!

I think my definition of "moderate" is different than everyone else's!

I think you need a SET 400 to get the best out of your speakers.

Matthew, as I am a long time Maggie owner, I can tell you that your LRS's will sound better with more power.  The music becomes more dynamic and fuller. Bass will also hit harder. I run 500 wpc with my 1.6's and 250 wpc with my original MMG's.

The SET 400 would make your Maggies sing beautiful music.

Frank, can you do this with the SET 120 as well?

Mono versions of SET 120 amps?

Can't be done with the current generation of small chassis.  There just is not enough internal heat sink to support bridged mono very high power into 4 ohm or 2 ohm loads.

The Set 120 is great in stereo mode into normal 8 ohm or 4 ohm loads, but bridge mode triples the power and cuts the speaker load in half and very high power into 2 ohms is a bit much for the heat sinks.
