They run very well. I am please with it. I can not turn the volume know past the 1/3 mark without hurting my ears. Not bad for $75.00. With the $130 speakers, it is a very good system. I do not think you can get a better system for $205.

Would agree with this. I’m getting the SU-8 to output into my THX 789 and the SA-98e.
I cannot believe it…got on second amazon sale. It seems I have bad speaker. One speaker is muddy sounding, less volume. I have ticket into micca. Hopefully it can be resolved without waiting a month for the new amazon listing…
yes, i tried different cables, amp, and reversing polarity. and the simple switch speaker test.
I am in almost the exact same situation. I got in on the recent restock at Amazon and finally got to try them on my desktop for the last two days. Very muddy out of one speaker. I swapped out cables, used a different amp, etc, its definitely the speaker. Sending back today.
micca support said there was loose connection in speaker and is sending back to me. hopefully this isn’t sign of widespread QC issues.
Topping PA-3 or Emotiva BasX A-100? to drive the RB4s?
So been using the SA-98e with RCA input from SU-8. Definitely not very clean, there’s an audible noise floor when you put your ears close enough it. But i can’t think of other power amplifiers powerful enough and cheap enough to power these. Perhaps Emotiva A-150.

A bit large for a desktop set up, those are amazing amps though. I need something like the A-100 or the SA-98e in terms of size. But I could just be wanting to have my cake and eat it too
I hope not. The mesh cover seems to be shoddily made too
I had these in my game room hooked up to the BasX A-100 and it had more than enough juice to make these sound really good. But I was getting a weird reflection and am limited in my placement so I decided to move these to my desk and replace my old Bose Companion speakers. I have the Topping D30/A30 stack and thought I’d round out the stack with the PA-3. The PA-3 can power these speakers but not as effortlessly as the Emotiva. Even near field I am cranking the volume pot anywhere to between 1 and 3. I do not listen to my music loud so that tells you a little bit. The RB-42 has impressive bass for such a small speaker and with the PA-3 I found the bass response to be less than with the Emotiva.
I’ve driven the RB-42’s with a PS Audio Sprout 100, Emotiva BasX A-100, and the Topping PA-3. That happens to be the order of preference as well. It sounds decent through the PA-3 but I’d buy the Emotiva if you can. It sounds a lot better.
I’m going to revise my earlier statement. Again it was a placement issue. After reassessing my setup, and moving the RB42’s down to the desktop (they had been horizontal on a shelf) I think the PA3 is actually pretty adequate. The Emotiva still sounds better but for near field the RB42’s sound pretty darn good through the PA3.
These speakers do seem to be sensitive to placement, but the PA3 works great for near field. If you’re going to try to use these to fill a room I’d recommend something more robust. This’ll do it, but only just and when you’re using a Class D amp at, or nearing, it’s limits you introduce distortion. Once I took these down and put them on the desktop (angled up on the Micca foam isolation stands designed for the MB42’s) they really sounded much better.
These arrived today with a Topping MX3, sounds good to me. 10/10 would buy again.

they’re back guys, now $20 more 
I’m pretty set on getting these as my entry into proper speakers and I’ve settled on the SMSL SA-98e for the amp. However I need to know if I can use my Micca origin+ as a pre-amp and if I may have any issues with this setup, If anyone could offer some help with this i’d really appreciate it.
If anyone has any alternatives for the amp however, feel free to make a suggestion.
Thank you.
This is out of stock,
