Because these amps can not be bridged into mono, I use only one channel of each amp. For example, connect the left RCA to the left input and connect the left speaker terminals to the left speaker. Then do the same for the right channel. This does not increase the rated power, but it does do a couple of good things.
- It lets you mount the amplifier closer to the speaker if you wish, using shorter speaker wires.
- It provides better channel separation so that fluctuations on one channel do not steal available power from the other channel. This keeps the power supply from sagging and essentially increases headroom.
I would try one amp first and use it normally to see if you like the sound quality. These amplifiers are intended for near-field or mid-field speakers in fairly close listening situations. If you have inefficient speakers and you want to fill a large room with sound, these are not the amps you're looking for.
In my small studio I sit six feet away from my monitors, they are 4 ohm, I am using XLR inputs, and I do not like to play really loud, so these little amps work for me.
Something to note, the XLR outputs on my DAC put out higher signal level than RCA outputs. This is typical of most true XLR outputs, more so on mine, which go a bit higher when set for that on the DAC. This might impact how loud you can play these depending on your DAC using RCA.
If your speakers are very efficient, say 90 db and above, you could do some serious loud with these. Mine are rated at 84 db, so they will not fill a big room with loud sound, close listening at satisfyingly punchy levels in a smaller room. ( using XLR outputs from my DAC).
So, try one first, see if you like it, add another if you want to experiment with audiophile obsessiveness.
I hope this helps.
I wanted to use the SMSL with two FULL-size 4 ohm Dali Opticon 6 tower speakers - sensitivity is 89. I previously had a Marantz NR1607, pushing 50w x2 to each speaker (biamp). I want concert loud, I want audiophile clear, and I want it for $160. Who doesn’t?
I just got the amp in the mail, and naturally, hooked it up to blare some Post Malone - Psycho and Wow to test this amp’s guts. I also tried some Trevor Hall for quality. I’m impressed, but there are some caveats, and I won’t be keeping it.
The amp will easily push these towers loud enough that any pet you have in the room will get up and leave. Your wife will hear the bass from the garage. The bass is not lacking, as others have said. This review is 100% flat EQ, and RCA / Bluetooth. I tried both, and am not able to discern a difference, telling me that the amplifier circuitry, and not the DAC is cause the loss in quality.
The amp sounds perfectly clear at volumes that you could reasonably play with guests in your house, and still hold a reasonable conversation. The SQ is great at this volume. Not as crisp as the Marantz, in a way that I would describe as suddenly understanding the lyrics to a song you’ve heard 1,000 times because your system is so clear. The DALIs do this with other amps, the SMSL doesn’t.
Ok, so it’s time for a house party. Some a-hole turns it up to max volume. What’s going to happen? You’re going to damage your speakers due to amplifier distortion. It does get loud enough to have to yell over and will shake your house. Unfortunately, if you have it loud enough to yell over, you’ll get some distortion / popping at max volume. Again, this ONLY applies to listening levels where you yell “WHAT??” after each person speaks. The Marantz could drive these DALIs to concert-level volumes with absolutely no distortion, ever.
In conclusion, this is a BADA** amp for your bedroom, garage, computer speakers, etc; but it will not gain a spot in my living room, where I like to hear new nuances in old songs. It just doesn’t provide that level of quality. What am I going to do? I’m going to head to Goodwill, pick up a 10 year-old Denon that weighs 35 lbs for $29, and buy a $50 Bluetooth adapter. That will provide the SQ I’m looking for.
In short: If the SMSL has what you want, I say go for it. It’s producing no heat. It gets loud and sounds and looks good. Expect the sound quality to be on-par with other $160 receivers, such as Pioneer or Insignia. If that’s what you’re expecting, you’ll be impressed :)
