Amp for SF Sonetto ii

I am going to be purchasing these speakers after a good audition and I am worried about driving them being 4 ohms. My original plan was a denon 3700h or similar but now thinking I might need something better for 4 ohm speakers. Just 2 channel for the time being. In an open floor plan living room kitchen. So any AVR/ power amp or integrated would work. Would be part of TV movie gaming system. Any suggestions? New or used.

Great Speakers

These are good speakers../ particularly for audio. I have had a number of different Sonus Faber over the years, now Amati Traditional. I really haven’t had a problem driving them. They are great speakers... but you know it is best to match all speakers in a home theater environment? So it would be best to get all identical speakers... the center too. There are lots of high power av amps available. You can check generally if an amp can drive them from the specs on the amp. If the wattage nearly double from 16 -> 8->4ohms then it is capable of driving the speakers well. High current is better... this is a measure of the amps ability to produce current at low impedance.

If you put together a home theater around SF speakers it is likely to sound fantastic if being feed good and adequate power. Will be good for miscible as well as av. Av is much easier than two channel... since you are distracted by the video.

Have a listen, first!

The mere ability to drive 4-Ohm nominal load speakers with an 87dB sensitivity and the ability to squeeze everything out of them they are designed to deliver sonically are 2 very different issues. At 105 WATTS into 2 channels at 8-ohms with a THD of 0.08% and 135 WATTS into 2 channels at 6-ohms with a THD of 0.7% (couldn't find specs for 4-ohm output), it appears this Denon is capable of driving the Sonus Faber Sonetto II. However, my question would be how well? Go have a listen to both of these paired for a 2 channel demonstration/audition, if possible, preferably in a sound room as similar to yours acoustically, as possible, and then have the salesperson hook up the SF to something with a little more oomph in the power supply section (i.e. not more WATTS, per se, but more robust power supply). Your ears may find the SF perform significantly better with an amplification source that can deliver more current when they need it. Just sayin'.

I do own these speakers and I

I do own these speakers and I drive them with Pathos Classic One MKIII. The pathos is rated at 70W at 8ohm and 140w at 4ohm.

Yup!

I'm not familiar with the Pathos Classic One MKIII, other than some quick lickety-split googling I just did. However, judging from it's hybrid design incorporating tubes and it's specs, it's easy to believe this is a good match for the SF II.

I recently auditioned a pair of Aerial Acoustics 6T with a McIntosh MC275 and McIntosh pre-amp (forget the model number) and a McIntosh MA5200. This was a direct A/B shoutout in the same shop, same room, same everything. The MAC MC275 is rated (probably conservatively) at 75 WATTS at 4, 8 and 16 Ohms and the MAC MA5200 (definitely conservatively) at 100 WATTS at 8 Ohms (more likely around 130 WATTS). The Aerial Acoustics 6T are a 4 Ohm nominal design with a 90 dB sensitivity rating. They are hellaciously beautiful speakers that sound heavenly! I would have bought them in a minute if I'd had an amplifier that could do them justice! Although they sounded really, really nice with the MAC MA5200, it was easy to hear they much preferred the current the MAC MC275 could feed them. You didn't have to listen long to figure that out. Five or ten seconds was all it took.

The pathos seems like it’s

The pathos seems like it’s similar to my current rogue Sphinx tube pre but with class d 100/200wpc. I plan to use this first but I need to connect it to tv through hdmi so I can control the volume through the tv (others in the apartment). I’m pretty much between the Nad m10 or the lyngdorf Tdai 1120 as they both offer hdmi, room correction, and dreaming built in.

Have a listen

Don't know much about AVR equipment and all that multi-channel audio visual stuff. I'm strictly a 2 channel music audio guy and not an expert at that by any means. That being said, I do have my MAC integrated connected to my TV (via optical) and don't mind using the amp's remote to control the sound at all. The only time I use the MAC for TV audio is for music shows like the Grammy's, Country Music Awards, Austin City Limits and programs like that. I've been addicted to this audiophile stuff for decades and have learned a few things along the way. The best advice anyone can give you is to go have a listen or two or three to the stuff you are interested in, under controlled conditions and, if possible, in direct A/B shout-outs. I know what my ears like and your ears will know what they like, as well. As the old saying goes: you don't have to know much about art; you just have to know what you like. If I had to make a purchase like this, blind (i.e. without critical listening sessions), with those Sonneto in mind, I would opt for an amplification source with as much power (i.e. watts AND high current capacity), lowest THD, lowest IMD and best SNR as I could afford or want to spend. Good Luck!

The problem is there are so few dealers and they don’t all carry the right brands to compare the right products. I had the chance to hear the nad with the Sonetto towers but not the lyngdorf or anything other options in my price range.

Totally Confused!

Sorry, but I'm totally confused. When you write: "I am going to be purchasing these speakers after a good audition..." does this mean you've already auditioned the Sonus Faber Sonnetto II, liked their sound and have decided to purchase them or are you thinking about purchasing them AFTER a "good audition"? Also, being "... pretty much between the Nad m10 or the lyngdorf Tdai 1120" and wanting "Just 2 channel for the time being" implies, to me, you are interested in getting good 2 channel music sound, for now. However, when you write: "Would be part of TV movie gaming system" in the future implies you may want to move in the direction of multi-channel sound in the future which, of course, would involve the purchase of additional speakers. Do I have that right? Is that where the Denon AVR-3700H figured into this picture for a time? This implies the budget would be around $3,000.00. Is that about right? Also, is your "rogue Sphinx tube pre" a pre-amplifier or integrated amplifier? How do you see the Rogue fitting into this picture, short term and/or long term?

Don't go for Pathos if your

Don't go for Pathos if your system is mainly for movies. It won't shake the windows and wake all your neighbors, but it will present the music in the most gentle warm and romantic way. Here is a link where stereophile's Sam reviewed the unit many years ago https://anyflip.com/ierm/qvce/basic. FYI this is not discounted model and its still in production

At that point I had auditioned and bought them. It’s 2 channel for the foreseeable future but a combo movie tv gaming music setup all in the living room. I have purchased the nad m10 and will use that for a while. I may add a power amp to the pre ours later to see if that helps
