Will the Yamaha A-S501 be enough juice for the Wharfedale Aura 4?

[eternalmetal]

The current system is as follows:
Integrated amp - Yamaha A-S501
Speakers - Klipsch RP-8000F II
CD Player - Marantz CD-50
Cassette - Aiwa F770/Sony TC-KE400S
Turntable - Technics SL-1200 GR2 w/ Sumiko Songbird Low-MC cartridge
Phono Preamp - Schiit Mani (OG), still waiting on my Darlington Labs MP8B to ship
DAC (for PC streaming) - Schiit Bifrost
Room: 11x17 lightly treated. Carpet, drapes, cheap foam at first reflection for the attenuation of highs
Budget: ~4000 USD

I enjoy my system immensely at the moment, but the fatiguing harshness of the Klipsch speakers is urging me to upgrade. I primarily listen to brutal death metal, but I branch out among most subgenres of metal (old and new) with poor and good production values, electronic/ambient, some jazz, blues, and classical. The Klipsch definitely capture the in your face live music vibe, but I really want more refinement in presentation, soundstage, and a less sibilant/harsh high end. My initial plan was to upgrade the sources (garbage in garbage out), then my phono pre-amp since the Schiit Mani OG is not doing the MC cart justice, then replace the Yamaha with a Purifi/Hypex amp and shop around for pre-amps before replacing the speakers. But ive decided to go the speaker route first since I want to use the Klipsch for my TV setup downstairs.

So I used Google AI assistance (sue me) for some advice on speakers since speaker choice can be absolutely overwhelming. I was presented with a few options, but in the end based on specs, other user input, and my music preferences, I have the Wharfedale Aura 4 in my crosshairs. Google AI says that my Yamaha will run these speakers, but to be wary at higher volumes since the minimum impedance is 3.1 ohms and the Yamaha is really only rated down to 4 ohm. I do plan on eventually upgrading my amp, but due to budget constraints I wouldn't be able to do it at the same time. Id rather not look for a compromise speaker to accommodate the Yamaha since it is not really a device to build a system around, but this is where I am at the moment. I was also considering the KEF R7 Meta, but they have a similar minimum impedance of 3.2 ohm. Also suggested was the Mofi Sourcepoint 888 which do not have this problem, but they are heavy AF and may not be resolving enough for my music preferences.

So is the Yamaha capable of temporarily handling the power duties for the Aura 4? Any advice either way?

The Yamaha will be fine unless you get close maxxing it out. It may shutdown from over-current but you'll be deaf by that point, or hearing distortion.
You might look at other amps with more power though (so more current before they shutdown or distort), and budget notwithstanding, Purifi & Hypex -based units have good watt per coin ratios. Don't discount a streamer/DAC unit too - Wiims are popular (amps too).

 

[eternalmetal]

So I likely wont do any damage to the speaker? I would definitely turn it down if the music starts to distort, but I do like to play loud.

As for after I get the speakers, I will definitely be looking at amp and preamp combos. Haven't shopped out anything yet though since im focused on speakers now.

Have you tried turning down the treble?

You can damage any speaker if you pump more watts into it than it can handle, from a meaty amp. The speaker will usually get noticeably distorted before this point, but it's fun to blow out a cone or melt a voice coil if you've never done it. It's simple battery/bulb stuff.People are often surprised at how loud most speakers are at say, 50W at a typical listening distance at home.

Amps can also be pushed into noticeable distortion if they are not very powerful and you are driving speakers that have high power handling very loudly - or if the speakers have lower impedance (the amp will deliver more current, hence they'll be louder).

You may want to do a bit more searching and reading on this site to get a fuller picture!

This is why I am asking. Based on the ratings of my equipment what should I expect?

Your amp is on the lower end for power, your speakers are on the higher end for efficiency. The Wharfdales are on the lower end for efficiency, meaning they need more power to reach the same spl loudness as your current speakers and amp. Turning up your current amp to match the same spl could damage the new speakers if you drive it into clipping. So look for a beefiier amp, or keep your current speakers.

Also reevaluate the "fatiguing harshness" of your current speakers. Is this something you read on the Internet about Klipsch speakers? That widespread folklore has been addressed for a while with Klipsch new horn design.

Or maybe brutal death metal at loud volumes will sound harsh on any setup because it's supposed to?

A wise decision in my opinion. Chosing new speakers is easily the hardest part of upgrading, but that's where the upgraded sound is to be had.

I think you will be fine with the A-S501 initially. But might want to have it on the list to upgrade next.

I would recommend you do some reading on Amir's speaker reviews. You need a speaker that rolls off nicely on the top end. Many (most?) speakers have the tweeter too hot. If you get a speaker that rolls off fairly quickly after 10 khz. The louder (as you like to listen at) you turn up the speakers the more the hot tweeters really hurt your ears and fatigue the listener quickly. So, I would recommend finding a speaker that Amir has reviewed and recommends with the most roll off you can find. Most speakers don't roll off all that much so just find the most you can. You will notice NONE of this has anything to do with your amp or other equipment. Good Luck and let us know what you get and what you think about it.

At first glance, the pairing looks like a mismatch but, as you say, it would be temporary. I'm a little more concerned about your speaker choice. Quite large floor standers for the room. My suggestion is always to give speakers a listen before making a decision so I hope you're using a free trial to demo the speakers. Given the size of your room, you may not need too much power to get the volume where you like it. I hope you have enough room to position the speakers optimally. It took me demoing several different speakers before I finally settled on the ones I have now. Don't be hesitant to return the speakers if they don't perform to your satisfaction.

I have Wharfedale Linton 85th, and they dip to 3.5, so not quite as low as the Aura, but similar sensitivity and recommended amp power. I'm currently running them with a Denon x4500h av receiver, which is 125w per channel into 8 ohm, and I've had no issues with playing very loud for prolonged periods, so I doubt you'll have problems with the Yamaha. However if you want to upgrade from a power perspective, I've run the Linton's with fosi v3 mono, 3e Audio A7 and the Sabaj A20a (2022), and they've all done the job. If I was buying again now I'd probably go with the A7, just given it's less clutter than the fosi and more functional that the Sabaj.

In respect of sibilance you should probably look into peq first. I struggle around the 4khz range, so knocking off a few db at 4khz has done wonders for my enjoyment. Wiim amp ultra could be a good option for all-in-one solution, with peq / room correction, 200w per channel at 4ohm and it's capable of handling 2-ohm loads.

I find brutal death metal just not worth listening to so may not understand what you're doing to yourself at what volume Maybe a sub? A more powerful amp? Those Klipsch are decently sensitive but the 501 is only a modest amp in terms of power otoh. How far away do you sit from speakers? Just how loud (spl) at your listening position do you need? Try using something like this to help? http://www.hometheaterengineering.com/splcalculator.html

Think about something like the WiiM Amp Pro.
It has some really nice features, including PEQ for room correction and built-in streaming services.
Unfortunately, it only has one RCA input, so if you want to use multiple source devices, you’d need an additional cheap RCA switcher box.

I suspect the sound that the OP needs - "more refinement in presentation, soundstage, and a less sibilant/harsh high end" - is largely baked into many of the recordings being played, more than the kit being used. A lot of *.metal is notoriously poorly recorded.

Sure, the biggest change usually comes from speakers, but the room is important too; some rooms full of hard surfaces can 'jangle' especially at volume.

Look up Glenn Fricker (SpectreSound) on YouTube who is reasonably convincing as a recording engineer specializing in metal, for a bit of background "entertainment".
