Actual bench test with a conservative THD limit at ASR was
This is per channel with both channels driven, so in many cases the available power is even more.
118watts @ 8ohms
183 into 4ohms and fully 2ohm stable.(really good)

With higher THD allowed for (1%THD, dynamic power) it reached 240watts into 4ohms.

This is what you want as generally speakers have lower impedances in the bass and midbass region and in that frequency range music and movies have a lot of energy.

Cheaper amps will not have this type of power ratio and will sound thinner and less powerful in the bass and midbass.
This is a very good amp, it can handle even hard to drive speakers(ones that dip down to 2ohms) and not loose very much dynamic range at all.

I've heard nothing but good things about this amps power ability.

The one downside for some use cases is that it has sub out but no bass management. Bass management is very important to allow the amp to remove the bass from the mains and divert it only to the subwoofer. This is a flaw in the design that can be worked with but really in 2024 this should absolutely have that feature. Some buyers should pass simply because it does not and so other options are better for their set-ups.

Wouldn't your AV receiver do bass management anyways when you have subwoofer attached to AV receiver sub out?

This is an integrated amp. It has a subwoofer line output for connecting an active sub but no way to 'high pass'/remove the low bass from the the L & R channels.The main channels will always get a full range signal. This is not great.
This is an integrated stereo amp. It is meant for 2.0 or 2.1 stereo setup. Most of the speakers (specially bigger ones) are designed for full range and the filters inside the speakers will attenuate lower frequenies anyways. If subwoofer is used with the 2.1 setup and the bass management can be done with the subwoofer (crossover frequency, phase control etc.). So, there is no issue here.

If I'm going to connect to to my PC should I opt for the 801 instead?

Why? You will be feeding what speakers in what size room?
Does your PC have optical or coax digital out or what signal are you going to pass from your PC?

i think the s801 version was just on sale recently. I guess this 701 has LESS power than the s801.

That reads like this amp is good for Full sized Towers (containing a bunch of speakers)... and possibly forgeting about a dedicated sub.

so, stereo audio listening.

EDIT: post 21 already clarified.



I do have a question.. if an AVR has zone1 and zone2...

Is it doable with proper cabling...

to make zone2 have this yamaha amp for 2.0 stereo music enjoyment for 2 full towers...

while zone1.... uses the same full tower speakers in place... plus a center channel, plus sub... NOT using the yamaha amp?

How much power into 8 ohms? How many channels?
It's enough to power your 8ohm speakers louder than you would ever normally listed to. People get caught up in the dick measuring contest that is how many watts their amp can put out, all while not realizing that at normal listening volumes they are using like 10-20watts max.

Super tempting.

I was looking at the 701 or the 801 to replace my aventage a-740. (I no longer use the HT parts of the 740, I am just using it for 2 channel stereo music- in Pure Direct mode the 740 doesn't output a sub only channel)

I have a WiiM Ultra currently and I'm using that as my DAC and streamer. I love the fact that it has a sub out completely separate.

The 801 was on sale recently for $600 and the 701 was on sale for $500. This is 20 bucks cheaper for the 701.

From what I understand the 701 and 801 share very similar amps but the 801 has a better DAC (although in THEORY the DAC in the WiiM is better than either one) . Has anyone here ever compared the 701 and 801?

Yes, I said this is an integrated amp with subwoofer line out.

No, most(almost all/99.9%) of passive speakers do not have any filters in them for cutting out the low bass no matter what size they.

Any active subwoofer used with the 701 can only be used to manage its own low-pass crossover and settings.

Typically for high fidelity sound (the reason this retails for $800) you also want to remove the low bass from your mains(high pass them), even larger mains or you will risk over driving them at high SPL and having them produce distortion or worse. (Especially if you are using these with bookshelves/monitors or smaller towers.)
High passing the mains also allows for an easier/cleaner blending in of the subwoofer to the mains.

For example person A buyers some KEF R3meta speakers and an active subwoofer and wants to play loudly. Ideally you would cut bass below about 70-80hrz from the R3 speakers and relieve them of all that cone excursion that high SPL bass requires. Since this can not be done here, the person cranks it up and the R3 woofers are being over driven trying to pointlessly play loud 30hrz tones that only the subwoofer should handle and it sounds bad or even worse the listener doesn't notice this and blows the R3 woofers. This is true even with many tower designs, they are not meant for handling lots of low bass input from the amp and sounding good.

This is an issue with this integrated amp and a knock against it, that said it will not be an issue for all buyers. I pointed it out though as it is a limitation. One Yamaha should correct in new models at the same price point (some more expensive models have this taken care of).

Building actual bass management into the design would cost Yamaha almost nothing and bring these units into alignment with 2024 hifi goals and features.

I realize most SD buyers are casual in hifi , but If anyone wants to nerd out the ASR reveiew is helpful there are other bench tests of similar models in other hifi forums as well. https://www.audiosciencereview.co...iew.55211/

Well there are different opinions. You can search youtube for "High pass filtering the main speakers Paul McGowan" and see what Paul McGowan of PS Audio says in his video.
By design, in general, all passive speakers will filter what signal goes to its tweeters (high frequency) and woofers (low frequency).

That is incorrect. Same output for both. 801 has a better DAC and additional USB inputs.
