It will be too small to justify the spending. WiiM proposal whose more for PEQ and room EQ but if you do that on PC (and lot better) them you don't need it. R-N 1000A is good enough to ditch the DAC and PC but price ain't great. Perhaps invest in speakers instead.
Investing in Speakers?
Ma Silvers are as wonderful as flawless. If I spend 4 times the money, I can't get 1 times the difference. This Speaker is 60 thousand Turkish Lira in Türkiye

This one's?
Just last weak I helped your countryman to chase down Revel F36's that went on outlet (and he did for 2050€), he is importing R-N1000A from Macedonia. I am aware of hyper inflation (got trough worse one) and prices in Turkey. Invest in something that will make difference and it doesn't have to be big investment sometimes. Do you own measurement microphone? If not there is idea and with it see to find; better position for speakers, eventually limited accustic treatment (heavy curtains, rug, diffusers...) and EQ.

You are a wonderful person, very knowledgeable and caring, thank you very much.I use 100g 7 not 50g My acoustics can be said to be flawless. 2 walls, thick curtains, rubber carpet tiles, 2 giant acoustic panels. I think that's my only problem. I'm having unnecessary worries because I've just switched to a very good system for the first time, saving money seems like the best thing to do.
 
Yamaha is a company that does everything well, but nothing great....and yet all of us love them. That tells you a lot, right there.
 
I have a technical question for anyone that owns either the A-S701 or A-S501 and a multimeter - can you see any DC voltage present on RCA Inputs (not outputs) for a short period you turn off the amplifier? On my A-S501, RCA inputs show about 35mV of DC voltage right after the amp shutdown for about 30 seconds after I shut the amp off. Then it drops to zero.

I’ve seen this type of behavior on other amps before, but usually the DC offset dissipates much more quickly (1-2 seconds).

Thank you in advance for indulging my curiosity if you are able to measure this.

There shouldn't be anything wrong, since the inputs are AC-coupled. At least on the A-S700. Perhaps a defective capacitor.

Hi Ralf, thanks for responding. I’ve measured another Yamaha receiver I own (htr-6063) and that one has the same “issue” except the voltage is 60mV DC, but lasts only 10 seconds after shutdown. It’s unlikely they both have defective capacitors.
 
When turning the device on or off, the voltages can jump in all directions. This probably causes the coupling capacitor to charge and then discharge through the drain resistor. Nothing to worry about.
 
Hi all, I’m almost at the point of going from Fosi V3 to this Yamaha 701, but what should I get the Yamaha or LPA-S600NCX I have a Schiit Saga 2 preamp already? Speakers are: Wharfedale EVO 5.3 - Fosi sounds like it has no control over the bass and lose it at higher volumes. Yamaha would sound great at low volumes with its dynamic loudness and the HypeX is great value too but it’s not a integrated and double the price of the Yamaha. I’m hoping you all can help me ;)

What room correction are you using and what you hope to achieve? Are we speaking about new or used A-S 701 and at what price? Are you using sub's?

Wiim Ultra for room eq. I have a sub SVS Pro 1000 but kind of like the idea of an integrated amp. But HypeX NcX500 also looks great for the price and might perform a lot better than the small toasters Fosi V3 Yamaha looks good and has the loudness feature - reason for asking I. The 701 threat here - one thing is measure another thing is how it sounds ❤️

Not sure would ELC (or Loudness how Yamaha pelrefer to call it) work to sub on A-S701. It's nice amplifier which would serve you a long time, old A-S700 whose better regarding unbalanced input stage. I do DSP-ing on PC (JRiver) and run 2.2 with ELC in ISO 226 2003 form. In order for ELC to work good in the first place 2.2 is requirement (if you ask me) and remember those EVO's all do floor sanders are still 2x 5.25" woofer (each and 105 Hz knew to 120 Hz crossover it's barely reaching their cone limit [flare and reinforced or not]). In other words power amplifier will change a little of what you complained about (as usual).

this, right here ;)

I own an A-S701.

I've been reading/researching a lot about HypeX/Purifi, and other amps (integrated), wondering if I might find gold by switching the Yamaha (you know, because power this, head room that, power reserve...). But then I think to myself, again and again, that there's absolutely nothing wrong with the A-S701. Well, the on/off switch has always been flimsy... feels really cheap, actually. But as for the rest, it works wonders, has power that I will probably never ever use in my life, and I'm really enjoying the music that I listen to.

It's paired with a pair of Triangle BRO3, which I may change at some point with some BRO8, but that's still just a project. You're gonna say that the Triangles didn't measure well, Erin says so, don't really know about Amir, but for my budget, I can't complain. I can EQ the A-S701 if need be, but I usually use it on pure direct mode.

So, all in all, I believe it's going to be quite difficult to part with the A-S701, since from my not-so-audiophile-gear-head-and-not-rich point of view, it does everything right for the price. What can I say...

I have a Yamaha R-S700 receiver (essentially the same amp section as the A-S701) that has Preamp Out/Amp In connections. This has allowed me to test out the R-S700 amplifier driving my Yamaha NS-1000Ms and my ADS L-880II directly as well as using the R-S700 preamp section to connect my FOSI ZA3 amps either in stereo or in mono configuration. After various tests I just don't hear that much difference in Amplifiers either in power or clarity. I must say these speakers seem to be pretty easy to drive compared to some Vandersteens that I had. I am using the ZA3s with dedicated 10A 48V power supplies. I do love the Yamaha variable Loudness and the trigger out for the amps.
 
Fosi sounds like it has no control over the bass and lose it at higher volumes.
If that is what you are hearing it has nothing to do with the FOSI and you won't get any improvement with the Yamaha.

This will be 100% speakers and room interaction. Or poorly implemented room correction.
 
I just got my S-A701 and replaced my FOSI V3 Mono's + Schiit Saga 2 and what can I say, even my mom said, wow this sounds alot better without knowing anything in reagrds to sound. It simply opened up, no need for heavy EQ in my WiiM Ultra now EQ is off and it sounds fantastic. Speakers are: Wharfedale EVO 5.4 - bonus is no need for all the extra wires and a more clean setup, it's impressive how good of an amp this is for 618 Eurs on Amazon. I also tryid to test the DACS i have, Yamaha build in, sounds fine too me, vs the built in in the WiiM Ultra plus my SMSL-SU1 and honestly again, they all sound great - hard to really pin-point. Now I'm wondering if i just stay put, or try one last upgrade going for lets say a Topping E70 Pro plus or E70 Velvet, but again I'm not sure i might hear any differance, and I'm not hear too hunt the last 5%. I need upgrades that can give minimum 25 % extra, like the Yamaha did, this was too me and insane differance in sound with my speakers, I'm still trying too understand how great it is, and how powerfull it is. This will give alot of joy, the next many years. The Fosi V3 is nice for what it is, but they are not going into my main system again, might end up in the kitchen too make egs on them as they are this hot. Yamaha is cool as ice compared :)

Was your Mom in the kitchen by any chance?
 
what's happening in ASR? :-)
we try all the time in all topics to always check the mental bias and the normal real source of differences (gain / impedance/ whatever) ... and in the last times we're more like stereophile.
What we're doing wrong?

You cannot get the real difference on electronics with a sighted test and without any check on technical parameters. Done ... please.

I had the Fosi V3 as a power amp in my chain, preamp always was the Yamaha A-S 1200. I switched a few times between the Fosi V3 and Yamaha A-S 1200 poweramp, but couldn't hear any difference at all with the Linton 85th.

Using a NC252MP based poweramp made a difference in hiss, i was able to hear the preamps electronic attenuation click when putting my ear to the tweeter at full volume. The Fosi and the Yamaha poweramps had more hiss so the clicks where not audible. But again, no difference when listening to music. I guess i'm now in the group that says any amp that is competent sounds like any other amp that is competent.

I'm not saying that what you heard wasn't there, just that i didn't notice it with the "bigger" model. If you could hear it, you should verify by measuring it.

in addition to measuring, I think he should check everything to ensure if he’s comparing apples to apples.
