Don't listen to them, listen to me, says the audiophool running 3 Yamaha AVRs. 
I bought them because of their reliability record and not because some "chump" who gets paid by audio manufacturers to wax meaningless hyperboles about the products they review. Im capable of independent thought, you‽Don't listen to them, listen to me, says the audiophool running 3 Yamaha AVRs.![]()
Which Yamaha sound? The bigger stuff sounds different than the under $600 stuff in surround receivers. The bigger stuff since about 2001 has sounded more like the 70s stuff. The stuff of the 90s was pretty bad to my ears. Thin and bright.I haven't gone very high-up on the product lineup which may sound different (or better) but I think of an emphasis on the mid to upper frequencies with a thin, bright, cold, detailed sound that sounds etched or 'metallized' for lack of a better term with some sibilance up top @ volume, similar to Onkyo I've also heard. I don't care for it and I also don't think it's very "natural" compared to more natural sounding equipment I've heard that doesn't label itself as such. It's like I'm supposed to be listening for the details when I am just trying to enjoy the fullness and richness of character of the sound that isn't there. Inter-connected equipment and others' ears will vary as will thoughts and impressions I suppose. I'd love to get my hands on some better Yamaha gear than the 80's/90's consumer-grade stuff I've heard to be able to hear something better from them because I've not been impressed and am sure they're capable of great sounding stuff when they feel like it. But like Sony, most of the time they just don't care.
The only truly mosfet receiver from Radio is the sta-2200That’s right! Radio Shack made receivers with mosfets in the early 1980’s. I’ve never been a fan of booming bass - case in point: My 1969 Lafayette amplifier was notorious for it. You could barely even move the bass control past neutral without the bass overtaking everything. Ernie, which Realistic models had booming bass that you remember?T
Except that one needs to vary the amplitude be it raised or lowered by at least a half if not full db over a large enough frequency range to get said house sound. That's how our hearing works. Everything else is just our mind playing tricks on us through personal biases such as sight as an example. I'm betting most people would not be able to tell differences through blind controlled listening tests.A DBT comparing receivers/amplifiers from the same era would quickly dispel your misconceptions.
Despite the mantra that a good amplifier should be nothing more than a wire with gain, A Marantz sounds different than a Yamaha which sounds different than a Sansui.......There is a "house sound" because each manufacturers engineers believe THEY have created that wire with gain. We all hear differently, engineers and designers too.
Yamaha's sound signature being discussed in this review of its $4,000 stereo receiver....
I swap between Forte IIIs and Harbeth SLH5+ speakers and the differences I hear are from the speakers - the amp seems to add nothing to the sound.
My arguement stands with SS and not tubes.Swapping speakers will absolutely affect the sound, that is a given.
The discussion here is about how the electronics before the speakers affects the sound.
The disconnect is in the misguided assumption that all equipment sounds the same regardless of manufacturer.
In an attempt to dispel this misconception I would ask if tubes sound different than SS gear, how is is inconceivable that different amps can sound different ?
Please attempt to explain away how tube rolling should make no difference then correlate that to how one manufacturers choice of components and implementation should sound exactly the same as another manufacturers equipment using completely different components and design ?
As I said earlier, there are a million way to make chocolate chip cookies, they are all different yet they are still chocolate chip cookies.
Tires are all black and round, but my new Michelin's are vastly different from my old Goodyear's???
But they are amplifiers none the less; by your theory, they should all sound the same regardless of topology or technology ?My arguement stands with SS and not tubes.
I owned a Yamaha R-V1105 for many years. Although some would call the sound clinical, I prefer to describe it a detailed. I actually preferred it to the Rotel RX-1052 that replaced it. The Rotel had a fullness of sound, but with far less detail than the Yamaha.
Amp/speaker pairing does make a difference. I have a Sansui AU-919 that sounds amazing, with one pair of speakers. And yet, a little to bright/brittle with another.
It matters not what others think, as long as you enjoy the sound.
Mosfet amps produce a more tube like sound. There may be a few out there, but I don't know of any receivers that used mosfet outputs.
)Depends on the age of the equipment. The early 620, 820, 1020 for instance we well defined, clean, clear along with the professional electronics. But when the 40 series came along with the switching power supplies and then the modular out puts it was down hill from then on. I retired in 05 only the professional Yamaha equipment still retained that smooth sound. When Yamaha went digital for HT processors the sound became worse, just like Denon, Marantz, Sony, etc. B&K had the best HT sound but the HT stuff wouldn't hold up. Mcintosh and other top of the line stiff sounded great but most folks couldn't afford it. I heard a Yamaha driving some B&W speakers at Audio Classics, this spring. What a horrible combination. The Luxman tube pieces were the best with the B&W speakers. Smooth and clear as glass. ,
The Yamaha "Natural Sound" disappeared long ago. Todays Yamaha does not have any more of distinct sound signature than almost any other comparable receiver. You can blame/thank HT processing for that.
At the time when "Natural Sound" was a thing, some people called it "cold" or "sterile" when compared to Marantz, Pioneer, Sansui, Kenwood etc. At that time(mid 70's to late 80's) every manufacturer had its own house sound. Even though an amplifier shouldn't add or detract from the original signal every manufacturer has their own recipe. Its a little like chocolate chip cookies, everyones grandma has their own recipie and even using the same or similar ingredients, somehow they all taste different.
If you are happy with what you have and hear, then enjoy it for what it is and dont worry about what someone else thinks it should sound like. You are the only one who has to enjoy your system.
(Although I haven't drank in decades)I said solid state. Variances in tube manufacturer are many magnitudes higher than solid state devices so by my own admission, Im taking anything tube related out of the equation. If you choose to ignore the variances caused by tubes, thats your perogative but dont twist what Im saying.But they are amplifiers none the less; by your theory, they should all sound the same regardless of topology or technology ?
My correlation of tube rolling vs the choice of transistors, capacitors and resistors affecting the sound signature of a piece of gear explains the potential how different pieces of gear can sound different.
