Carver Raven 350 Review (Tube Amp)
- Thread starter amirm
- Start date
I really want to like Carver products, And the 8 Ohm power of this tube amp is impressive... And it looks good.
But that's about it. Why oh Why not just build what the specs says it is supposed to be? I´m sure some people would buy it even at the current price if it did what the specs says and the higher order distortion was much much lower. And why not give it fairly descent performance in the "high feedback mode" like -70-80dB Second order HD. It should be a piece of Cake for Carver.

For the distortion nothing to say, of course it is such by design and many audiophiles want exactly that. The 4 and 8 ohm taps wired together and the absence of grounding are dishonest and scaring stuff, though. That should not happen, untolerable scam.

I'm sure your correct and it's meant to be this way... but why would one want a baked in sonic character that can never be altered?
If people are looking to play with distortion and noise levels, give this a whirl;
Much cheaper than this amp... or even a free one;

And even if you absolutely want a hardware solution, why is this distortion profile worth $4,750?
I bet it would be possible to built an in-line buffer with a nearly identical distortion profile using a jellybean transistor and a few other dirt cheat components.
Or you could get a cheap second hand PA amp and d¤¤k around with a soldering iron until you get the same effect.
I reckon this one distorts far less and sounds much better:

For something "as bad" as this it would be interesting to see the transfer function / linearity.
I can imagine it's doing a lot of dynamic range compression with long time constants.
(if the tubes get hot the gain goes down.)
But im not sure whats the right way to measure and visualize this

I see a lot in common with vinyl, although I've never owned a valve amp. There's a warm fuzz which strangely sounds like "richness" and "detail" instead of distortion. Look at the distortion results here <https://hometheaterhifi.com/reviews...t-art9xi-moving-coil-phono-cartridges-review/>

Of course, you need both. Which to choose, though <https://www.whathifi.com/features/10-worlds-most-expensive-turntables>? I also have an RPi streamer and have to say that no one would ever even notice it unless I pointed it out.

People who enjoy the mythos...
I am amazed at the power available from this tube/valve amplifier. Just out of curiosity what does all of that grass sound like? I don't have a powerful tube/valve power amp to try.

That may depend on how much grass has been consumed.
Bob Carver has some thoughts...
Amplifier Distortion (Bob Carver, 1973)
Results of an informal test project on the audibility of amplifier distortion, by Bob Carver (Stereo Review, May 1973) DISTORTION is one of those specifications that every- one talks about but few really seem to understand.For example, newcomers to the world of high fidelity frequently have the i...

It would be helpful to give us a total noise figure in dBV orNoise performance is decent for type of amp it is:
the 5w at is at 4ohms? so 4.4721V?
so ~13dBV so the total noise is at -75,5dBV?

No it is more of a warm smooth inner glow to the sound. Yes the music sounds the way the tubes look, and feel.
And, just knowing that you are listening to tubes will add some extra warmth too....

I own a valve-amplifier from EAR. It must be a better designed valve-amp because I don't hear any nice warm fuzzy sound. No richness either. I only hear a folded relatively rumbling bass, less clear treble and generally a bit weak dynamics. And a tendency to mush the sound in intense and strong parts. Not that it sounds bad, but compared to my Purify class D it is kind of tired. But it cuts in a pleasant way. On the other hand my class D does not cut at all.

Lets imagine you live in Norway and you are a Death Metal fan. Than this amp is not so bad.
Adding a liitel more crunch to the sound, while warming, in a cold norway winter, your feet on the tubes. Sounds not so bad.

How can you see you would hear "distortion" with this one?
maybe you would call it "folded relatively rumbling bass, less clear treble" or something like this?
How would "folded rumbling bass" look in the measurements
