Ooops!

The truth of this assertion may be verified by a study of the circuits posted by the Levellers here on DIYAudio (ie those that repeatedly attack anyone asking innocently whether one type of component is likely to sound good or bad in a given circuit position). Their designs, if they even present any, are certain to be lack-lustre recycling of decades-old work.

One of the best statements I've seen here recently...😛

Rod, you made the claim, you back it up. That's the way science goes, but perhaps you don't know a lot about that.

Surely you are not too lazy to do your own homework?

I already addressed your point.

Nothing could be easier: show me some circuits worthy of the advancement of the art, and we'll have something to discuss.

But you appear to wish to degrade the debate into throwing of personal insults - the surest sign of somebody with nothing to contribute.

Hi,

Don't tell me you have had a happy life with all dunk sounding tubes, you replaced some of them too, honestly?

I'll be the last person around to claim that all valves sound the same but I've never wanted a bright sounding one.
If you do then there is a problem elsewhere that needs fixing.
IOW a bright sounding valve is one that quite likely has a frequency response deviation and hence is not linear.

That said, I'm not aware of manufacturers who deliberately manufacture bright or bass heavy valves for that matter. I do know that some brands or batches distort more than others and so on.

Ciao, 😉

Maybe that person meant "clear" or "more transparent" by bright or brighter, which are very well understood since the times before you and me, which was in a post just few days back here.
That is a subject on its own which has nothing to do with tone control, but deliberately confusing it as it may is humorous and even sounds clever, but I don't think it makes anyone who does not subscribe your point naive either.

That wasn't the general impression. That same person also started another thread previous to the one you refer to asking the exact opposite so it is reasonable to assume he was after a tonal balance adjustment.

Either way, be it passive or active components, you could all pick them to suit your system or your personal taste. Be ware though that that method won't necessarily give satisfactory results in any other given system.

Any component with obvious tonal deviation from neutrality should be avoided.
Any component which lowers distortion and/or noise levels is welcome. No?

Ciao, 😉

Depends on what your objectives are.

Personally I tend to the view that if I am going to use valves it is because I **WANT** something that distorts in a nice way and that may or may not be particularly flat, otherwise I would be going for a fast solid state stage with 50++ dB of GNFB and bucketloads of voltage headroom.
Sometimes that is absolutely the objective (Instrument amps often fit into this category), in which case obvious tonal issues might be just what is wanted, and picking parts with deliberately horrible parasitics might be a win.

A low distortion valve power amp is certainally possible, but is a lot harder and more expensive to pull off then using valves for a more distorted sound (that can be very pleasent) and using cheap sand for a clean amp.

Regards, Dan.

Who says you can't have both using valves?

People seem to associate valves with distortion. A guitar amp thing?

If you want a more neutral resistor (and it won't come close to a Charcroft, that's for sure) then I'd recommend the old Holco and Caddock resistors.
Be ware of voltage and wattage restrictions however.

I read one listening test in a magazine of various resistors and they rated Holco the highest.

Holco only cost a few cents. A lot of these highest-end components only cost a few cents at times. I believe a lot of low-end is, likewise, very, very expensive at times.

To repeat, I am playing the ball, not the person - but it is the ball here that is allocated mystery abilities with no data/proof whatsoever of reality. While hearing is subject to characteristics outlined in the above studies, electronic components are subjects of science, quantifiable by present-day equipment and techniques to exactitude far in excess of what human hearing can discern.

I will be the first person to adopt this component or that if any proof can be furnished of its superiority to the next. Thus far I seem to find only reams of anecdotal perceptions.

Yes, this is an old subject, but kept alive simply because of continued rejection of facts.

I'm sorry, how do you know there isn't hard scientific evidence somewhere in this earth, that Tantalum resistors sound different?
