Chip amps compared - Page 7

Thanks for posting this, Mike.

British amps are usually under-rated in specs (power, distortion, etc.), and you sure can trust what they say as a minimum.
Japanese are the opposite, usually.

I cannot understand how one can say an amp is no good without listening to it.
Also, a so well know brand as DNM should be known by those that "know it all".

Most Linn power amps use chips (TDA7293), I've heard them and they sound very good.
I'm sure plenty of people will say it's impossible, but they are exactly those who haven't listen.

Jan,

I am almost always with you

P.S.: Is that you on the avatar now, finally?

janneman · 14th November 2004, 06:53 PM

Nope, not me.

This is a copy of an earlier post (you are not reading all posts, are you? tsk, tsk..)

"I like pics from people I admire. This is Paul G Allen, 2nd man in MicroSoft. Has only 1/3 the money of Bill (only 20.1 Billion $ US).

Eight years ago he decided to built a provate spaceship. Last week the ship made it's 3rd flight, and won a 10 million $ prize for reaching a certain altitude & duration in space, sub-orbital.
In 2 to 3 years he will offer tourist flights in space with Richard Branson of Virgin. ( http://www.virgingalactic.com/who.html and http://www.space.com/missionlaunche...an_archive.html ). You can sign up for it already. I hope I can afford it before getting to old.
This kind of people, with a vision, and then realizing it, I admire very much. Of course, it's all subjective

PS I signed up for a trip. Don't know the cost, so probably it'll not fly (pun intended), but I can dream, can't I?

Carlos, you'r sinking again!

What do we have here:
Why should I trust an amp because it is a British design?
"Well known brand" what does that have to do with sound?

many people are commenting but only two in this thread have heard it.

so the simple truth is most of us don't know what we are talking about

We don't know what the distortion figures are - all we know is that at 20kHz, full power, it is something below 0.1% but we don't know how much below or at what impedance load. All in all not much to go on.

and lets face even if we had all heard it we would still probably disagree on what we thought about it...

But I still have a hunch that Upupa Epops would like this amp it he ever gets to hear it.

over and out

Maybe you have noticed that most of the comments were not on the sound of this amp as such.

mikelm · 14th November 2004, 07:24 PM

of course - how can you comment on a sound you have not heard.

I think this little bit of this thread was fueled by Upupa Epops dismissing an amp that he had not heard - I for one thought that this was a bit odd.

I have not heard it so I am keeping an open mind

Huh?

I was just talking about the meaningless specs.
0,1% THD without specifying the frequency is as meaningless as an 8ohm "average" rated speaker.

Again, I was not talking about the sound.
I was just talking about a well known brand, unknown to a member, nothing more.
Have you heard DNM amps?
I didn't, so I refuse to comment on the sound.

I like Upupa as a person and as a member, but unfortunately this has been his attitude lately.

That's really it.

O.K., I started this confusion, as I remarked DNM amps as very good amps and compared it with my gainclone.

Today, I had the chance to compare my GC with an McIntosh (I mentionend the type a few posts before). There is a difference: the Mc had some sound, I know for the last 30 years. It was like sensing a taste, you missed some times.

This is the typical SS sound, I dont like. Missing dynamics. Maybe to much feedback? Everythink O.K., but where are the details? The soundstage is missing.

I prefer GC and I actually could not buy a DNM

BTW: My 300B Single End is still idle in a corner.
