Violectric HPA V200 Why not sufficiently appreciated?? - Page 4

someone on the forum said that talking about sound was like dancing about architecture...and there' a manufacturer that says that listening to cheapo opamps is like listening to an orchestra through a key hole.

what is coloring the sound the most is your V100 is -more than likely- the cheapo 5532's. do you find it normal that the sound of a $600 amp goes through $0.3 opamps? seriously?

You don't seem to have much experience in rolling opamps, and you can rest assured that you ARE (most exclusively) listening to the 5532's when you turn on your V100.

here's an attempt from Ray Samuels(another amp manufacturer), trying to explain what the LT1028 does to your sound(it's one of my three favorite opamps): REVIEW: Ray Samuels Emmeline HR-2 - SGHeadphones

that's what LT1028ACN8 does. really.

it's expensive, and I think it's still a hell of a bargain(and should have been priced 4X higher to be taken more seriously )...I'm sure the V100 would be eye popping w/ a bunch of these. try it, become a believer...don't be afraid...well, actually, be very afraid because the SQ will be a night and day and you won't quite be able to turn off your amp anymore

PS: about your DAC question, same answer: Heres some test results for the new ESI Juli@ card. [3] - RightMark Forums

the OPA2134 in your Matrix DAC are ruining the SQ completely

I am afraid, according to the description what these amps that you suggest do like

As Mr. Samuels once remarked, the LT1028 is like putting sugar all over your sound

they would not help a bit in the quest of reproducing the sound as close as recorded.
I do not wan't sugar all over my Mozart, Hydn, Stravinsky etc nor cream or dope. I do not fry eggs when I listen to music - so I strongly believe a tube amp is superfluous (the second one you suggest) .

And also I do not need military grade components & wire in my amp.

The temperature in my room is average 18-20 dgs cent. So no freezing and towing cicles that can screw the components and make them unstable.

Can you suggest an amp that can help HD speak the truth ?

you're only as strong as your weakest link, and your Matrix DAC is full of OP275/OPA2134: http://www.head-fi.org/forums/6389249-post2173.html

I've heard the 5532, the OP275 and the OPA2134, I an well aware of what they are (un)able to do.

anyway, you're happy w/ your current gear..enjoy!

Excuse my ignorance but if somebody want to replace the 5532 with the AD797BRZ how can you inster it in the sotckets if the pins are like in the picture?

AD797 is a single opamp, NE5532 is a dual...Fried told me that it should be a drop-in replacement in their Violectric line.

just get a bunch of these: Dual to Mono Op amp module NE5532 to AD797BR - eBay

the square pin at the bottom left, always!

you can read majkel's impressions about the aforementioned opamps here: http://www.head-fi.org/forums/f6/aud...1/#post5238657

I don't know what your problem is. You said it yourself here:

http://www.head-fi.org/forums/6400420-post132.html

Don't look at individual components, or better yet, don't read blogs or posts of individuals having 5 posts and think they are better than you. You are better than that. Look at the total package.

The $330 Matrix has dual AD1955 and the $1,500 Lavry DA11 has single. Is Matrix better than the Lavry?

The $330 Matrix has OPA2134 just like the highly praised $3,500 LessLoss DAC 2004 MkII. Does that make LessLoss sound the same as Matrix?

Didn't you think that the AD1955 has very good transparency and imaging that the designer complement the system with OPA2134 because of it's good bass?

I suggest you spend your time listening than commenting on a set-up that uses this and that component.
post #51 of 339
I don't know what your problem is either? are you this bored to look up all my former posts?

yes, I had faith in humanity at the time, and believed all the clueless feedback about the Musiland 02US...which appeared to sound like ****(just like majkel predicted).

I suggest you spend your time doing better things than playing Sherlock Holmes, because it doesn't fit you too well and won't be very rewarding in the end anyway.

if you want to listen to crappy opamps, it's your very own right...as it's a free world. OPA2134 can be used for DC Servo, then it wouldn't matter. anyway, as I said earlier 5532/2134 are prolly the most boring opamps...if you like a boring sound, you'll enjoy yourself I guess

I've compared 2134 to 2132, and each of these 2 opamps has 2 grades(the 4 models come from the same waffer)...why those units you mentioned don't use the higher grade of 2132 is pretty easy = saving money! and there's no way any of the 3 lower grades will ever "sound"(I said "sound", not "measure") as good as the OPA2132P/U.

As already said, do not know what is inside Matrix, but it sounds better than Bel Canto Dac 3 /2200 Euro/ and Aqvox /1100 Euro/ which only shows that making a good DAC is no rocket science ...

here's some honest feedback about 5532 Vs OPA627: http://www.head-fi.org/forums/6522165-post2424.html

but maybe he's also imagining things

HA HA HA
I was searching for the HPA V200, encounter this thread,

Leeperry, I really can`t believe what a TROLL you are..

Any experience with HPA V200 and HD650?
post #55 of 339
Comparing op-amps in different circuits will yield different results. I have listened to the 2134, 5532, and 797 extensively. Heck I have several of them in my op-amp storage box. I can not say that in all situations the 797 is the best, nor can I say the 5532 sounds poorly. Depending on the circuit I may prefer one over the other.

There are some good sounding op-amps out that we may not have listened too. In a site I frequent a member hates the LM4562, yet I find it is a very nice sounding amp and one I have found to perform quite well.

I guess at the end of the day, it is like comparing chocolate to vanilla. Either one is fine depending on the listener's perspective and the circuit being used. Cheers.
post #56 of 339
I'll take OPA2604 over LM4562 anytime of the day
post #57 of 339
Good to know! But we are back to chocolate versus vanilla, neither is wrong and neither is right for all/any application.
post #58 of 339
I don't really agree, LM4562 is very limited IME...and opamps color the sound far more than anything else ever will...like DAC chips for instance: http://www.head-fi.org/forums/6490323-post3.html

opamp'holics like Andrea of majkel also came up to the same conclusions: http://www.head-fi.org/forums/f6/aud...-v-2-a-397691/

AD797B/LT1028A/NJM4580D/NJM5532 always sound identical each time I pop 'em into new designs
post #59 of 339
Well their experience although it may mirror yours it does not mirror mine. And although I have not posted all my results I too have done my fair share of op-amp rolling but the results can not be the same since we all hear differently. I am just glad we have all these great op-amps to try as compared w/ 25 years ago.
post #60 of 339
mrarroyo has often expressed a calm opinion that I agreed with in the past

and he has done it again! Hear Hear!

I enjoyed swapping all of the mentioned opamps, including the very nice 17-transistor discrete Burson opamp 8-pin plug-in, years ago in my RSA XP-7 and a Rotel 965 CD player, and they are all good candidates, as Miguel said, depending on the rest of the circuit

and depending on your EARs

so listen, then choose - and having a choice is great!

and if you've actually heard the V100, and done some opamp rollng, then please share your choice

but if not ....
