Default My experience with the Burson V6 "Vivid" opamps

Hey there. I recently received a set of Burson V6 "vivid" dual opamps for testing out from SSaudio, and am writing up my experience with them. Most of you might find it a bit strange seeing me outside of the Tubes/Valves forum

This is the first post of several (an introduction, really) so that I can get the ball rolling on getting the review up.



First off, let me state that I was offered these samples for testing without charge, and that I am not being offered any compensation for my review, I simply agreed to post up my experience with them in return for being sent samples. I do not sell them, and am not profiting off of this review in any way.

Second, let me say that those of you who have seen my posts may know I do not mince words. If I think something is poor quality, poorly engineered, or downright stupid, I will state so, usually pretty clearly I wont be giving any headstart to these simply because they were free, or based on reputation or "perceived" quality. I will be as honest as possible.

So, here we go...

I do not own very much solid state gear, and don't buy much pre-made gear. My intention in trying these out was to see how they perform in DIY projects specifically, as that's my focus in audio overall. I do not currently have any test equipment other than a DMM and my ears. I'm very much an "average" guy so far as this is concerned, and on a budget too. If anybody else wants to try these out and run some real tests on them, drop me a line- I'll gladly lend them out so that you can run THD+N measurements.

My first setup- as pedestrian as it sounds, is a Basic CMoy circuit used as a general purpose preamp. The only modification is the use of a TLE2426 rail splitter reference to an OPA134 active ground scheme. I usually run my favorite opamp here- the OPA2132P. It's quiet, clean, and sounds good, with a characteristic dark/mellow Burr-Brown "signature" that I happen to think sounds flatter than some more expensive opamps. I also have a pair of OPA627 on a browndog adapter I run on occasion, although it's a trivially simple circuit for such a fancy chip. It performs excellent in this preamp, but it doesn't really shine too much better than the OPA2132 in this application- maybe for use with very clean reference monitors, or very nice headphones. I also have a selection of other opamps on hand I will call out on occasion for comparison.

Second setup- Full-range speakers with tube power amplifier. Speakers are dual Faital-Pro 3FE25-16 in a .53X scaled Karlsonator speaker constructed with foamcore, from the now legendary thread in the Full range forum. Power amplifier is a DIY 6N1P/6CW5 push-pull setup. Regulated screen voltage, concertina splitter, and solid state rectification with mosfet ripple filters. Very quiet and clean amplifier, capable of ~22 watts or so before soft clipping occurs. This combination is on 12+ hours daily as our main sound system, and is very "transparent" with any changes upstream being quite noticeable. It is usually used with a Samsung Galaxy Tab 4 tablet as a source, directly connected.

Third setup- PCM1794 dual-mono DAC, on a "HIFIDIY) PCB. The PCB utilises dual-opamp footprints for the I/V conversion with datasheet values for the resistors and capacitors associated with them. This is the primary reason I wanted to test these opamps, as I don't like traditional opamps for I/V conversion all that much. Here they use the NE5534 or dual NE5532 on adapters, although I have also used a few others here as well, and will call them out as needed for comparison. This gets it's signal via a CM6331A USB board.

I also have a few other projects I will try them in, and will update the posting as I go.

Next up- I'll post my initial review/impressions of the Bursons themselves, and we will go from there.

I have used monolithic and discrete opamps significantly in R&D over the last 5 years. The V6 Vivid are close to being the most transparent (only second to Sonic Imagery 992/994 discrete bipolar). The Sonic Imagery is very demanding on the power supply. The Burson are not quite as demanding, but they won't perform best unless they have a very localized power supply capacitance. See if you can put a 100uf Nichicon FG across the +/- rails right at the op amp location (bypassed with a .1uf MKP of course). Or even some 47uf on each power rail very close to the op amp.

Hi friends
IC3 and IC4 of deq2496 were used in output buffer
amplifier sony ta fe600r player ibasso dx90
I tested the deq2496 at flat settings when you plug it into the device, the AB class will sound like A class from A amplifier. A remarkable point,
The V6 Vivid Opamps have a very vivid voice. Neutral and detailed sound with a tight bass effect dynamic field perfectow and medium tones are very accurate and have exactly as needed. Bass is quite low and deep
The V6 Vivid has a clean and clear treble response.
Highly dynamic, impressive and detailed musical.

Sorry for the long wait, severe lack of time and persistent hand tremors have kept me from spending much time with a soldering iron, and DIYaudio in general. I managed to almost complete a board that I plan to use these in, and of course now that I've gone to take pics the Cmoy amplifier I built for these is missing

This is just some preliminary pics to show how they are shipped, and the size compared to other options.

They ship in a nice little snap-shut plastic case, with a dense, tight-fitting foam insert, very nice attention to detail honestly.

They come with a pair of gold-plated DIP8 sockets, which is a nice addition.

They also are potted in epoxy at the bottom, and feature nice machined pins-

The case has ventilation slots at the end, and you can see two internal PCBs. With no openings on the bottom to draw air through I'm not sure how effective these will be, but they don't seem to run all that warm so I don't think thermal issues will be a concern.

My experience with the Burson V6 "Vivid" opamps-img_20190602_102252-jpg

They do feature a prominent notch along the entire length of one side, corresponding to how they are located on most "standard" DIP8 opamps. It'll be hard to miss which side is which

My experience with the Burson V6 "Vivid" opamps-img_20190602_102307-jpg

Here's a shot of them installed on the in-progress DAC I'm working on. Nice comparison between single opamps, dual singles on an adapter, and the Bursons. These guys are tall- twice as tall as the dual single adapter boards once installed.

My experience with the Burson V6 "Vivid" opamps-img_20190602_102720-jpg

They are however quite narrow, which may work out well for installation into commercial gear where the chassis may be large, but board space is cramped-

My experience with the Burson V6 "Vivid" opamps-img_20190602_102709-jpg

Initial listening impressions in the Cmoy were good, but the DAC isn't ready yet to comment there, of course. I'll dig for the Cmoy and get some pics soon. Initial listening impressions there are that you really want higher voltage for best sound, two nine-volt batteries in series worked well. Sound very, very close to the OPA627/637 opamps, but with their own signature that's hard to explain. Laid back, but detailed? I'm really bad at those sort of descriptions, but would love to put these on a THD analyser setup, and see what the frequency response is like.

I have a two (three in two weeks!) Year old pestering me to go for a ride, so that's it for now, I'll try to trickle in more soon. I have a bin of parts I'm looking for that contains the half finished PSU for the DAC that is hiding from me currently too, so I need to tear my parts stash apart and go diving

Interesting, yours have a bottom lid of sorts

I honestly wish mine weren't potted, I'd love to get a look at the internal construction of these.

Burson V6 Vivid

Before I start writing a review of my listening impressions of V6 Vivid I would like to thank Charles and Burson Audio for their generosity to supply me with the last generation of V6 op amps.

The package arrived in excellent condition with a delay, I suppose due to the Easter holidays or slower postal procedures but without any problems at customs.
Speaking frankly as an old Burson fan who has over 15 op amps (as you can see from the attach.) starting from the older ones like V3 generation, through V4 and V5 I was expecting that V6 should be on step further in sound improvement.

My main Hi-Fi rig consists of Audio lab M-DAC, diy tube preamp with 5687 tube, Primare A32 Dual Mono Amplifier and Pioneer/TAD S1 EX loudspeakers which I consider as a very analytical system. Also I have another active system with P.Audio concentric mid/high loudspeaker and Beyma 15” bass. And of course DIY active x/o fully moded with three generations of Burson op amps ! Music that I listen is mostly classical and orchestral jazz.

So I decided last month firstly to change op amps in my DAC and as I know my sound quite well was expecting to hear difference immediately.
Originally DAC was equipped with NE5532 and NE5534 op amps which I changed them two months after the purchase with Burson V5 generation. So I took V5 out in the I/V position and installed V6.

The sound...hmmm...The first impressions of the jury consisting of two old and experienced audiophiles, one professional musician – prof. of clarinet and myself is the holographic 3D stage, huge as a trunk of a Cadillac. It is the difference that is obvious at once after the first 2 seconds.
Also I know from my earlier experience in capacitor testing that Mundorf Mcap Supreme Silver/Oil caps can produce an excellent three dimensional illusion and I put them in place of my FT-3 coupling caps at the output of the
tube preamp. And that was the situation I have never experienced before. Simply stunning! A very good combination regarding 3D stage. But something was missing and the sound after a longer period of listening became fatiguing with metallic and sort of aggressive ingredient among many others virtues. Yes...the dynamic was better comparing with previous V5 or NE5532, sound had more details with controlled bass.Sincerely speaking I am afraid I was listening to highs with a lot of sibilance which shortly after became annoying.

But I remember I read somewhere that Bursons need 100 working hours for burning in to show their real nature. Was that recommendation coming from their technical team or not can’t remember really. And I spend the last 15-20 days listening to a local FM jazz radio at very low level.

Last week the jury gathered again and we played our favorite music. The change of the sound was obvious although I admit I was not firm believer in burning in of opamps. For loudspeakers - yes that is rule but for the rest of the electronics...hmmmm....I don’t know...simply can’t explain....
Now I am positive! Vocals especially females lost their aggressiveness, acoustic and amplified instruments sounded more natural and the bad recordings show their bad sides. The overall sound was with a lot of details and with balanced smoother character. Everything was enjoyable and non fatiguing.

Next couple days I continued listening to different musical material and mostly was impressed with the female vocals coming through Vivids. Perfect harmonic rich structure. The voice of Natalie Dessay was like never before – clear and rich.

After a week I moved and changed complete system with active x/o and PA drivers.
Put all Vivids alternatively in high pass, band pass and low pass sections and listened carefully. There was always significant change in the sound overall mostly noticed in the midrange and in this system it was consisted in details. I suppose it was due to the higher sensitivity of the drivers. A lot more information, more tiny details than previous BB2604, V3 and V5 had reproduced. Bass was also punchy, deep and veeeeery fast ! Highs were very extended, clear but with a pinch of aggressiveness (these are by the way PA drivers…!) which I suppose is welcomed for those listening heavy metal or rock music.

So are these V6 Vivids worth the money?
First it is all dependable of the quality of the complete Hi-Fi system what and how much will you hear the difference. My system is highly transparent and can show every change in the chain. Or if you put it in another way less expensive and lower quality electronics and loudspeakers might not show such a big difference. So be careful!
Anyway Burson Vivid V6 are excellent op amps and I highly recommend them.

Regards,
Yugovitz
