The live with Burson Audio op amps V6 Classic

I spend some time with the Burson Audio op amps V6 Classic and I confirm that replacing regular op-amps with these discrete devices gives a ´´step´´ up in sound.

The test op amps:
LME 4562NA
LME 49720NA
LME 49720HA
Burson V6 classic dual
LME 49710HA on dual single to dual adapter

Before receiving the Bursons I used most of the time the LME 49720HA and this will be the benchmark on this test.
The op amps will be tested on Active filter 4. (

Once I used the Bursons on lower frequencies and LME49720HA on high freqs.
Then I used the LME49720HA on lower frequencies and the Bursons on high freqs.
The bass is more real, it sounds more homogenius, deper with the Bursons. The middle is full of details, but the background has more details with the LME49720HA. On high freqs the Bursons are relatively detailed. I was able to hear some differences between the two opamps, the differences are very small. They are both very nice opamps, the Burson V6 classic is warm, smooth, detailed. I can only recommend it but it comes with the price.

I got a chance to try two pieces of Burson Audio V5i opamps and these were delivered to me last weekend.

Below are my quick observations based on using V5i for less than two days (say 10 hours in total) on three products: M-stage HPA-1, Topping D50s, and Xduoo xd-05.
The V5i fitted well into these dac/amp enclosures. However, given their larger size than the usual opamps, V5is may not fit in some DACs and amplifiers.

In the last five years, I have used a wide range of opamps. Currently, I own the following opamps:

Muses 2

Out of above list, my current favorites are Muses 2, 1612, and Opa 827, in that order. Given the time constraints, I could not compare V5i with all opamps listed above - except Muses 2 and 1612.

What about sound quality? To begin with, there is an improvement in the soundstage in comparison with Muses 2 and 1612. The V5i provides a wider soundstage than almost every opamp that I currently own. There are more spaciousness, instrument separation and clarity compared to Muses and 1612. I found V5is to be mid-centric opamps. I also noticed an improvement in low-end definition with lows fast and dynamic. Highs are clear.

To my surprise, V5is don’t sound too technical or soulless, as is often the case with some other opamps having similar characteristics.

Now the obvious question: are v5is worth the money (US$39 each)? Well, it depends. If you already own a mid-fi music system with the better source material and would like to fine-tune the sound signature at a little cost further, then yes. If you are a fan of vocals, pop, and jazz, then yes. If you have just entered the opamp rolling hobby, then my suggestion would be to begin with cheaper opamps available on Aliexpress and then gradually move towards expensive ones.

My take: I would buy expensive opamps (such as V5i) rather than spending an equivalent amount on replacement cables.

What about battery consumption? As I could not spend a considerable amount of time testing these on Xduoo HP amp, I am not sure about battery consumption. I may check it in the coming days and update here.

I am told that Burson Audio offers a lifetime replacement warranty on its opamps, which perhaps no other company offers.

I shall be soon testing V5i on Asus Essence One and other products and would be happy to share my observations here, but that may take a few more weeks as I need two more V5i opamps for testing.
I forgot to attach pics in my above review of V5i opamp.

Pics of using this opamp in Xduoo xd-05 and M-stage Matrix HPA-1 are attached in this post.
