Ideally would be to swap the old ones with the new ones, all six of them, but if you want to invest less you might try swapping the two op-amps from the Voltage Amplification Stage (the Gain Stage). Below is a V7 Pro Classic op-amp placed into the socket position that changes most of the character of the sound.
That’s very helpful! Hopefully they go on sale this week or soon. My plan is to get 2 Vivid Pro, 2 Classics, and either leave the V6s in the volume control buffer stage, or if the prices are fair enough, just get 4 vivids and 2 classics. I could hopefully transfer those to the Voyager when I order one down the road. Thanks again for the informed findings.Ideally would be to swap the old ones with the new ones, all six of them, but if you want to invest less you might try swapping the two op-amps from the Voltage Amplification Stage (the Gain Stage).

V7 Vivid in the Input and Output stages and V7 Classic in the Gain stage
When mixing V7 Vivid with V7 Classic op-amps the 2nd and 3rd harmonics are a bit higher than using only V7 Vivid or only V7 Classic
I feel that sound gets even better in this combination of op-amps, perhaps detailed and organic at the same time, but it's hard to tell much right now because it's too late and I'm tired, but I'll try next days to do an A/B test against another audio device, write down the differences (if exists), then swap the op-amps and write any audible differences again.
For the moment, my favorite combination would be one from above.
What are your subjective impressions now
V6 Vivid vs. V7 Pro Vivid sound measurements differences
I got the -6 dBFS white noise file from AudioCheck and I was using the DeltaWave comparator and it resulted the above audio spectrum differences. We can see that below 14.6 kHz the differences are extremely low, but above 14.6 kHz these are increasing (probably the microdetails some of us seem to hear?!?).
Some textual differences between V6 Vivid vs. V7 Vivid are below:
When two audio files are identical then the rms difference is -400dB, but in our case the difference is -80dB, so as per above the V6 and V7 sound files are different. If this tiny difference is audible or not is up to the golden ears to tell us or perhaps to a well conducted A/B test. Since then, my ears are inclined to like the sound of 2 x V7 Vivid + 1 x V7 Classic in my Soloist GT 2023 headphones amplifier.
- Gain= -0.0014dB (0.9998x) DC=0 Phase offset=58.232606ms (2795.165 samples)
- Difference (rms) = -80.45dB [-91.99dBA]
- Correlated Null Depth=92.33dB [99.08dBA]
- Clock drift: -0.07 ppm
I’d have to remove the window from my B4-X case in order to fit them in, but that would just be wrong, so it won’t be me that does it.Currently wondering how long it'll take before someone pops a set of these into a little bear b4x
Too early to provide a definitive answer yet, mostly because I had not enough time to blind test it. However, as per initial impressions, I find that the 4 x V7 Pro Vivid + 2 x V7 Pro Classic combination is being the more musical one. I'm eager to read other's impressions about this combination, but I still need to wait for the market to open for this product.
Correct me if i am wrong the only difference is slight improvement in micro details? From v6 to v7?
