There's a dedicated thread about V7 Pro op-amps, but you can also have a look to my measurements and thoughts when combining V7 Classic with Vivid.

Thanks for sharing, looks a very good hybrid opamp, though much higher in height than the hybrid Burson V5i, so it may not fit well in some designs. However, some head-fiers might still prefer discrete op-amps instead of hybrid ones, hence V6 and V7 remain a very good choice for audio devices...

By looking inside Violectric V380² I see that the transformer has 2x18 VAC outputs, so I assume that 2x18 VDC are powering the op-amps and the output stage too. Take care on overheating and maybe damaging those V6 and V7, given that V6 can't support voltages above 33V (+/-16.5V). Same about the...

I can assure you that Soloist 3X Grand Tourer is one of the fewest amps able to drive these cans to their full potential, so I totally recommend this amplifier to pair with ABYSS or with any other hard-to-drive pair of headphones. Now I'm listening to OSI since about an hour, it's past midnight...

There's an entire thread you might want to read about Playmate here: https://www.head-fi.org/threads/new-burson-playmate-9038-dac-2wpc-headamp-preamp-changeable-opamps.894619/. I/V would be the first op-amps you might want to swap, but still reading the above thread might help more.

might help, but please check also https://www.bursonaudio.com/wp-content/uploads/2020/07/Opamp-Install.jpg and https://www.circuits-diy.com/ne5532-dual-low-noise-op-amp-datasheet/#NE5532_Pinout too. I would suggest you to do exactly what Burson told you to. I suppose you might be better off to...

I would vote to a mix between the two V7 Pro models, Vivid + Classic, as I already mentioned here: https://www.head-fi.org/threads/burson-v7-classic-pro-and-v7-vivid-pro-hi-fi-audiophile-solid-state-op-amps.971554/post-17970369, but YMMV, of course. I see that there are some SO-8 soldered...

I might try adding some soft padding under the fan to see if the noise will decrease, but lowering fan speed is totally not recommended given that internal temperature can dramatically increase.

Voyager has a fan too, but its size, placement and the aerodynamics inside makes it virtually noiseless.

With all the upgrades you have done (5A Supercharger, V7 op-amps, SP2 modules) I think you're pretty close to it, so no worries about. :)

My Soloist 3X Grand Tourer 2023 Model was taking 74 Watts without any audio signal going in, as per https://www.head-fi.org/showcase/burson-audio-soloist-3x-grand-tourer.25668/reviews#review-31286. I haven't measured power consumption when driving low sensitivity cans, but I'm guessing that the...

If you have the original / default power supply use that one. A brief introduction about these Superchargers can be also read here: https://www.head-fi.org/threads/burson-supercharger-low-noise-power-supplies-24v-5a-24v-3a.971942/, but like @pokrog said already it could be the supply causing you...

I see people talking here about the SuperCharger and I felt that I needed to create a dedicated thread for this: https://www.head-fi.org/threads/burson-supercharger-low-noise-power-supplies-24v-5a-24v-3a.971942/. I really think that might worth adding your thoughts about this very low-noise...
