Little bear B4-X with Burson V5i Opamp upgrade

Opamp applied to: Little Bear B4-X Headphone: Hifiman HE4XX Pre- vs Post- opamp: High end tamed while maintaining most if not all of its dynamics. Instruments separation seems to be improved. Tonality remains somewhat the same which it’s a plus. In my case, the biggest improvement is when paired my upgraded B4-X with my iPhone […]

xDuoo, XD-05 Plus with Burson V5i Dual opamp upgrade

Massive difference in clarity and soundstage. The bass is much tighter and I can hear more of the nuances in the sound. The highs have more air to them as well.

Topping D30 DAC with Burson V5i Opamp

Install was easy. So far I am noticing improved separation, deeper mid-bass, and a high end sparkle that seems to be settling in as I listen. I feel the V5i has made an improvement.

Cambridge DacMagic 100 Burson V5i Opamp upgrade

The DacMagic 100 has a standard NE5532 installed. The sound is OK but somehow unspectacular. Somewhat difficult was the installation of the SOP8 to DIP8 adapter. After replacing the NE5532 with the V5i, the DacMagic is unrecognizable. The complete sound is more precise, more open. Instruments are better recognized. The sound stage is wider and […]

Bass hits harder and feels tighter. Not as distorted at higher volumes. Highs are more balanced and dont sound as harsh as they did with my DT 990 Pro’s.
Little Dot 1+ with Burson V5i opamp upgrade

The V5i is used in 2 devices. It brings all the finesse and dynamics for the DAC and also for the headphone amp. The bass is perfect, present and fast, without hiding the medium and highs. A real success.

Topping A30 with Burson V5i Opamp

Holy hell! The Topping A30 is a very nice sounding little headphone amp stock. It’s very neutral to slightly warm. But the upper registers can sound a little veiled. I read some reviews and several mentioned Opamp rolling with the Burson V5i opamps. Being a newbie to headphones, but not audio, I researched and decided […]

Zishan Z3 with Burson V5i dual opamp

Purchased this after reading reviews online, was originally eyeing the V6 classic but it was way over my budget. Wasn’t impressed with it upon installing it in my portable player but after the burn-in period, the sound i was hearing was beyond what my stock opamp sounded. Well worth it, i’ve been recommending this to […]
