One of the best IEMs that I have heard in a long time, and my personal favourite going forward. Just be prepared to be stunned at its sonic performance and musicality. Highly recommended 9.9/10.

Welcome to my new video on how to upgrade the opamps in your device, in my case using the Burson Audio Playmate 2 Headphone AMP DAC.
In this review, I take a look at the Burson V6 Vivid and V6 Classic Opamps and compare the sound quality between them. Before we talk about the sound quality, I also show you how to install the new opamps. I also pick a winner based on my preferences, but highlight what each one would be best for. Burson Audio sell the V6 opamps for $145 for a pair.
Both the Burson V6 Vivid and V6 Classic make a terrific improvement to the sound quality of the device. Highly recommended 9.5/10.
Welcome to my review of the Burson Audio Playmate 2 which retails for £599. The Burson Audio Playmate 2 is a headphone AMP/DAC and Pre-AMP.

Two levels of power control, each with 100 volume steps. 110db IEM, no worries. 70db planar magnetic, no problem either.
MCPS charges the Playmate at 170 thousand times per second to enhance the power, dynamics and micro-details.
A decade ago, Burson Audio argued against using IC opamps on the audio signal path. Today, their discrete audio opamps are industry benchmarks. They focus on building great products that speak for themselves. Based on my experience so far, not only do they look stunning but they also sound terrific too! Plus with the added bonus of being able to easily upgrade the op amps, what more could you ask for!
The Playmate 2 has an easy to access and use menu system, that provides access to the following options.
Headphone level – High or Low, this is your headphone gain setting
FirFilter – you can select a digital filter that are built-in directly in the ESS Sabre DAC chip, there are 7 filters to play with
DPLL (DSD) – OFF, Low, Mid and High (default) – the higher this setting is the higher the jitter rejection will be for DSD files
DPLL (PCM) – Off, Low, Mid (default) or High – the same but for PCM files
Emphasis – Off (default), On – ON position rolls-off the treble by about 5db at 10 kHz and by about 8 db at 20 khz. Best to leave this setting to the OFF position. Only turn on if using a cassette tape player.
OLED Level – Low (default) or High – changes the brightness of the OLED screen
Reset Set: No or Yes – resets to factory settings.
