I've had the Sony MDR-MV1's since mid-October. Initially, I used a Sonic Unity Encore mDSD USB dongle DAC/amp that is based on an ESS DAC chip to drive the Sony's. I recently purchased an iFi hip-dac3 from Amazon. This DAC/amp is smaller than I expected. It has a smaller footprint than my iPhone 14 Plus, which makes it highly portable. So far, I am really enjoying this DAC/amp. Compared to the Encore mDSD USB dongle DAC/amp, this is smoother, more powerful, more detailed, and it presents a larger soundstage. The bass is deeper, more articulate, and punchy, and I am not using the hip-dac3's XBass feature. This amp provides greater headroom and doesn't have the mid-high sibilance that I heard with the Sonic Unity Encore mDSD DAC/amp.
The hip-dac3 came with a Lightning-to-USB-C OTG cable shown in the photograph. I did not know that this was included and was prepared to use the bulky Apple Lightning to USB Camera Adapter, so this was a welcome surprise. Had I known this was included, I would not have purchased a Linsoul DDHiFi MFI06L Lightning-to-USB-C OTG cable from Shenzhen Audio--oh well. For a headphone cable, I am currently using a single-ended Sony MUC-S12SM1 cable terminated at the amp end with a 3.5mm TRS connector. I ordered the balanced Sony MUC-S12SB1 cable (engineered with Kimber Kable) terminated at the amp end with a 4.4mm TRRS connector, so I can take advantage of the iFi hip-dac3's balanced output.
After a lot of research on portable personal hifi solutions, I settled on using the iFi hip-dac3 with my iPhone to drive my Sony MDR-MV1 headphones. I travel a lot for my job, and music listening is therapeutic for me, so it keeps me in a good mental state throughout the week. I had entertained getting a higher end Sony DAP like the Sony NW-ZX707 Walkman, but I try to travel as light as possible: one carry-on and my backpack, and my iPhone is a necessity, so then I focused on a DAC/amp. I was very close to pulling the trigger on a Chord Mojo 2 DAC/amp, but I kept running into videos and Web forum posts about the random white noise problems with iOS Lightning connections. Considering the cost of the Chord Mojo 2, I just thought I could risk damaging my Sony's and my ears. Then what? I looked into the iFi Gryphon DSD as an alternative, but it's a bit larger than I would prefer, so then I researched the iFi hip-dac3, and settled on that. I appreciate good, efficient industrial design, and the iFi hip-dac series of DAC/amps check that box for me. Besides, the hip-dac3's reasonable price leaves me with funds to invest in more music (love vinyl) and other audio toys like a nice Miter leather case to protect the hip-dac3.
Lastly, I am so pleased with these headphones. I love my Sony MDR-7506 studio monitors for what they are. Adding the Beyerdynamic EDT250V ear pads to the MDR-7506's made a huge improvement in sound quality, comfort and durability (stock pads disintegrated). I bought the MDR-MV1 headphones expecting to get something similar to the MDR-7506's, but with the openness and larger soundstage with the open back design. These headphones have not disappointed me at all allowing me to hear into the mix. The lightweight design and stock earpads are so comfortable, I can wear these headphones for hours without any discomfort.
I am now thinking about a good desktop headphone amp to drive these Sony's, and I am considering the Schiit Mjolnir 3 pure Class A headphone amp, but that could be overkill for a $400 pair of dynamic headphones. My current main system consists of the following:
- Bill Neumann (Fix My Dual) rebuilt Dual 1229 idler wheel-drive turntable with Shure V15 Type III MM cartridge
- Schiit Mani 2 phono stage preamp - single-ended connection
- Raspberry Pi4 running Volumio 3 USB-based streaming source
- Denafrips Pontus 2 R2R DAC - balanced connection
- Schiit Freya+ Tube/SS line stage with OS GE 6SN7's with side-getters (gain stage) and Tung Sol 6SN7's (driver stage) - balanced connection
- Pass DIY Aleph J Single-Ended Class A power amp - balanced connection
- KEF LS50 speakers
I really want to be able to tap into the main system for its excellent analog and digital sources. I am open to suggestions for a balanced desktop amp that is as musical as my hip-dac3 portable DAC/amp.
