MY JOURNEY
Since late-2019, I’ve been slowly building my headphone setup around ZMF headphones. It all started when Tyler let me demo a few ZMF’s and I fell in love with the tuning. The Aeolus (b-stock Ziricote) was my first ZMF - a huge upgrade from the 58x (that I still have today, albeit now with ZMF pads). Since then I’ve continued with the focus of building “The Ultimate ZMF Listening Station”. I’ve reached a stage where I’m feeling pretty close to audio-nirvana.
Earlier this year I swapped the BF2/64 for the Yggy+ GS2/A1. Mind blown. While I loved the major leap in technicalities, I was not really happy with the leaner tilt, esp. with certain amp/headphone pairings. I bought the MIB upgrade card the day it was available. Just over 2 weeks now and I’m VERY happy with how this DAC is synergizing with ALL of my amps and headphones. I feel like the perfect balance has been achieved between technical performance and pure enjoyment.
LISTENING
I spend about 90% of my time listening to the Blue Halo+ amp. The Blue Halo+ was built by a talented amp designer/builder in Canada - @A2029. They design and build boutique amps under the moniker of 1101 Audio. I won’t go into all of the details of this amp now - perhaps one day I’ll get around to a more detailed write up (in the meantime here’s a brief product description).
My goal with this amp and working with @A2029 was to ensure that no expense was spared, either in the components used or the design of the circuit. Every decision was made with singular goal of ensuring the best possible performance with ZMF dynamics. This amp has taken a long time to get to know, but it’s been an extraordinarily rewarding experience. There are multiple configurations which can each run thousands (perhaps millions, with adapters) of tube combinations. Output impedance can range from ~6-8 ohm all the way upwards of 100 ohm - and anywhere in-between by running different tube combinations. Feel like ultimate high-fidelity, maximum clarity, and technical performance? Switch to “Blue Halo” output stage, enable CCS bias, and run extremely linear tubes. Feel like maximum warmth/decay/lushness (while still having a solid foundation of technicalities)? Switch to “Blue Halo+” output stage, turn on resistor bias, and run some higher distortion tubes. Or anywhere in-between…There are very few combinations I’ve heard that aren’t enjoyable, which makes tube rolling a continuous adventure. This amp can cater to any mood.
The Blue Halo+ has truly scaled up with better source gear. With the Yggy+ MIB, I believe the technical performance is at least par with the DSHA-3FN - if not exceeding it. The additional desirable qualities of tubes (more holographic staging, euphonic even-order harmonic distortion, etc) make the experience truly out of this world.
At risk of sounding hyperbolic, I truly believe this will be a Buy-It-For-Life headphone amp for my ZMF headphones (I made sure to get long-life caps that should last >30 years before needing to be replaced). I listen to it almost daily and it brings me immense joy.
The DSHA-3FN has become my “reference” SS amp. It’s simply awesome with all of my ZMF headphones. It happens to have IDENTICAL tonality to the Blue Halo+, with slightly more energetic edge and the typical things you’d expect from an SS amp. For almost every tube roll in the BH+, I’ll swap back to the DSHA-3FN as a reference to get a feel for how the tubes/amp config are influencing the sound. For quick sessions or when I don’t feel like firing up the tube amp, the DSHA-3FN never lets me down with any of the ZMF’s.
I rarely fire up the Bottlehead Crack, but I will never bring myself to get rid of it. Eventually I plan to set it up in a secondary listening station with the BHC + Aeolus. They will always be a matching pair as they both are made from Ziricote wood and finished with the same semi-gloss lacquer.
