I recently had my Hermes modified by Jerry at Audio Magic. There is no mistaking the wonderful improvements as a result of his fine work. The unit was already extremely good (stock) but the mods further improved image focus /3D imaging and layering, bass articulation and tonal differentiation (in the bass), increased soundstage depth, elimination of midrange glare (except where the software is to blame---good recordings become excellent and excellent recordings are unbelievable), crystaline highs, and excellent dynamics. Jerry's quick turnaround and excellent communication were also greatly appreciated. This work is truly a bargain. I must also mention that my unit "only" has 60 hours on it and continues to improve daily (mostly due to the cap forming). All I can say is that Kora produced a fabulous product (stock) and with the mods it is superb!! Highly recommended and a true value without compromise. This may be the best digital at any price!
Hotrod your Hermes
I've owned the new 24/192 Kora Hermes for several months now. Right after I got it, I commented on one of the threads about the excellent performance of this DAC, especially at it's price point. I promised to provide a more thorough review of this DAC after it had some time on it. Unfortunately, I failed to do this. Reason being, I began modifications on this unit after observing the open architecture inside it. Since then, I have done the following:
1. Replaced the stock tubes with Seimans gold pins (Be careful doing this. The current Hermes has pin type tube sockets with springs inside them. Lose a spring, and your tube won't make contact. No warnings in the manual about this. This happened to me. Luckily, JC Audio exchanged my "missing springs" DAC for a brand new one. Great customer service!! In the future, Kora plans to change these sockets)
2. Top Hat tube dampers
3. Audio Magic 99.999 silver wire on all inputs and outputs
4. Shakti on-lines on the circuit board
5. Shielded the two transformers from each other and the circuit board using non-magnetic MU metal
6. Replaced all caps with a mixture of MIT, Hovland, and high precision oil caps
7. Shakti stone on the transformers
8. Replaced input and output jacks with WBTs
This turned this already excellent DAC into....A MONSTER!! Why? There is only one way to describe the performance of the Hotrod Hermes. IT'S ALIVE!!! The silence of the background is stunning. The images are more palpable and more full bodied. The soundstage is deeper and wider. The background is blacker, and details you never believed were on redbook CDs are now clearly audible. Yet this DAC remains extremely musical. This is by far and away the best DAC I've heard. Not an analytical bone in it's body. A friend of mine also modified his this way, and will add to this thread about his impressions. Jerry Ramsey of Audio Magic suggested many of these mods, and did the serious ones. He does excellent work if you need someone to do it for you. If you own a Hermes, you must consider doing all or some of these things. The potential to make an already excellent DAC into a world beater is huge with this thing. And the cost of the DAC and mods keeps you under $2500.
