I have just taken delivery of my HD800s and balanced cables. This is the rig I have set up now is as follows:
Source: Macbook Pro running Decibel with Apple lossless files. Optical out to a Balanced DAC LITE 83.
Amp: Balanced LD MKVIIISE with Electro Harmonix Power Valves 6H30PI and PSVANE 12AT7s Driver valves
Cans: HD800s with Headphone Lounge balanced cable
This rig is delivering detail I have not heard in my recordings before, the imaging is very holographic, like I am in front of the performers. The tone is sweet with the top end harshness of the HD800s nicely tamed by the valves. I would go so far as to say that the sound is very analogue, yet there is so much detail.
The PSVANEs are also amazing... once I took out the stock Electro Harmonix driver tubes and put these in the clarity and realism took a step up! Compared to my balanced Headroom Amp, the LD has really taken the level of detail, realism and imaging to a new level.
I am totally blown away with what I am hearing with this rig... I am discovering my music collection all over again. The LD VIIISE is performing way above my expectations, especially with the currently installed valves.
