Hi hum4god,
Thank you! I do have a few LIO trade-in units, and I received your email and responded this evening.
i am a little confused about the RVC + tubestage vs. the DHT stage . can they both be run at the same time or does the DHT replace the RVC + tube ?
The DHT PRE consists of the RVC (resistor volume control) + the DHT PRE module (which replaces the 6922-based Tubestage module).
i also could not find the price for DHT stage ?
The MSRP of the DHT PRE was $5995 (included the external power supply, new top panel, DHT PRE module, a pair of EH2A3 Gold grid tubes, and a few other items).
Regarding the different preamp options, this has been discussed in length in various posts in this forum. If I had more time available right now, I'd try to hunt through them to
give you links
Note:
- LIO was discontinued as of August 2019. I do have a handful of LIO trade-in units available (as well as new and trade-in modules). Please email me the configuration that you are looking
for and I'll try my best to respond within 24 hours, but it could be a little longer over the next few weeks because I am still very busy with new L2 orders.

I figured that things would have slowed down a bit by now, but it seems to be getting busier. With the upcoming reviews for the L2i and L2i-SE, I do not know what to expect.
I too cannot afford the newest and the upgrade bug is biting so I keep my fingers crossed for some way new or something new that will enhance my LIO. A more powerful amp mod would be nice or a re release of the VR120 amp would be kool.
Hi gene9p,
I think I mentioned this in one of the LIO threads a while back, but a more powerful amplifier module for LIO is not in the cards (I tried to make it happen a while back). It would require a new enclosure and new power supply design, along with the new amplifier design (and a new LIO Motherboard to accommodate all of this), and it would get very costly.
For LIO customers, I still offer modules (new and trade-in modules) so features and upgrades can still be had (including the L2 DAC and L2 Phonostage modules, which are compatible with a firmware update) - but there is only so much that can fit inside. There are internal space, heat and power supply considerations.
Stay healthy, everyone!
