A quick question if I may. I own Audeze LCD2F planar magnetic headphones and to my ears my Solo UL drives them as close to their full potential as any amp I've owned.
Contrary to popular belief, they are sensitive (70R / 101dB/mW SPL) and don't need close to the 1W-4W that Audeze used to recommend. Being planars the load is purely resistive. What they DO need to bloom is plenty of voltage, and I was curious as to whether the UL provides sufficient? What is the maximum V out of the jack? As I haven't managed to find any data online or on these fora I thought I might enquire here?

Max out is the IEC recommended 5 volts r.m.s., but the original UL uses output impedance correction feedback so I couldn't tell you what voltage will appear across 70 ohms without sticking the UL on the AP... but I don't have a UL.

And I'm not lending you mine...
At anything approaching 5V my eardrums would vaporise. So the short answer is "sufficient". |

I've no idea of the voltage requirements, but my UL drives Audeze LCD-2s to spectacular heights. And, incidentally my Novo/MrSpeakers Eon Flow Open is a super pairing too.

I have not yet come across a headphone that my Ultra Linear does not drive to its full potential, and I've used quite a few (see my signature). Output impedance correction feedback does what it's designed to do.
I would very much like to compare my pre 2012 non-DE to the current DE model, which has no impedance correction (yes, another shameless hint...)

The Solo UL can even drive the AKG K1000 fully, as long as the drivers aren't opened out fully. At open halfway, the upper areas of the Majestic and Solo dials provided full drive to my ears, compared adjacently to Majestic into Proprius and I couldn't hear a difference. Both sounded equally good for such a low efficiency and high impedance load.

Hi Graham and others,
I already have the lovely Solo UDLE and am planning to purchase a pair of Audeze LCD-3 which has the following power requirement: Impedance : 110 ohms Minimum power requirement >100mW Recommended power level >250mW Does UDLE have enough "juice" to push the Audeze LCD-3 to its max performance please. Would welcome any suggestions please
