Count one paying customer if you can do that! Wink

I shall be completely open to you, Graham: I see that there are headphone amps around from "other designers" that do wattages that are crazily higher than the Solo (albeit with the use of gain switches that you detest...). So high that I wonder if some crazy guy has accidentally blown some headphone drivers with all that power.

But I don't want amps from "other designers", because in 10 years of headphone (and phono stage) usage, I haven't heard anything better than YOUR designs.

The problem here is not your product, but simply a combination of low output MM and "quiet" LPs. The 140 mW that the Solo can do at 32 Ohms with an input of 511 mV RMS should be PLENTY to blow one's ears. The problems is that with such a combination of cartridge AND records, the input goes into a region of about 150-200 mV RMS which is obviously too low (although not because of your fault).

So I will patiently wait. And cost of the final product shall not be a problem. Smile

With sensible impedance load and lower gain/dial positions, a pair of Proprius monoblocks make a very capable headphone amplifier. Higher impedance loads recommended; in-ear devices not recommended. Start with lowest dial positions on everything and creep it up from there to prevent overdriving.

Yes, but wouldn't they be overkill, especially considering that all the headphones with a sound signature that I like are between 20 and 32 ohms?

Yeah, I wouldn't try with impedances that low, although it depends on sensitivity as well.

If anyone has an old Solo SRG and was in doubt about upgrading to the Ultra Linear, just make an experiment with ONE CD to be immediately won over: Massive Attack "Mezzanine".

The difference in the quality of the bass with this album is IMMENSE with the UL! I am in awe!
