In general it’s very similar in it’s driving needs to the LCD-2. It has a similar sensitivity and impedance. So, I threw my array of favourite portable amps at it. The first amp I tried with them was ALO’s Pan Am. It was a good pairing. Great sound stage, smooth mids and a bit recessed treble. But the LCD-2/LCD-3 is a much better match. The extra bass matches the Pan Am very well. And the amp started distorting after about 12 o’clock, no like. The best pairing I’ve yealded is the ALO Rx MkIII-B. Even via the Single-Ended output the bass, mids and treble is perfect. Fast and exact. Making the Pan Am feel sluggish. And running them balanced, all that is good gets a bit better. And the part I was getting to, regarding the bass… If you want that extra thick Audez’e bass, just turn the bass knob. Not too much. About 10-30% and the bass is almost identical in quality and quantity. Recommended. But for the non-electronic genres… The Rx gives more than enough. Portable, semi-closed and light. Check, check, check. Driving it with the Zana sounds great, but the HD800 sounds better. So for analytical, sitting in the sofa relaxing, it’s not my “final” headphone. I love that expansive sound stage and let’s face it. OTL and planar magnetics, not optimal. So why didn’t I borrow a _______ (e.g. Schiit Mjolnir, Cavalli Liquid Fire, EC Balancing Act) and give it a go? Well it’s pretty simple for me. Closed light headphones. Transportable audio for me. That was their purpose and that’s how they’ve been judged. So my comparision to EC ZDSE + HD-800 is slightly biased. However, you the reader might get even better results than I get from the Rx Mk-IIIB with some other amp. The rest is up to you, but please share!
Light. Well-built. Balanced sound. Sounds open but it’s closed. Quite easy to drive. It can get as pricy as you let it be, sound will be the same. And let’s finish with a rhetorical question. If LFF can make a 199 USD headphone sound like a thousand dollar(s) headphone, what could he do with a “better one”? Well for starters, without saying too much. The T50RP as a stock headphone is an unpolished gem. So there’s plenty of room to make the Paradox a very refined product . I honestly think that better isn’t possible from this “cheap” headhone. And secondly, maybe LFF indeed does have something planned using a larger driver. 😉 That’s all I can say at the moment…
