I'm thinking maybe its swinging a decent amount of voltage despite its relatively low power output? That seems like something that might work well for a lot of Beyer cans...

 

 

Would be interesting to see how it flare wtih your LakePeople amp. Keep us informed.

A20 is no match for the V200 amp here, but the A20 does play nice with the T70 and T90

I'll definitely let you know. I'm still mulling this over but I'm pretty sure I'll be buying the A20. I need a second SS amp so that I've got separate volume control for when multiple people are listening and the A20 sounds like the perfect companion because its kind of the exact opposite of the G109; the G109 is low output impedance with lots of power and the A20 is high output impedance with relatively low power. It would also be nice to have a separate amp for my more sensitive cans so I can have plenty of usable volume range without having to open up the G109 and adjust its gain settings. And I love that the A20 has a parallel output. So far it looks like its exactly what I need unless it turns out to not work well with my mid/low impedance cans like the K712 and DT1350. And of course it doesn't hurt that I'm a big Beyer fan and have several of their cans that I'd love to try with the A20. ;)

I'm assuming you're referring to how powerful they are or are you saying the A 20 is sonically inferior?

Yes to both, and the difference is not small

Interesting. Have you tried the A20 with any lower impedance cans, say around 32 ~ 80 ohm? I'm wondering if the high output impedance will cause issues with those cans.

I have tried it with the COP, L2 and the DT770 AE, and even the LCD-2 ;) . With those to me it is just an ok amp, nothing exceptional.

The amp just isn't, and very logically so, up to the level of a 1K amp like the V200 or even V100 (which I sold)

 

To me you can clearly see/hear it was specifically tuned for the T70 and T90 / Beyers, but even for those there is a lot better. However the price/quality ratio for the amp is correct.

 

Beyer will also be releasing a new amp, an improved A1 if I'm not mistaken

That's very interesting, I should maybe wait to see what the A1's successor looks like.

 

Thanks, I appreciate it.

I recently tried the A20 with an TH-900 and was not that impressed. While the amp sounds very nice with the T70 or the T1 I tried before the Fostex it seems to be hindered by its high output impedance when driving the low-impedance TH-900.

I will jump all over this. Beyer T1 is a difficult phones to drive. And I don't want to get into tubes.

Of course this will be expensive
