What I've been doing this week. 

 


I must say it's been tiresome and rewarding at the same time juggling through these 5 amps. 

 

I can imagine!

 It's far to complicated to go into comparisons, lets just say I ended up choosing JDS C421 (OP2227) as my new portable amplifier. I find it gives be some fairly awesome synergy with my Etymotic ER4S, I would take the amp simply for that reason alone. 

 

I'll have to learn more about the JDS C421. I see that it is discontinued now. Hmm. I did find one on amazon.com for $232. More than I would want to pay, but then again, if I just stick around head-fi for another month, I'm sure that I will then be thinking that it's a bargain!

Damn you! :)

 

Any feel for how it sounds with the C3?

Yup, sounds great. :)

You need to remember though C421 has rather high output impedance (around 10 ohms) which can cause problems with some multi balanced armature IEM's. My TF10 and Rhapsodio RDB V1 Mini are fine with C421, the 10 ohm Dunu not so much, I experienced problems. Like I mentioned last page, the amp was worth it just for my ER4S pairing and full size headphones.

Ok, got it. Thanks!

So I see something interesting there also :)

Yeah the x2 9v batterys arrived. I really don't hear what the fuss is with that amp.

Not doing me any favours. I honestly prefer the sources headphone out compared.

Could be the new "S" is that much better? or you need to talk to it nicely.

 Big gamble on that, since it would be roughly the same as a C&C XO2 ( to keep it sort of on-topic ).

I honestly prefer BH over that Panda Audio amp. So not sure what to say.

That would be enough to say  :)

I love the C&C BH2!

I pair it with my DX50.

Sweet with my A900x also M50&HD650 the two outs are cool a nice change.

I remember some fairly serious bass coming out of that combination.
post #3088 of 3289

Yes plenty of bass.

It's wonderful with the DX50.

It's a bad little amp!

Do anyone have both BH-2 and C5?

If so what's the difference?

I wrote something about that here.

Does anyone have a graph of the output with no filters, and one with the LF switch on?

I love the sound that the LF switch gives and would like to try to EQ similarly when im using my Dx50 without the BH2.

I know it boosts bass and trebble (basically 'loud' on a car stero) but im specifically looking for a graphed curve with how many dB of boost at what frequencies. I've tried various smiley shaped EQ curves, but cant get quite the same sound as the LF switch.

Overall im very happy with this little puppy. a good value for the money.

Thanks
