Honestly some one needs to mod a pb2 to have adjustable gain on the Fly like the PB1 did, it's a shame you have to open it to adjust gain :/ 

 

still I also want a white one my self :D 

 

Yeah, that's the LCD-2 rev.1 on a PB2, balanced out.  

 

I leave the PB2 on Low Gain for the LCD-2, and I don't have any phones that need more power, so I never have to open the case just to change the gain, but I hear you - it would be nice if there were an external switch for gain.

I tape one side of the case, so it makes a hinge and use one screw in on the back of the case. Very fast and easy to open the case. I have rarely changed the gain though. 

 

What also helps with the DB-2 is that it used a battery for the digital section and one for the analog, giving you an even better SN ratio. It also gives you better dynamics and separation.

I have a 600 ohm dt 880 and a 23 ohm w1000x... you see my particular delima here lol

 

one likes HIGH gain the other likes SUPER LOW gain xD

I love the taped hinge idea, but then I'd be back to rolling op-amps 'til the wee hours of the morning, weekdays and evenings.  It's a wonder I haven't sealed my PB2 with Loc-Tite, just to keep myself out of it!  :D

$300 later I got a Pb2 with a LME 49990 set, in silver the color I wanted!

well I'm using the Dummy Buffers, as I do not need the additional power... or do i? 

 

No I don't. keeping it around for my D2k and W1000x, both of which do NOT need a lot of power!

And what do you think of the sound (with which DAC and headphones)?

post #1014 of 1293

I got this last night and I am pretty impressed.  I've had a set of hifiman headphones for a few months but nothing seemed to work well with them.  This amp made them sound really good.  

 

I see it came with all these different omp amps.  Do they all sound different?  I didn't see any guide telling me the different characteristics of them.  

 

Should have my alpha dog and audeze lcd-xc headphones next month.  Hope they sound even better.

I just paid for it today xD, shipped from China, it's in good condition I got extensive pics

 

and what do I think? well the only DAC it's going to be used with is the HM 801

 

btw, the LME 49990 are rather warm tbh, are there any... op amps that sound like the pb1? The hm801 is already thick warm and lush, I'd like really something like an LME 49720HA, something more on the SPEED and CLEAR side than warm. 

 

I had an LME 49990 in my Matrix M Stage and it sounded very good, but again the hm801 is already warm, I've got the HiFilight Top Kit and the entire Stock kit at my disposal

your the only person i have heard say the lme49990 is warm, the ive had the p4 warbler and the pb2 pelican and the lme49990 is to me, bright or maybe alot of clarity which makes it seems bright. and i find it to be very analytical, i dont find my pb2 to at all be warm. maybe its just me.

 

but you have to take into consideration the circuitry of the matrix m and maybe it made it sound warm?

IT could very well be just that :3

you might wanna try the LME49860NA it has a similar sound as the lme49990 but its a bit warmer in the IBASSO Amps...that is if you find the lme49990 to be analytical or bright.

 

 

i have a question for anyone.... what are your guys opinion on the DB2 BOOMSLANG using the upgrade LPF opamp.. i personally think it does add a bit of depth to the bass. just wondered what others thought.

WHOA NOOOOO

 

To bright is not in my Vocab, I drive a DT 880 with an Audio GD 10ES2, thats a bright amp and a bright can :D 

post #1020 of 1293

birds of a feather haha, i too like bright, but i think its more analytical than bright, or maybe its clarity that is perceieved as bright.

 

i have the er4s/er4p and the hf2 alot of people consider those iems bright but i find them perfectly detailed and accurate. warm signature imo withholds detail in the track, and thats not my taste.

 

i have cables like the Hybrid peptide symbiote silver plated copper cable for my se535, i also have the toxic cable silver poison for my westone w4r i have the toxic silver poison pure silver interconnects... have rsa male to hirose male toxic silver poison interconnect for the amp to dac....im into anything that is going to bring out max detail.

 

and now saying that i might be perceiving all that clarity,detail,brightness,analytical sound from all that silver......but i still think the LME49990+HA5002 is hands down the best combo, maybe the muse01 or muse02 might sounds better, but those cost a penny or 2, and im not opposed to spending the money i dont care, i just havent really heard alot about those opamps and if they will yeild what i am looking for, again i have tried a ton of opamps and the lme49990 just does it for me, but everyone is different.
