I guess when we all have the chance to live with it for awhile, more will be revealed.
I think it's also partly a synergy issue, because the while the Slim also improved/increased the ES3X bass it did not give the UE11Pro or W3 a mid bass bump. Those definitly dont need one. The bass also improved after switching from iPhone 3GS/TWag to an iBasso D4 as DAC feeding the Slim.

Considering that these phones all have pretty similar impedances, it's surprising that the amp would give a mid-bass bump to one and not to the other.

Thread Starter 
I've noticed that my TF10s tend to have a lot more bass when plugged into an amp of any kind vs directly from an iPod. Also, different generations of iPod give them varying amounts of bass. It wouldn't surprise me if it were the same for other IEMs. It would certainly explain why portable amps are so popular, as a sudden bass boost is the quickest way to give the impression of an improvement in sound to the average person.

I agree with that, but one headphone plugged in different amps is not the same as multiple headphones plugged in one amp. The amp sees a load and transmits the amplified signal, but it doesn't know the difference between a UE11Pro or a ES3X. So it makes no sense when Larry says that the amp gives a bass boost to one of his IEMs but not to the other.

The proto pico slim I heard was just wonderful for IEMs and good enough for grados too. Its diminutive size is a credit to the design abilities of Justin.

For those of you that are getting your slim on Monday, could you please post some initial impressions for those of us that are still dripping or salivating? Even though the slim may not have burnt in, but initial impressions are always fun to read and know. We also like to know whether the sound changes over time or not? Does anyone know how long is the recommended burn in time?

Wanted to know also is whether the production model is any different from the demo version. Whether the memory for power on feature got retained from before? and do we know about gain settings? is it controlable via software setting? Looking forward to monday to hear from you guys.

I did not keep the setting that slowly increased the volume to the position of the knob at power-on. what was a reasonable delay with a sensitive IEM became an extremely long delay with a full size headphone. the gain changes as you turn the volume knob, it's a variable gain amplifier

Wow, Justin, is it a new features? It is definitly a new concept to me. It sound like it's similar to CVT (Continuous Variable Transmission) in car. I just love new technology whether they'll hold up over time or not, I like new thinking a nd new ways of doing things. Good job.

How long do you think the burn in time needs to be?

oh wow, does that mean that the volume control isnt attenuating the input at all? and is instead just changing the gain value? though that is all just hopeful speculation based on your comments

Let's give the burn-in stuff a rest for at least 7 minutes.
