Cnet Review of the Pan Am is up!!

post #47 of 847

Has anyone compared the Pan Am to the Continental? I generally only use IEMs. I have Westone um3x/4 and I've recently ordered an Heir 8.A. I'm looking for an amp that is warm, but can handle output well at low volumes (<31ohm iems). I have a headphonia Headstage, which I love because of the bass boost. Any thoughts on the bass representation of the Pan Am or Continental?

However I also scored 100 or so of the exact NOS Telefunken tubes in that photo above also 6AK5s, they are out favorite in our shop test. I would be selling them now but we have not cryoed them yet. I have a cryo run commencing on Friday. The Telefunken tubes have a bit more gain and more resolution over all. I still like the Siemens as they are a little more laid back with really nice chewy low bass. 

 

Looking forward to the touchappz read.

Chewy? :)

Which tubes give the 'fullest' bass?

Looks like this 2.17 x 2.17 x 1.65 inches Linux box with the right cable could sit on top of The Pan Am with style

I read one review that says it can be a bit noisy with low impedance headphones.... 

 

Anyone else try this?  Is it just some tubes, or does it not work the best with low impedance?  Maybe if you use a 1/8" adaptor and plug a grado into the IEM socket...

I just ordered my Pan Am on Sunday, really looking forward to it. I've had my K702s on the market, all boxed up and ready to go, but I guess I'll have to swap the pads (new ones for the customer) and take a listen. I will compare the Pan Am with the Arcam rPAC and tell y'all what I think.

I bit on the sale price as well. Threw in a pair of Siemens tubes to mix things up. I'm very interested in hearing what this little guy has to offer. Should be on my doorstep by Thursday.

I received the Pan Am today. I'm currently using it with the Westone 4 until my Heir 8.A arrive, and there is no noise at all unless I crank the volume up past the halfway point, but listening level with the 31ohm W4 would not go much past 1/4. What is slightly more problematic is interference from computers. I am using an audioquest dragonfly DAC, and I have to stretch the 1/8 inch interconnect (2 feet)  as far as it will go to avoid cycle hum from the computer. I'll need to get a longer 1/8 cable for sure. The Pam Am also picks up ambient noise if it is touched, so it seems best to place it on a separate table or on a small peice of foam/dampening in order to avoid environmental sounds such as the vibrations from smacking my keyboard. I've only noticed these sounds when I'm not playing music. Once music is playing, the ambient noises are too quiet for me to hear, but I'd still like to avoid the vibrations.

 

I'm using the telefunken tubes, and right out of the box they sound fantastic. Bass has great impact and feels deep. I've never heard highs so well balanced on my W4s. They are a middy IEM, but feel much more extended with the Pan Am compared to the Headstage V3. I understand that tubes need time to burn in, but I'm in no way unsatisfied with the sound out of the box.

Please post your impressions if you're able. :)

I got my Pan Am + Gateway yesterday and spent the day playing with it. Cant give too many impressions as my 650s still havent arrived, so all I used it for was to drive my RE0s.

I dont have any experience with amps so I wont go into detail, but it definitely made the music louder, with possibly a touch of extra bass.
Again, I didnt use it with great headphones so I'll give my impressions once I get my 650s. I'll try to describe the sound with the Pan Am and without it.

This little thing is definitely the perfect fit for my setup next to my bed. If I primarily listed at a desk I possibly would have went with something larger, but for this particular setup, this thing is basically perfect.

It definitely does move around a bit since its so light, with the Cryo power cord included with the Gateway that is. Using the cheapo cable its possible that it'd move less. Not a huge deal as I have it set on a soft surface. And unless I deliberately move the cable, the amp doesnt move.

So yeh, I'll try to post impressions in a few days. I get my 650s tomorrow.

I received my Pan Am today in the mail. Nothing better coming home from a long day at school and practice than a big package for you. In this case, it wasn't an especially large package at all. In fact, it was quite underwhelming. After clawing my way through FedEx's packaging material (the best, in my opinion), I saw two black boxes. One was labeled "The Pan Am," the other one "The Accessory." Included in my Accessory box were a pair of Siemens tubes. I had never used tubes before, so putting them into the Pan Am was a new experience for me. They look so awesome :D

 

Next, build quality. I'm a stereo guy and have most of my audio budget directed towards it. So I'm used to extremely solid builds that look great (in my collection, at least). The Pan Am was a bit lighter than expected, yet still a very solid piece of equipment. I don't have the issue with the Pan Am sliding around my desk because of cables. This may be because I do not believe in using $400 heated and silver plated USB cables, but that's just me. devil_face.gif

 

My previous amps are the Fiio E11, Arcam rPAC, and the amp built in to my Pioneer Elite receiver. My "audiophile" full sized headphone inventory is limited to the AKG K702, though I have spent much time with the HD600s. I had a pair of RE-262s, but I think I may have lost those (left em on the school bus...crap). I've had the opportunity to briefly test out other amps too, and this is possibly the best I've heard my AKGs. Their often criticized anemic bass of the K702s was suddenly transformed into the deep, fast, and almost punchy bass I'm enjoying right now. The treble has lost a great deal of its graininess and harshness, and seems to have been tamed. Really, much like the HD560 (with which I am replacing the K702s), the K702s' main criticisms are easily solved by great amping. I personally was a non-believer, but now...I've seen the light. 

 

I'd really like to share more, but I have to cram for a chemistry and history test tomorrow. Thanks for reading-I'll definitely have more detailed impressions up soonish.

You notice extra bass? Which tubes are you using? I find a substantial drop in bass overall with both the Telefunken & Stock tubes. The Pan Am is well balanced, but on A/B tests between the Pan Am and the Dragonfly DAC, bass has far less punch with the Pan Am.

Really? I just had the opportunity to try out my friend's Dragonfly and I thought there to be better bass impact with the Pan Am-but this may be because of my tubes (I used the Siemens ones you can order as an option from ALO. I think for the size and price, the Dragonfly IS better. But as for overall audio quality, the Pan Am was clearly better. And it's not THAT big.

Are you guys talking about the dragonfly dac/amp by itself or just the dac section of the dragonfly feeding another amp?
