Some say Lyr has more raw power. I dunno about Lyr, but I know that Pan Am cannot fully power my Alpha Dogs, i.e. at 3 o'clock I start hearing distortions with louder, bassier tunes, while this does not happen when I connect Alphas to Behringer (then I can actually loose hearing, and still no distortion).

I think it might have something to do with the tubes, however with Mullards this problem was bigger and with my current Sylvania it's lesser. The stock tubes were louder, and I am not sure about if they distorted or not. It could be that you can get better tubes for Lyr, and thus better SQ.

 Really? That's odd. Does this happen at high gain?
 
 From my experience, the Pan Am has more than enough power to drive both the HiFiMAN HE-500 and the Beyerdynamic T1, for example. And I always used medium gain when driving those headphones.

Nope, it happens at low gain, and volume set to 3 o'clock. I EQ lower end, but signal itself is not distorted, it's the Pan Am adding the distortion.

Also, at 3 o'clock Alpha Dogs are very loud, so maybe for some people it is too loud...

 Got it.
 I have never listened to the Pan Am with volume past 3 o'clock. I'll do it and post back in case I notice something weird.
 
 Did you try using medium or high gain and did you notice distortion around the same loudness (before 3 o'clock, of course)? Because maybe it is the pot? I know the RxMK3B+ doesn't seem to go louder after 3 in the pot.
 
 In any case I use an amp where I need to put the volume up to 3 I simply consider it's underpowered and turn the gain switch (if there is one). But that's me and I understand a good amp should be able to put out power from min to max of the volume pot.

is the pan am a pre-amp?

If I turn HI gain it starts distorting at 12 o'clock.

I finally pulled the trigger on the Pan Am, since ALO has a sale going on their site.
 
Got the Pan Am and the Passport for $500 and I can hardly wait to plug my LCD-2's into it next week.

Don't forget to change the stock Chinese tubes with others

And enjoy !!

really love this amp

 

[hardbop]

The only tubes that ALO had in stock were the French Radiotechnique.
 
Is there another source for compatible tubes handy?

 

[TontonJoK]

Ebay is the place to go

 

[TontonJoK]

I sent you a pm with a link, I didn't get mine from this seller, it has a very good reputation on ebay
The tubes are well matched and way better than stock Chinese

 

[hardbop]

Thanks!
 
I bought a couple others, too. Since this is my first tube rolling experience, might as well roll all the tubes.

 

[TontonJoK]

I saw the link is over now nice choice

 

[TontonJoK]

Sorry I made a mistake with the link I gave :eek:

You need a tube with 7 pins and I see 8 on the link I sent

If you can't cancel the order I will send you for free a pair of matched Mullard CV4010 I have in stock

So confused

I currently have Bose Companion 5's (which lets be honest are pretty awful) .  I also have some JH11's with a port rig.   If i buy the pan am for my laptop can i connect my IEMs to the 3.5mm, and by bose companions to the other output (and then line in on the speakers)??
 
Would there be an improvement in the sound qual of the bose speakers?
