ALO Pan Am desktop/portable headphone amp/DAC: Impressions and Reviews - Page 23

post #331 of 806

received the Pan Am. Sounds great feed by the Algorthym Solo, not so good the MacBook Pro. I go into system preferences go into sounds select the ALO via usb as the output. I suspect this is an analog feed not a digital as the volume can be controlled on the MacBook. How do i get a digital feed to the Pan Am?

USB is digital, so you are good there...

Make sure your mac is not altering the feed in any way ( EQ, special effects, etc) also check for proper output sampling rate.
Max out the volume on the laptop and control it from the Pan Am

Oftentimes, analogue input resolves details better than USB input does. Why? Could be controller issues, could be computer noise. I would suggest using the Pan Am via battery and fed by analogue sources for best possible sound quality.

I recommend setting the volume control on iTunes to maximum to ensure you aren't potentially degrading the digital information.

Nawwww . . got to have some Mullard CV4010's and Russian tubes too!!

 

The Cifte's are great sounding tubes (I've had mine rolled in for awhile now).

 

Enjoy!

What are the sound characteristics of the CIFTE 5654?

I have settled on the Mullards, and really love them. There is something sweet and open in the mids that makes the sound very expansive. But, the bass is not as punchy as the Centrance Hi-Fi m8. While I am very happy with the Pan-Am/Mullards, (it edges out the HiFi M8 in overall quality), I would like to find tubes with a bit more punch if that is possible from the amp.

thanks

Just rolled in the Siemens. A bit bright as has been noted. however easy to tell that these will be the best of the 3 available from ALO.

I've tried the Astro Pro 10,000 (for short periods) with no apparent ill effects.  However, I mainly use the Passport battery.  The Anker is back-up power for various devices, including the Pan Am, DX100, etc.

It's OK to use a power supply that offers more Amps than what the load requires. 

 

It's not OK to use a power supply that offers a different voltage (or a voltage that's not polarized correctly at the connector).

Hello all just need some advice on my new Pan Am I got today. I have the Passport and Gateway connected correctly and I have a USB connection running at 96/24 in Windows 8.

 

Now my issue which I think is due to needing burn in time on the stock tubes, is that on the LCD-2 I notice that on songs with a lot of instruments/background music start to get slightly distorted. I understand that the Pan Am should have enough power to drive the LCD-2 at High Gian Volume on medium level.

 

I have a Schiit Lyr as well and the LCD-2 don't occur the same symptoms. Do you believe running pink noise for a certain amount of hours will resolve this?

 

Cheers.

post #345 of 806

Just a update, bit more burn in and its better. What I also found out is that I'm used to the amount of watts the Lyr outputs and treating the Pan Am that it can pump out that much juice. Putting the volume just below medium sounds fine for now.

 

Cheers.
