Hi. I need sone advice. I currently use senn hd555 for hone and just bought a pair of onkyo fc300 (which i love). Have been usjng a 7th gen classic with alacs. And have been happy. Today installed annold pioneer receiver and a cd player. Same song soynded completely different on the senns. Like wow nice. I don't get it is it the amp? The dac? Alac should be same as cd right? So... Ahould i get something like a nuforce iDo. Would i get the same sound? Thanks all!!

Please proof read what you write before posting.

ALAC should sound about the same as an audio-cd.

 

So the Senns sounds better then the Onkyos? or the Onkyos sound better then the Senns?

Do they sound better when used with the 7th gen (something?) or the old Pionner?

What model CD player is it?

How is the CD player connected to the Pioneer?

Senns sound better connected to the receiver than to the ipod. The cd player is actually a bluray player connected to the pioner through stereo cables (red and white). I am on a bit of budget and decided to use what was at hand at home.

The bold made laugh, for some reason I had a picture of an old deadpan guy saying this.

 

To answer your question, its really hard to identify what is making it sound better as it could be a combination of both. A quality DAC easily affects the entire sound quality, adding detail, and can add/remove warmth. An amp similarly can do the same thing and the ipod has neither a good internal amp or dac imo. Its a good thing you are using full quality music however that only removes one factor of many in an headphone set up. That is why you see people spending thousands of dollars on their rigs. It is hard to say what would give you a bigger improvement. However if you are trying to use a direct digital out of your ipod, I think the cheapest dac that allows that is $300.

Ouch! I was trying to avoid that. Was readong about the nuforce iDo. It is supoused to work as a Dac/amp. How good a dac well... Not sure. But probably better than the ipod.
Would use it at home only. With the senns hd555.

Guess the Pioneer is output more juice to the headphone then the iPod.

My HD558 does sound good plugged into my Yamaha RX-V671 receiver.

You might consider putting a DAC between the Bly-ray player and the Pioneer.

What model Blu-ray player is it?

This doesn't surprise me. Look at the impedance curve for the Sennheiser HD555:



The ipod probably just doesn't have enough juice to handle that big bump in load at around 80 Hz. The receiver probably just breezes right through that.

I find that a tad shocking everyone says that hd555 are pretty easy to drive. Go figure! So i guess a nice amp would really help the ipod then. Right?

It's a sony BDP-S490. I though of the dac but the truth is almost all my cd have been ripped to alac. Plus songs i've bought online. And all my music lives in the ipod. So was really hoping i could use it as a source.
