I would have recommended the TA-100 in place of your Yamaha AVR, and it's too bad you got the headphone amp as I have two brand new in the box Nuforce HA-200 Class A amps for sale  Chad What do you think of the PT-100 + A-100 in place of the AVR and Lyr? |

You would have more power for the headphones at a higher cost, though I'm not sure those Sennheiser's would need that kind of power, my buddy has the HD600's and Massdrop HD6XX and he has the Schiit Asgard 2 and Valhalla 2 with good results. I have those two Nuforce HA-200 amps for sale and I may keep one but I'm still only running a pair of Shure SRH440's which for the price sound amazing and they barely need any power as even the Fulla 2 I have can drive them fine, though I am eyeing a pair of Shure SRH1840 cans on Canuck Audio Mart Chad |

The AVR is new and I could return it ($500+) and the Lyr is easy to resell for around $350. Those emotiva setup would run me a little over $500 total. On another note, does anyone play music through their iPhones or iPads with a PT-100? Does the USB work to play music off a mobile device? |

The USB input on the PT-100 is a standard USB input, like you would find on a USB DAC. It accepts Stereo PCM USB audio up to 24/96k from any device that is willing to output it. The limitations really depend on the source device. 1) Any computer, including Windows, Apple, and most Linux computers, will send audio directly to the PT-100 (they'll see it as "an external USB sound card"). 2) Many phones, including most newer Android phones, have a standard USB output which supports audio. They will also work - but you might need a specific adapter wire. 3) The basic problem with Apple devices is that most of them are "locked" in such a way that they will ONLY provide a digital audio output to other Apple brand devices. In order to use an iPhone with the PT-100, you would need something that the phone will connect to that will then put out a standard USB audio output. For older iPhones, an "Apple USB to Camera Adapter" should work. For new iPhones, you would want the "Apple Lightning To USB Camera Adapter". (This is basically an adapter to let the iPhone work with standard non-Apple USB devices.) (They call it a "camera adapter" because the most common use for it is to connect a USB camera - but it will work fine for audio.) There are also third party "iPhone docks" that connect to the iPhone and send a digital output (Coax of Toslink) to the PT-100 or other audio device. (Make sure that, whichever one you get, it has the proper connector to fit your model of iPhone... different models are different.) You would need to purchase the BTM-1 bluetooth stick from Emotiva as it doesn't come with any of the preamps. I hate Bluetooth. Is there no wired way to do it? |

I don't know WHY you'd want such a connection from an iPhone to a stereo. Most persons have a phone full of marginal quality MP-3 files. ALL my MP-3 are MP3-160, a slightly higher sample rate taking more drive space for a marginal increase in SQ.
Years ago, you could get a WADIA device to play the digital files from an iPhone. I don't know if it is available any more. You might as well use the headphone output / splitter, to a high level input.
If you really are set on using the USB input? Get some kind of server computer. I use an old iMac and iTunes with ALL my files dual saved as MP3-160 and as ALAC. A MacMini might work well, be compact and still full-function.
Start by putting ALL your CDs on the confuser as ALAC or FLAC. That's what I do, than copy as MP3 for iPhone use.
I wish I knew where to get 24/192 files.

There are many places to get non-crappy quality audio files. Spotify and Apple Music high quality are 320 kbps files. I’ve also got a bunch of my CDs ripped and stored at that quality on my device. Why use my phone to play music? Because it’s got the best interface to browse of any of my options to play music. I have an Apple TV and it could play music no problem but I far prefer touching my display to any abstracted control device. That said, if I start to go lossless like ALAC or FLAC, I will look into a silent HTPC and put up with the poorer interface for the higher quality. |

I use my iPhone and years ago my iPod Touch both with the 'remote' app.
The app connects wirelessly to my computer which is connected by USB to my DAC. No loss of quality using 'Lossless' files.
If all you have is 320kbps files, I don't know why you'd want a digital connection. Or rather need a digital connection. The 320k is a good compromise between ultimate fidelity and smaller file size.
In tests on my old iMac (a 2009) using Grado SR80e on-ear headphones my volunteers could 100% tell the difference between MP3-160 files and ALAC. The preference was always for the ALAC.
Bitrate for ALAC is variable. And ranges from maybe 500kbps to 1100kbps or greater. I made up a playlist of 'duplicate' files which were NOT identified and had the same title. I left the room during testing.
To start the ball rolling, I turn on my DAC and select the USB input. DAC has no remote!
From my easy chair, I select the correct input on my preamp and start the 'Remote' app.
At shows, I've seen plenty of 'touch pad' systems with nothing but Hi-Rez files, all easily selectable by touch from across the room. Memory is cheap enough that I wouldn't worry too much about large files.
I don't know how much noise a Mac Mini makes, but I'm not sold on that approach. My older iMac works fine. I have 'fan control' installed and can turn fans down were they to seem too loud.

Headphone out to RCA 'splitter' to hi level input? I did that for a while to test, and still have the 10 foot cord around here. My pre amp has a front-panel 3.5mm input for such use, and some additional gain cranked into the circuit. www.parasound.com/p5.phplook at the 'features' list and it's 2nd from bottom. It's just my Opinion, but using a digital connection for Any flavor of MP3 is not necessary. I also use the phone when in the wife's car. Hooks up wirelessly and provides hours of non-duplicate music. I could drive cross-country and never hear the same tune twice. |

It’s a reasonable thought but I would prefer to keep my tv off when listening to music. Using the optical output from the tv to the amp only works when the tv is on (at least that’s how my tv is). |

You're still stuck with whatever format you did the transfer to the iPhone using. Typically, an MP3 of one flavor or another.
The MPEG-1 type can go to 320bps and sample rate from 32k to 48k. The highest frequency reproduced will be <1/2 the sample frequency minus a guard band.
I don't know offhand how to 'force' the encoder to a higher frequency. Most TV audio, for example, is 32k which is actually not quite as good a a proper FM Radio signal.
At least, that's off my small dish.
If you are willing to try an experiment, try saving some ALAC files to the phone and try THAT thru airplay. But in this day and age I see No reason whatsoever for MP3.
I just looked at iTunes Preferences. For recording a disc to my music file, I can choose mp3 to 192kb. And I can choose from 32k to 48k along with a few other options.
You can even opt for 'variable bit rate' which I'd guess means that 'simple' music runs at a slow rate while complex music has a higher bitrate.
