USB DAC Digital AMP for Headphone

[oryaaaaa]

Hello

I am using custom Audiotrak DR.DAC2 and DENON AH-D5000. It cost $1,250.
DENON AH-D5000 sound than Senheiser HD-650. Most High quality Headphone in JAPAN.

DENON AH-D5000

The AH-D5000 has been designed for music lovers who want to enjoy a realistic sound in complete peace. The enclosures employ housings made of natural wood Mahogany with superior acoustic characteristics that are rich with a broad, natural sound. Mahogany is a very popular material for drum making and guitars because of its great integrity and capability to produce very dark, warm tones compared to other more common wood types like maple or birch. Along with its acoustic characteristics, mahogany's light weight makes it an excellent headphone material as well.
Microfiber has been used to form the diaphragm so that it faithfully reproduces the sonic details and delicate reverberations that occur in concert halls. The size of the Microfibers is approximately 1/100 that of natural cellulose used in ordinary diaphragms, and with this density, transmission rates are increased. In comparison, Microfiber diaphragms are (x20,000) and natural cellulose fiber diaphragms are (x150).
The Acoustic Optimizer provides optimum acoustic characteristics by adjusting the sound pressure balance in front of and behind the diaphragm. This makes the sound more dynamic, provides clear bass, and also keeps balance at low to mid frequency ranges.
The cable used is made of high purity 99.9% 7N OFC cable and employs an aluminum connector cover and a cloth mesh jacket. High-quality cables of equal length for the L/R channels are used to maintain optimum sound quality and performance.
Additionally the AH-D5000 headphones use a light-weight magnesium frame. This frame lets listeners enjoy maximum comfort during extended listening sessions.

My DR.DAC2 use High quality Audio capacity ( MUSE ) and High Quality OPAMP.

then

I use software AIMP3 ( Ru ). Select AsioKs, Select USB Device (coz iMac) Audio.
SampleRate 96kHz, 20ms ( Pass Kernel Mixer )

ASIOKS (Direct output WDM)

I want to M2TECH Hiface RCA for MacOSX and iMac.
Software Audirvana Plus, Super High Quality Sound. but expensive.
and Sometimes crush by MacOSX Audio Mixer (depend iTunes).
maybe, will connect by DSIX

I use a Fiio amp, and a pair of old Koss hv/1a headphones, plugged into the green 3.5mm jack..

There is a DAC built into your equipment already, and they are very good as is, no need for a
separate DAC in my opinion.

A few others worth considering:

My CD player (Marantz CD6002) as well as my amp (Sony STRDA1200ES) both have a decent DAC. Anyway, my headphones are too crappy to notice the difference

[oryaaaaa]

Everyone is wonderful.

In the software development of Japan, it is accepted to develop while listening to music with USB-DAC.

Best Audio products, It is an audio manufacturer in not Sony in Japan but South Korea that makes a state-of-the-art audio player in Asia.

The M2TECH Co. in Italy is famous in Japan. ($249)
USB output support 24bit/192kHz for Windows and MacOSX.
http://www.m2tech.biz/hiface.html

The latest audio player of South Korea is made by Android OS.
The improvement sampling is done to 192kHz of 24 bits. (Information before puts on the market)
Maker name "iBasso"
http://www.ibasso.com/en/home/

There is information that other manufacturers also are making it.

@USCode
It's expensive. really?

@utopiomania
It is sold also in Japan. But Sound is average. then not poplar in Japan.
Very cheap products. coz if it buys it directly from Hong Kong. (half price)

@blueznl
I recomend DENON AH-D5000.

@USCode

All the ones I suggested aren't inexpensive but are certainly no where near the top of the market and are all quality products.

iBasso products are good for portable sound but not quite up the the level of the desktop products I suggested above.

If you want portable sound, check these out as well:

DACs today, even the cheapest ones, are usually technically near perfect circuits, and
sound great.

Beeing cheap ones inside your laptop, or expensive external units, they are generally
equal in technical performance.

The Elephant in the room is the lack of a true clipping indicator in the analogue part of
your equipment, be that a serious power amp, or the analog amp section of your little
mobi.

You need serious headroom to avoid clipping, and to preserve fidelity of sound, hence
my Fiio hint, as I have no clipping indicator.. Brute Force.

If your analog section clips, it emits high freq noice, reduces dynamics, and cuts of micro
detail in the music, which sounds awful.

DACs today, even the cheapest ones, are usually technically near perfect circuits, and sound great.

Jitter rejection, analog circuit implementation, filters, etc. all can have an impact on the sound quality of a DAC ... which itself is a very subjective thing.

I changed OPAMP in DAC!
FDO, LineOut:LME49990 with browndog ( 2 circut )
Headphone:OPA627BP with browndog ( 2circut )

LME49990 is chosen to reference OPAMP in Japan.

Texas Instruments LME49990 Datasheet PDF
http://www.ti.com/lit/ds/snosb16b/snosb16b.pdf

A lot of people remodel to ready-made goods, and it changes it for LME49990.
me too

Ultra resolution, Realistic sounds, and very clear.
Do you use LME49990 OPAMP?

I will buy LME49990x2 with browndog in Japan, It's $10.
