Hi,
monoethylene
Thanks for the fast reply, I am new to the amp world, so I am so confused with choosing my first amp.
Does an amp with all headphones?
>> Objectively I would say yes, regarding only the technical side (if you are not using an exotic one or an electrostatic one) but subjectively there are different amps which play better with certain headphones. Further different designs maybe used to amplify the analog signal and so on. This is really a long long story and every person has another preference..
Does the amp work for computer only, I mean if I purchase a decent cd player later, can I still use the amp?
>> The Cantate.2 in detail also has one RCA input. This means you can use the DAC of your CD player and go into the amp. I dont want to confuse you. In general or with other words an D/A converter can be seen as an (external) soundcard with the aim to provide an analog signal. In most of the cases this "D/A-chip" is superior to the onboard sound of the computer. To connect this D/A converter usb, toslink or spdif are possible. As a conclusion and with some "tweaks" at your computer, you can bypass the whole sampling and converting process of your computer and the digital signal is passed to the D/A converter. There it is converted
and the analog signal goes to your amp (amp and DAC can be in one enclosure or not)
what amp is the most recommended for hd650?
>> Really I dont know and I never would state an opinion to a question like this
what about sound card, is ASUS Xonar Essence STX the primary choice for most users?
>> I ve read about this card a few good reviews and was a step away to buy her. IMO I think you cannot go wrong and perhaps all your needs are satisfied with this card at the moment.
Asus claims they have built in amp, is it true?
>> Yes.
or should I go with a different sound card?
>> The Asus is a good choice but also an expensive one IMO. I have a ESI Juli@ and I am happy eventhough I am using this card in general to record things.. Regarding stereo music and hearing at all I think that the ASUS is a very good choice but Soundcards are not really my subject..
