Diky moc vsem.

V soucasne chvili hledam neco spise mobilniho, takze idealni by byl levny prenosny zesik ktery bych pripojil k transitovi. Do budoucna pozadavek mobility odpadne, takze pak bych zacal resit i nejake klidne i drazsi stacionarni reseni - a holt i napr. 2000Kc mi prijde (i s prihlednutim k cene sluchatek) za toto docasne reseni dost

K tem zvukovkam, dee nekde vyhrabal toto:
The audio cards’ line outputs work worse with the headphones: the crosstalk grows up considerably, and the frequency response changes greatly at low and high frequencies. Intermodulation distortions get higher, too. Thus, it is not correct to compare the audio cards when connecting the headphones directly to the line output because each of them responds differently to such a load.
To vysvetluje vse, holt nekterym zvukovkam nizkoimpendacni sluchatka sednou lepe nez jinym.

Premyslim ze bych se pokusil o tohle http://headwize.com/projects/showfil...=cmoy2_prj.htm
Akorat budu muset zjistit, kde bych sehnal potrebne operaky Burr-Brown OPA134.
