But of context for my question;
I recently started using my turntable again after a few years. My turntable (dennon 297) has an inbuilt phono preamp, and I used to just connect it to a Jamo i300 speaker system via an RCA to 3.5mm adapter, which had an amp integrated into the subwoofer.
What i wanted to do was listen to the turntable with my headphones (bowers and Wilkins p7). However, I do not have have a headphone amp.
I thought I was out of luck until i connected the turntable to the line in(?) port on the back of my desktop. Sure enough, plugging headphones into the headphone jackon the front of my desktop allowed me to listen to the turntable. The computer volume was only 30% at my optimal loudness level.
My questions are;
Does anyone else use this set up, and are there any obvious flaws with it? Should i just get an amp instead of routing through my computer? Everywhere I have looked Im seeing that it is pretty much necessary to use an amp when using a turntable.
I'm thinking it might only be working okay because my headphones are low (40 ohm) impedance?
Thanks for any help and suggestions
Since your TT does have inbuilt phono preamp, it outputs RIAA equalized line level signal - just what you need for your line input of your desktop computer. So far, so good.
However, computers are notoriously noisy environment for audio and unless yours is specially configured for audio ( very quiet power supply, high quality sound card , actual line in input WITHOUT AtoD and DtoA conversion) , you would most likely be better off with a dedicated headphone amp. It is up to you to decide, besides being compatible with and powerful enough for your headphones, whether this should also be portable or not, whether it should include DAC or not - because the posibilites are almost countless. From inexpensive ( but quite good ) chinese little amps to something like Astell & Kern devices.
