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.

Thanks so much. 

 

Im a bit of a noob when it comes to the technicalities of all this stuff, so your post was insightful. 

 

In regards to your suggestions, I have a follow up question. 

 

The majority of my listening is not through the turntable, but just normal computer audio (music, games, movies, etc.) Recently I have been looking at getting a relatively budget DAC/amp combo (e.g. the audio engine d1 or fiio e10k), for better sound quality and the potential for driving higher impedance cans. 

 

However now the turntable has thrown a spanner in the works. Is it possible to buy a budget DAC/amp with a line in component (like that on the back of my computer) which would allow me to listen to the turntable through headphones when I feel like doing that? From my research it seems that the fiio E10k does not have this line in port. 

 

I guess id just rather not buy a dac/amp for my computer, as well as a separate amp for my turntable.

I used to run my headphones to my Aune T1 DAC amp. It has USB as well as RCA inputs I used it to connect to both my computer and my turntable. It also does have an RCA output for powered speakers or external amplifiers, but it only works for USB and not RCA in.

 

If you're planning to only use it for your headphones, the Aune T1 will be an excellent component.

My speaker system actually plugs connects by 3.5mm rather than RCA, so if i wanted to listen to the turntable over speakers rather than headphones i think I could just swap out my heaphones for the speakers and it would work fine.  

 

In regards to the speakers (jamo i300) though, they are peculiar in that they have an D-class amp inbuilt into the subwoofer. This is why I was always able to listen to my turntable with them, without a stand-alone amp.

 

Would connecting an amp/DAC to these speakers be ill advised? (is double amplification a thing?). 

 

E.g. If I bought a DAC/amp, the chain would be; turntable or PC --> DAC/amp --> speakers(inbuilt amp). So there would be two amplifiers in play.

It all boils down to your choice. I am eyeing ( because of necessity to play DSD files up to DSD256, for computer at home and Android on the go ) Xduoo XD-05 - as it also has line input, required for dynamic headphone listening to analogue sources, be it turntable or monitoring of live music recording. The lowest price I have found is on Gearbest ( approx $160 with shipping + any import duties, sometimes same/similar price is on ebay ) . There are decent amp only solutions in the http://www.head-fi.org/t/684159/chinese-asian-brand-info-thread-headphones-iems-amps-dacs  and elsewhere - it all depends on your desires and your wallet.

That dac/amp looks pretty neat. It looks like it has an input switch which would come in handy for a pc via USB and turntable via line in combo.

Price isnt bad either. Do you reckon the sound quality/amp strength would be suitable for high impedance headphones like the seinheisser hd650s? I'm in the market for them but I have never used headphones with such high impedance headphones.

Yes, XD-05 is suitable for high impedance cans, as it runs off + - 9V supply, enabling enough voltage swing required.. It also has its own thread here on head-fi - please check it out for partnering with relatively warm sounding HD-650s, as it in itself has similar signature. 

 

You ( along some 20k other souls...) have just missed Massdrop*s Sennheiser HD-6xx drop - which are nothing but HD-650s with different cable/connectors and different colour - for 200 $. Hopefully, this drop will return...

Double amping is generally frowned upon because headphone out can provide more power than required by the amplifier inside the speakers. It wouldn't cause much problems if you take care not to turn up the volume.

Don't worry about the connection type, you can find converter cables to plug into RCA or 1/4" jacks.

 

I do have several components in my setup - turntable, computer DAC, CD player, so I have an input switcher to switch between the components. 

 

What you'll need is a DAC amp with pre-out functions. I'm still thinking what is suitable to suggest to you as some solutions might be either expensive or separates.

That drop was what got me thinking about my audio set up again. I decided that if it comes back I'm going to jump on it (but my economically trained brain tells me the price will be more than 200 next time round...)

Well, I fear you are right - which means , IF I ever decide to go HD-650 route, I will have to get them here in Europe. Shipping + duties will probably be deal breakers - I have seen price of approx 320 EUR for HD-650, which would have made the point of going Massdrop in case of >200$ price moot.
