How well provided for is your other house? Good radio signal reception for FM/DAB? Fast & reliable internet?
If 'no' to both of those, then you are left with CD and plugging in an iPod/iPhone. (Or streaming from a NAS if you don't need gapless playback.)
If radio reception is good (but internet useless/non-existent), then stick up a decent roof aerial and buy an Arcam Solo-Mini.
If gapless is essential (and there is no CD collection at the second house), then a Denon Piccolo will probably suffice.
If the internet provision is great (and CDs, FM/DAB not required), then get a B&W A7 and plug the telly into the optical connection, your laptop into the USB and use AirPlay (with an appropriate iThing) for streaming from internet radio, iTunes, BBC Radio iPlayer etc. (Laptop via AirPlay too.)
I would think carefully about exactly what you want to use (and can use) at the other place and ensure that functionality/connectivity matches exactly with whatever you buy before worrying about quality. (No point in it sounding great if you need gapless, have no radio reception and the internet speed is lousy!)
I only mention all this because the traditional 'second home' is usually out in the sticks where reliable broadband is a fantasy and FM/TV/DAB etc. is often prevented by the local topography. Like much of Exmoor where we couldn't even get phone reception - on three different networks - a few years ago, and the surrounding hills prevented any radio. Broadband was something the locals had only read about (along with ATMs and paying by debit card!)
