Tube or not to tube?


I am new to the hobby and would like some input. I am seriously considering moving to a tube-integrated amp (new or used)like the PrimaLuna II or the Jolida 502. Currently I have the NAD Combo 162/272. Would I be upgrading my system with either of the tubes? Or am I just moving sideways?

if I do try a tube amp like the Primaluna can I use my NAD 162 pre-amp? cd player and turntable connection.

I'm not sure I understand the question about being able to use your CD player and turntable connection.

You can certainly use your CD player with the Prologue 2, and if the Prologue 2 has the phono card, then you can use your turntable.

Since the Prologue 2 is an integrated amp, then you don't need to use your NAD preamp. Whether you can use it if you choose to use it is not a question I can answer. I suggest you look at the info on the Upscale Audio website.
Sorry, I was looking at the prmia and the joida and I did not see either had a phono input. Just a cd,tape, aux. I do have a nice collection of lp's (IMO), In my wed surfing I have come across tube imtergrated amps need a per-amp for phono so, If I come across a unit with just an aux input can I use my current pre-amp?
If I come across a unit with just an aux input can I
use my current pre-amp?

If you want to use your NAD preamp, then buy an amplifier, not an integrated amplifier.

The Prologue 2 integrated amplifier can be ordered with a phono stage.

This is pretty basic research. Easy and fast to do.
I recently worked in a high end store. The best results we found..is to use a tube preamp with a MOSFET solid state amp. Best of both worlds. Tube preamp tubes last alot longer than tube amp tubes by 3x or so, and they are much cheaper than amp tubes.
If I were you I would buy a nice tube pre..use it with your NAD amp (bipolar I believe). You will be blown away by the musicality-listenability. Then step up your amp to a MOSFET type, you will then be awash in tube-like sound. The bipolar amp will deliver tighter and stronger bass but the MOSFET amp will better duplicate tube like bass and distortion quality. However you want it.
Christobyl, That sounds intriguing, However I am new to the hi fi world and am a bit lost. If I may review with you:

Tube preamp (would need to purchase) Something like this? Rogue audio 66 Tube Preamp
NAD 272 amp (currently own)
MOSFET amp S.S. (would need to purchase) Something like this? Aes cary SET Ii single ended mosfet amp.

Again thanks for the input
