Hello,

This will be my first post on these forums.  I've been able to budget this month and think it might finally be time to take the leap into hi fi.  I was hoping, if it is not too much trouble for some sage advice. 

I'll give you a quick run down of how I've been configuring my system (constructive criticism welcome)

Components

Amp: Technics SU 3000 integrated stereo amp circa 1973

Speakers: Tannoy Saturn S6LRC (on loan)

Source: Laptop (mp3 320kb/s or FLAC/WAV)

Sound Card: Novation NIO 2/4

So essentially laptop (VLC player) > usb 3.0 > nio > rca > amp

I'm not too sure if the Nio has a DAC in the signal path somewhere, I mostly got it for its recording and DJ application. 

ANYways back to the initial topic...

The first component I have considered for replacement is the amplifier, though the thing is in great shape, spent most of its life in storage.

Here are the specifications 

Now for the questions.  How do these spec's measure up to current mid range hi fi integrated stereo amps?  I've been looking at the Music Hall a15.2 and Cambridge Topaz am10. 

Do amp's degrade over time?  Does the fact that it is 40 years old make a huge difference?

Considering my configuration (and the fact that I am only filling a small bedroom/living room) is a new $500 amp worth the benefit?

I will also be looking into new speakers as the Tannoy's are just on loan at the moment, possibly the Epos Epics.

Is my configuration wack?  should I drop the Nio for a dedicated DAC?  is the Nio giving me any quality increase over my native sound card? 

Thanks for any advice you can offer!
