Hello everyone, last week after many years I changed the speakers, after a lot of research, availability in Argentina and obviously prices, I bought Wharfedale 12.2 and I am very happy listening to them, I have a Polk Audio HTS10 subwoofer and I continue to adjust it as the days goes by, a Loxjie D30 DAC and a NAD 325 amplifier, I already ordered 12 gauge cables (do they need to be oxygen-free??). The seller tells me that the best upgrade would be to change the speakers (he seems like a good guy) but I've had them for 1 week!! I want to listen to them for a couple of years, so a possibility would be to give my beloved, beloved, NAD325 and approximately 800 USD to upgrade to a Marantz PM8005 made in Japan, is it worth the change? Or should I save more and buy another more powerful or higher end one? Thank you very much and greetings!
 
My handy-dandy spreadsheet says 70W is about 1.5dB louder than 50W. Noticeable, but probably not noticeable from one day to the next.

3dB is a power factor of 2.
6dB is a power factor of 4
10dB is a power factor of 10.

I already ordered 12 gauge cables (do they need to be oxygen-free??). No, but the wire should be copper (not copper clad aluminum). You probably don't need 12AWG unless you have long runs.

Wire resistance is proportional to the length and inversely proportional to the diameter. Lower resistance is better (relative to the speaker impedance). Here is a Wire Gauge Chart showing Ohms per 1000 feet and per kilometer.

Speakers (or headphones) DO make the biggest difference in "sound quality". Different speakers will ALWAYS make a difference (better or worse). Room acoustics make a difference too.
 
Enjoy your system, listen to music :)
One day, consider upgrading your speakers but don't worry about it now (not with such new speakers, you want to get used to them)

If you do want to experiment, get a umic measurement microphone and download the free REW software.
Make some measurements of your system in your room. That's the best thing you can do to understand your sound - where are the weak spots, what can you do to improve.

The umic and measurements will keep you busy, you'll learn and you will be ready to make the most of any future upgrades.

Thank! a lot for your answer, the web site I buy the wire canceled the order, I look in amazon and find this one, is less meters, I don't need more, and is more light son I pay less shipping.
The diferent materials and build quality is the Marantz does not enter in the equation? Sorry bad English!!

Sure, although you can probably find these locally too;
