Buying new pre-amp

I'm currently still using my 37 year old Crown IC-150. I was wondering if I will hear any tonal quality improvements if I moved up to a modern pre-amp such as an Emotiva RSP-2. This is the unit I have my eyes on. I know S/N ratios will probably be much better, but will it sound any better through say the CD input which is basically a straight through connection anyway. I know my Music Hall mmf 7 should sound better through the phono input. I'm just figuring, my IC-150 although in mint condition, is all factory old. Any idea's would be helpful. I do have a well trained ear.

Crown has always been more of a professional product. A 37 year old audiophile piece such as AR or Marantz will kill it. You really need to borrow a pre from someone or a local shop and see for yourself.

You do know that in the last 37 years, they have invented remote controls too...

Years ago I moved up from an IC-150 to an AR SP-4, another solid state unit. There was very noticeable improvement. Now have a First Sound Presence Deluxe and will never go back. Have fun in your quest for your favorite, but do not hesitate. It is easy to improve on the Crown.

Op amps have improved a lot since the 70's. The power supply caps will probably be dried out and need replacing too. Chances are that you will get a significant performance improvement with a modern equivalent SS preamp - what power amp and speakers are you using - is it a Crown 300?

Try, try before you buy. Find a dealer that has a business model that lets you try, try. That is the only way to tell what difference thee is.

The IC-150 is of course an IC (integrated circuit) based design. It was a decent component in its' day, but yes do move on.
If your cabling is also of that vintage you should also experiment with upgrading there. Your interconects & AC cord (which are now detachable, so you can try out different models of cords).
