Need a Preamp Recommendation


Newbie here, please bear with me. 2 channel system:

PSB Image T45 speakers and a Onkyo M-282 200 watt amp. I am currently using an old pioneer receiver for the preamp. Looking to upgrade on a budget. Would this change the sound drastically? If so, what are some recommendations?

Thanks in advance.

Thanks for the feedback. I need to spend no more than $400. I pretty much listen to all types of music. Also, I would need a remote. I've got access to a Marantz AV-600 from a friend. I think I am going to test it out soon at home and see how it sounds. I think I could get it from him for around $150.
Do try the Audiolab 8000C preamp. This should be what you are looking for and the price is within your budget.
Well, the Marantz AV-600 sounded ok and better than my Pioneer, but it is too video heavy for my needs.
