CD ripper


I have a sizable CD collection that I would like to make DSD files from. 
Looking for a decent ripper. 
I have a pair of really old Bevridge System 3 speakers that badly need restoring so my current listening setup is:

Fostex HP A8C and Fostex TH900 headphones. About to order LS50s.  Not sure if I want to go passive or powered.

Is it necessary to spend much on a high end ripper?  Trying to figure out a budget.

Thanks!

Hey Guys, a question please:  I read many of the comments on this thread and did a search for : EAC CD ripper.  What I found were a no. of sites that offered downloads, but also, I found many COMPLAINTS about forced adds and some people even said that their browsers were modified. Will those of you who have used the EAC product weigh in on these issues.Thanks in advance

 EAC has no forced ads or malware. Search for Exact Audio Copy.  EAC an the abbreviation. Download it from the developers site, not the free download sites that are usually full of popups. 

 I have never heard of any complaints about malware in EAC. I have been using it for over 10 years with absolutely no problems.
