The 88 has been discontinued and replaced by the more expensive but internally similar 99 - there is no evidence that the 99 is any better sounding. AV123.com sells the 99 they may have some old 88s left - the 88 was $300 the 99 is I think $100 more. If you go to www.headfi.org there are some threads in the dedicated sources forum detailing the opamp replacement procedure...

I owned an 88 I liked it but found it a bit thin sounding for my tastes YMMV and so on, certainly at $300 it was a good bargain being fundamentally a Musichall CD25 - blah drone etc.
