Cello audio Palate or Suite still worth buying?

I read so much about these preamps that I am wondering at this late date are they still worth considering? I have read that the modules go bad and they are very hard to source. How would they rate from a sonic perspective with today's best. What got me thinking is that I bought a classic speaker system and have been bowled over with how great it is. Would I experience the same thing with the Cello products? Bob
