Tube preamps are great with Maggies and a high powered amp, that's exactly the set up I have.
I would suggest buying a good DAC (Benchmark, Bel Canto, Bryston, PS Audio) instead of a CD player to start, and use it to decode lossless files. An AppleTV or SONOS are great ways to start. You download your music once, then only have to search for it with the remote. If you spend your money on the DAC, I believe you will get much better sound, unless you move WAY up the CD foodchain. That's my experience at least. If you are not going to play vinyl, then the good DAC-Music Server is the best reasonably priced option.
Preamps, there are many excellent choices, I would start with used ARC, Conrad Johnson, McIntosh (I love the sound of the C2200), Cary, and Rogue.
One last thing, the Bryston 4Bsst is probably not going to really wake up your Maggies. I would cut your budget on the front end and start by looking at the 14 Bsst, that will make the Maggies sing. I had the 7BSST's (really the same thing as the 14bsst) previously and they were some of my all time favorite amps with Maggies. A very good match.
The 4b is not enough power to get the best out of the 3.6's. (I had one on my 3.5's-just not enough in any decent sized room. It just won't get the low end going IMO) I have not heard them with the classe cam 350's however.
Jonk78, I've been using a 4BSST for 3 years with my 3.6Rs and couldn't be happier. I'm running a CJ Premier 17LS tubed preamp, and think it is a great combo for my 14w X 23l x 13h room. Rich and lush. Bass response depends a lot on the room and how bright/reflective or carpeted/upholstered/absorptive it is. Everyone's listening room differs, so be cautious about advice from me and others.
I have 3.6s and recently upgraded my amp to Parasound JC-1 monoblocks which have been a great improvement over my Levinson 334. You can get them for under $4,000 used. There are numerous reviews on the JC-1s in the audio pubications and all are very positive. As for pre-amp, I am using an Audio Research LS-15 with some Amperex 7308 tubes from the early 60's which really make the LS-15 come alive. The LS-15 can be found for under $1500 and top flight NOS tubes (4) can be found for under $500, leaving you $3,000 for a CD player. Good luck in your search.
>>> 7BSST's (really the same thing as the 14bsst) >>
I jsut noticed this,,, 7BSST is almost same as 14BSST???
I can get 7B at half the price of 14B. (actually the 7B is the same price as 4B !)
So 7BSST will do fine?"
The 7BSST amp is a monoblock so you will need 2 of them so I highly doubt you will find a "pair" priced lower than a 14BSST amp or the same as a 4B amp. You are probably looking at the price of a single 7B amp (where you will need 2 of them)...
The 14BSST is pretty much 2 7B amps in one chassis although given it is a single chassis it does not have the total capacitance that 2 7BSST monoblocks will give you but that may not matter in your application. I have a 14B-SST amp mated to my 1.6 Maggies and it does a great job and can confidently advise it will do the same with a pair of 3.6's.
I tried a 4bsst with my 3.6r's and the sound in my room was a bit bright and lacking in bass.Not enough power. Along came my Classe CA-400 that puts out 800w at 4 ohms and all is well.Used prices for these are in the low 2K range.
The Classe CAM350 as you listed would be an excellent match for a smooth sound.
Agree with Bob reynolds and Ackman00. You should audition the Parasound JC 1's. They great sounding amp's. Check out Stereophile January 2010 issue. M. Fremer compare them to Bryston 7Bsst'2, he likes the Parasound JC 1 better. According to John Atkinson's measurement test. The Bryston's has low input impedance that may be problem matching with preamp specialy tube pre and in his measurement into 2-ohms load the Bryston 7Bsst'2 didn't do as well as the other amp's tested.
I had the Parasounds in my system a few years back, I really loved those too. Excellent choice. I don't know that I liked them better than the Bryston's, because they were a couple iterations of amps apart, but I did really like both of them.
