I jumped into this hobby with no experience, as green as newbie can be, and purchased mono bloc SS amps and a tube preamp. My Denon 3806AVR and DVD/CDP produced horrible 2 channel sound from my Monitor Audio 9i Speakers. I performed just enough research to determine that the Denon 3806 was not a good match for driving the Monitor Audio's for 2 channel sound thus the decision for the amps and preamp. Honestly, I believe I could have been happy if I had not lurked around AC and later joined AN to get totally absorbed in the Nervosa of Audio.
Everyone's situation for compiling a 2 channel system is probably unique and many, like me, don't start out having a real vision about their system. Based on the journey I have taken, so far, I would definitely recommend:
1. Select the speakers and try to fall in love with highly efficient speakers to provide you with both more options and more economical power options especially if you want to use tube amps.
2. Select good amps to drive the speakers.
3 Select the source (Streaming, Turntable, or CDP). I believe this is the second most critical decision to the outcome of the sound from the system. There are just so many choices and decisions that are spin-offs of the basic choice of type of source, ie., will you need a DAC, do you need mods to the source, do you need an improved power supply, should I use a digital or analog connection, etc. etc. etc.
4. Select the appropriate Preamp
5. Do a lot of homework and purchase ICs carefully.
6. Avoid aftermarket PCs until you begin tweeking the system.
7. I have not attacked room accoustics yet but I know it is a must for my room and probably for most rooms to maximize the potential of a system. However, I am reaching a point where I am approaching the 95% + capability of the gear potential of the system. To get the last 5%, gear wise, I will have to purchase $1,000.00/meter ICs and SCs and have expensive upgrades to the wiring & crossovers of the speakers. Personally, I will never (and you are not suppose to say never) and I mean never go there with this system. This means I have to convince Vera to tolerate me rearranging and treating the room. Guys, lets face reality, we like our systems but I, for one, don't like sleeping with it so the WAF is also extremely important to the final outcome.
