I understand that you need to have some idea about what you might be spending on electronics in order to know how much you have to spend on speakers. Nevertheless,I strongly recommend that you settle on speakers first, because the differences there are vast, compared to the differences further upstream. As evidence of this, consider that some speakers can mask the differences between amps and CD players, whereas no decent electronics can ever mask the differences between speakers. One of the advantages of this approach is that you might find that you do not need new electronics and, if you do, you can select the electronics that fit well with the speakers. Speaking of electronics, I do not think that it is worth your money to move from a 50 [or 65?] watt amp to a 75 watt amp. As long as you are paying for a change, you should at least step up to 100 watts which could be helpful in your new larger room, unless you choose efficient speakers [which takes us back to the point of choosing speakers first]. I would not buy a component that combines long living parts [amp, pre-amp, tuner] with parts that have a shorter life [mechanical parts of tape and CD and DVD players]. I am a dealer, so I will not make comments on this forum on the brands you are considering or not considering.
