PRE and AMPS same brand ? or different brand?

Jin just get started with whatever you can reasonably afford, & experiment with synergy later on as the budget allows. I've seen this work both ways so you never know, but if you wait & wait until it's completely affordable then the stuff may even be obsoleted by then? Regarding bridging, I suggest against doing that simply because damping factor degrades by half when you bridge an amp, so degraded control of the speaker by the amp is inevietable.
One approach that many of us take in order to balance out a system is to tune it with cabling & tweaks. This includes interconnects, speaker cables, upgrade AC cords, vibration control & isolation products, tube rolling (if tubes are in the picture), AC power conditioning, even your listening room itself.

First of all I would say if you had to decide over a nice amp or preamp to start I would go with the nice preamp. Especially if it is for home theater. The preamp is the heart of your system and it actualy amplifies the signal (percentage wise) more then your amplifier.

Amplifiers are also much more adaptable to upgrades. You can start with one and then later add a second one and bridge them or bi amp them. You can also move them around. Get a better amp down the road and put the old one on the rear channel.

Dont get overwelmed by synergy and enjoy the learning and tweeking of components. Audio Nirvana is an endless journey and its the journey itself that is the fun.

thank you for the help again ..

i have somewhat a problem starting with a preamp and that is, i want to get something that will be HT compatible..and there isn't a lot of choice in nice sounding preamps/processors..and they are not affordable for me at the moment, and won't be until some time ..

maybe i should just get a nice stereo setup that will sound good cause neway my gears will be sued 80-90% of the time in stereo .. and forget about the HT for now ( i don't have a lot of place in my room neway. .)
i think i'll get HT for my parents in the living room,and just get a dam nice stereo setup for me in my room :)

i was going to buy ( with there money..not mine ahah )
them a Nakamichi Soundspace 11, but after browsing through here, i think that with the same money involved, one ca get a better system with sound that will be more alive..

what are your thoughts on a complete nakamichi soundpsace system for HT use ? it's supposed to be all balanced rightly to work together .. but i fear about the performance/$$$ factor ..

thanks..
