However, u can suggest me hardware names that i can seriously work on as i am so intensional to bring forward my ideas to light can be big a concern.
Well, of course I believe you should give Teensy 3.2 a try! My opinion is biased, since I'm the guy who designed Teensy and the Teensy Audio Library.
My new features that i want to include: Detuned Hypersaw oscillators, Granular lookup tables, Formant Filters and Phase Modulation.
As you can see in the tutorial video, and also in the design tool (on the left, scroll down to the synth, filter, and effects sections), the library already has most of the building blocks (oscillators, filters, delay effects) for the stuff you want to do.
You'll probably need to add your own objects to the library for specific synthesis, like specialized granules. But the software infrastructure is all there, and many similar objects already exist, so you only have to write the code which fills small arrays with the samples you synthesize and just transmit the buffer to the rest of the library. The hard parts like efficiently dealing with data transfer to hardware, and just all the work of creating all the other library pieces like mixers, sample player, etc is already done.

Go with that board.
That Synth Core A does look pretty amazing. But does it have working software? Does the software support efficient DMA-based data movement? (which allows the CPU to remain mostly free to actually synthesize samples)
I can tell you from the last 2 years of experience that the software part is FAR more work than creating the hardware. If you want to spend all your time working on that difficult low-level driver stuff, by all means jump onto a project that's only at the initial hardware stage. But if you want to spend your effort doing synthesis, look for a platform which has working hardware and software infrastructure, or at least good quality drivers to move your samples to the DAC chip.
You might also look into whether Synth Core A is still active. The last update on its news page was in 2011.
