an old boring question but... please help me

[xsnailx]

hello!

ok! after a couple of hours of thinking and reading i
want to ask what kind amplifier
will suit my speakers best?
here is my cosiderations
2 zens v 4 running in a bi amp mode
one aleph x or one aleph 3
or even 2 aleph x or 2 aleph 3 in a bi amp mode
maybe another aleph instead?

both of them will work with bride of zen preamp
or balanced line stage pre

my speakers specs:
sensitivity 1W @ 1m - 88 dB
impedance - 6 Ohm
frequency area +/- 3dB - 30 - 23 000 Hz
Crossover frequency - 3 kHz
system 2 way.- Basreflex
authentic voice model 221

i have seen some people from poland here
so i will be pleased to know about good source of
radiators and aluminium plates in poland?
maybe some of you
(from poland) have any pcb's for sale?

[xsnailx]

definitly it will be an aleph 3 or aleph x
if the power will be not enough. i will run them in bi-amp mode
but the second problem remains:<
so i beg anyone from poland to help me
please

ps. is aleph x much harder to bylid than aleph 3? from that what i have read they are ot as easy as zen but ... on the same level?

I haven't built any of them yet, though I plan to build the Aleph-X with Chad's boards. From what I have read, the AX requires quite a bit of tweaking, whereas the Aleph 3 is more "plug and play".

ok i will be definitly building aleph 3
but i cannot stop thinking about zen:>

i will proably try to make my own pcb layout or even use silver p2p wiring instead

Assuming that the design is correct, the Aleph X requires
no tweaking, apart from a pot on the current source
feeding the diff pair to adjust the absolute offset DC.

[xsnailx]

so lets sum things up:>

1) i have read as much as i can about aleph x but as it is my first experience with aleph amplifiers i will certainly go for a classical aleph

2)at this moment i need to determine wich one

3)i will use one layer pcb

5) i need to find out where to buy sinks and aluminium plates

nd the zen v4 is still on my mind :>
but i dont know if 1 bi amped zen per channel will be enough in my case ???

[xsnailx]

may be not definitly but at 95%
the others i consider are aleph 5 or aleph 30 (aka volksamp 30?) and double zens

I stand (or sit) corrected, then. I was just going by the discussion in the Aleph-X thread, where there are many warnings to the tune of "this project is not suitable for beginners", etc.

[xsnailx]

i have read them too! and decided to go for classic aleph not an x

[xsnailx]

aleph 5

but i beg anyone from poland and maybe czech republic please help me
i have some issuse getting proper heatsinks and irfp244
so i will be pleased with every information bout them

ps i will use pcbs from there
