Amp for Thiel cs5

[bigfishe]

Well I'm looking for a used amp or monoblocks to run a current hungry speaker
The Thiel cs5
Drops down to 2 ohms at 40 hz

Aleph 0 loved that load.

Lacking that, you build a simple push-pull follower Fet with lots of outputs and
heat sinks and power supply and bias the crap out of it.

What about the Os? And could I bridge it later on?
Maybe up grade to two.
Thank you Mr Pass

 

[Nelson Pass]

Os not so much. The charm of the 0 was that you could overlay the thd
vs power curves for 8, 4 or 2 ohms and get the same curve up to clipping.

It was developed around Thiel 3.6's.

That's awesome!!!!!

 

[bigfishe]

Well if you get any trade-ins let me know.
I'm ready to buy👍

 

[bigfishe]

Got the aleph 0 :-D
One issue tho one amp only works in balanced?
Any clue? Switch maybe?

U formed shortie plug , pushed in 1 & 3 holes in XLR

or decent quality XLR jack , with soldered bridge wire between pins 1 & 3

then RCA input will work

 

[bigfishe]

Thanks Zen!
I'll try that in the morning.
If it works does that mean I need a new switch???

 

[Zen Mod]

for my knowledge , Aleph 0 doesn't have that switch

I made a mistake in previous post , assuming that Aleph is having both RCA and XLR input connectors ; in fact , amp is having just XLRs , so all you need to feed it properly from unbalanced source is to make RCA-XLR interconnect , with XLR pins 1 and 3 joined/shorted

 

[bigfishe]

Mine are monoblocks and have a switch

 

[Zen Mod]

then check the switch : with switch closed , there must be short between XLR pins 1 & 3

open the amp , and check what's written on pcb - REV 1.?

 

[Nelson Pass]

Earlier units came with external RCA adaptors. Later on, switches.

Grounds #3 input just like ZM sez.

 

[bigfishe]

Geez it was the Speaker cable after all!
Amp Works perfect ;-D

 

[bigfishe]

I cant help but wonder if the amp could be made to run the new SITs?

 

[Zen Mod]

nope , without making completely different amp

 

[JeffCullen]

Aleph 1 (not 1.2) any better for Thiel 3.6? So hard to find.............. maybe only necessary if I intend to test the structural integrity of my home?

 

[bigfishe]

Pair of Aleph 0 on ebay right now for 3k!!!!

After living with these amps I have to say they are a perfect match to the
Thiel CS5i!!!
I've tried 5 amps on them so far ( not a looser in the bunch) and these
Are in a league of their own!!!!!
Out of all the amps played the Aleph 0 has absolute control over the woofers
This surprised me compared to the Eagle 2 one of the best bass amps I've ever heard. The Eagle has outstanding attack, The Aleph plays lower with liquidity and imaging bass notes wich I've only heard once at a close friends house.
The mids are what I expected clean and clear. Nothing sticks to the speakers. It just floats there . The highs are different then most solid state amps
No grain ,no etch ,but not rolled off either.
I really really like them :-D
