Pass Aleph 30 and 60

Elduende14,

By the way Nelson Pass has set up another company called First Watt. He is marketing a number of lower power class A amplifiers designed for high sensitivity speakers. One of the amps the "Aleph X" is supposed to sound remarkable with high sensitivity speakers. Because your Tannoys are 94dB this is a real option. The scuttlebutt is that these amps will be very reasonably priced. Nelson has stated the amps should be ready soon. The web site is http://www.forstwatt.com. Stay tuned......

Sorry, That is http://www.firstwatt.com

Liguy-I didnt 'make up' this.
I remember reading about all that I wrote before the first Volksamp hit the shores.
There is a difference in design also besides the balanced input.
The 30 has a tad more power than the real aleph-3

David,

Wrong again. The Aleph 3 has a little more power at 4 ohms. There has been some component changes in the Aleph30 but the design is the same. Have a look at the schematics. There are no differences in topology. This is from the Aleph 30 manual:

Gain 20 dB balanced, 26 dB single ended
Freq. Response - 0.5 dB @ 2 Hz, -1.5 dB @ 100 KHz
Power Output 30 watts/ch @ 8 ohms, 40 watts @ 4 ohms
Maximum Output 25 volts, 5 amps
Distortion (1KHz) 0.2% @ 30 watts, 8 ohms
Input Impedance 47 Kohm single-ended, 52 Kohm differential
Damping factor 100
Crosstalk > -80 dB 20-20 KHz
Balanced Input Rejection -50 dB typical CMRR
Output Noise < 500 uV unweighted
Random noise floor 5 uV typical
DC offset < 100 mv
Power Consumption 200 watts
Temperature 25 degrees C. above ambient
Dimensions 17 " W x 15.5" D x 5.5" H
Shipping Weight 45 lb.

This is from the Aleph 3:

60 watts/ch 4 ohms
60 watts/ch 2 ohms
Maximum Output 23 volts, 8 amps
Distortion (1KHz) 0.2% @ 30 watts, 8 ohms
1% @ 60 watts, 4 ohms
1% @ 60 watts, 2 ohms
Input Impedance 23 Kohm
Damping factor 100

I have built enough Alephs, so I know this cold.

LIGUY

You are very knowledgeable on this stuff, so perhaps you can answer my question:

Just about every SINGLE-ENDED amp on the planet - including most of the FIRST WATT models - drop power into lower impedances.

This was very true of my 30w FIRST WATT J2, which was down to 12w into 4 Ohms.  This is the reason I eventually sold the gorgeous J2.

So how is it that the little ALEPH 30 can produce 30w into 8 Ohms and 40w into 4 Ohms?

What gives?
