Evo ja neću biti isključiv ali čika Nelson kaže ovo:Meanwhile, it’s been about 13 years since I designed the Aleph 3, and I have such affection for that series that I revisited the design. I wanted to better address the customer who owns high efficiency loudspeakers and maybe a tube preamp. From my experience with small amplifiers I know that this person values the naturalness and musicality of the amplifier’s sound over specifications. The logical alternative is a high quality tube amp. Am I trying to emulate a tube amplifier? No, but I make use of some of the principles that make tubes sound good - simplicity and linearity. Toward that end, I wanted to simplify the signal path and reduce negative feedback without giving up on the measured performance.
The Aleph J carries on in the tradition of the Pass Labs Aleph series, combining those elements that were particularly right about the Aleph 3 and 30, and re-thinking those areas open to improvement. Unlike its First Watt predecessors the F1 and F2, the Aleph J is a voltage source amplifier – a regular sort of amplifier like the ones you already know and love. There are differences between the Aleph J and its predecessors: 1) Improved power supply filtration with about 20 dB less voltage ripple 2) Reduced gain on the active current source, giving better overall performance into 8-16 ohm loads
2) Reduced gain on the active current source, giving better overall performance into 8-16 ohm loads 3) Input stage using high quality matched JFETs 4) Much higher input impedance and vanishing capacitance 5) 15 dB less negative feedback. 6) Even greater stability, operating without lag compensation 7) 15 dB less noise 8) No electrolytic capacitor in the signal path
Inače,slažem se sa tobom da mu treba kvalitetan preamp da bi prosvirao kako treba (probao mog Babela do sada sa bar 10-ak preampa a za zvučnike ostajem pri svom stavu-bar 8oma i što osetljiviji...
