Review 1 of 45

Price Paid:  $0.00 from used

Summary:
I bought this amp used for a very good price used and have used it for about three months. I am a little short on time so all comments will be in the strengths and weaknesses. Please note that the review is for the Aleph 30.

Strengths:
This is the best amp I have ever heard from 200hz up period. Everything is perfectly balanced from the upper bass through the treble. The low end from 40-200hz is good but a little light.

Weaknesses:
The aforementioned light bass is a weakness but I am not sure it is possible for one amp to have huge punch in the low end and remain totally accurate throughout the whole audio spectrum. The damping factor is either 100 or 200 (I don't have the manual in front of me). The Parasound amps I have used have damping factors of 800 and much more bass punch, but they sound a little bright and unbalanced comparatively. However, bass is not an issue because I am using a sub.

Similar Products Used:
All my speakers are homemade.
Pair one is an 8" two way with a Morel tweeter and Vifa woofer. These are sealed with a sealed sub and I have listened to this system the most.

Pair two is a MTM with a Scan Speak tweeter and 2 Scan Speak woofers. These are vented and have plenty of bass w/o a sub. With the parasound amps these were a bit bright which was ameliorated wiith the Aleph 30. Notwithstanding, I need to redo the crossover.

System:
Preamp: Parasound pld 1100
Cd: Nakamichi MB 10
DAC: Rotel
Speaker cables and Interconnects: All Alpha Core

Other amps used include the Parasound HCA-1000A and HCA-1200II

Review 2 of 45

Price Paid:  $1400.00 from na

Summary:
I have a previous review on this amp 2 or 3 years ago. I have not changed my mind and I have new and renewed love for this amp. As my system have grown up from hi fi to hi end I found this is a great amp, as great as one of the biggest shining stars of the hi end can be. Now my system have an upgraded Esoteric DV-50 player, Rotel CD as tranport and Wavelenght Cosine DAC, Audible Illusions M3 and Pass Labs X2.5 preamps, VAC Aurice Stereo amp, AQ Dragon speaker cables, Alpha Core TQ2 and Kimber KAGC interconnects. Clearaudio Solution table with two Rega RB-600 arms, Krell KPE phono pre, Re Rose Rosette phono pre, Clearaudio Victory H and Benz L2 cartridges. Audio Physic Virgo III luodspeakers. The Aleph 3 is from the lower midband to the highs pure music, transparent, very correct in all ways. I few words is a very very good amp, better than I was thinking some time ago. This amp sound as good as the other electronic associated to the system. If you use a low cost or low quality electronic, the amp may be sound terrible. But if you use good electronics the Aleph 3 sound will be only limited for the quality of these electronics. In another system I hear the aleph 3 with a Wadia 861, and custom built loudspeakers (truly amazing this loudspeakers), I heard the same performance that I mentioned above. May be the bass is not deep, but is very controlled and tight. If you want power and deep bass use the PS Audio HCA-2. I own one of this amps for two years now and this is a little amp with thunderous bass and big power.

Strengths:
From low midband to highs is the best amp for the money and beyond.

Weaknesses:
Bass, but not to much.

Review 3 of 45

Price Paid:  $1500.00 from used from a friend

Summary:
I believe that the Aleph Range of Pass Labs amplifiers will be the stuff talked about over the campfires. :) Legends !!! I had just taken over an Aleph 3 from a friend and have been smiling from ear to ear eversince. I gave up a pair of 60watters for one pc of the Aleph 3. Wow !!! But no regrets, in fact all smiles. My former Brystons were not second to the Aleph 3 but there was that magical feel that each instrument floats in it's space in air, is something that I have not heard in any other system that I have come acrossed. And these systems cost many times the Aleph 3. One example is a Gryphon system. It's a solid state amp that has the warmth of a valve amplifier but the speed and dynamics of a solid state. Produces well controlled bass, sweet highs, a rich midrange, and imaging that's unbelieveable. I am sure not everyone will agree with me, but I am enjoying my system so much that I had to share this joy here. You have to listen to a Pass Lab to believe it. Kuddos to Mr. Nelson Pass. :)

Strengths:
It does everything well, when you get it to play alongside the right equipment.

Weaknesses:
You kidding.

Review 4 of 45

Price Paid:  $550.00 from Digikey, Mouser

Summary:
Before I start this review I want to personally thank Nelson Pass and Wayne Coulburn of Pass labs, without these fine people this would have never have happened, also thanks to my father in law Bjarne (Paul) Lysholdt, electrical genious who helped as well. I was on a quest to have a great amplifier, not just an out of the ordinary one, but one that would be able to put a smile on my face and a tear in my eye at the same time. I wanted a SET, but more power. I researched the internet over and over and it seemed my best choice that it would be an Aleph. I did not have the money to actually buy one, new or used, so I decided to enbark on a journey on building my own, and mind you it was not a short one. I didn't know + and - 25 volts (rails) I thougt it was just 25 volts not 50! Matching mosfets, what is that? But I learned a lot in a short period of time and could have never did it by myself, again thanks to all parties involved. I won't go into specifics of how I did it or what I used, just that I did get it done, the single most gratest achievement in my life. Performance, well I don't know quite how to explain it, But what I hear really moves me, everything is accurate, beyond anything I could have imagined perhaps. Magic might be a one word description, beyond the fact that it worked from day 1 and never faultered either. Accuracy, 3D sound like I have never hear before, with a lot of life, Bass is very good and acurate, just cannot get enough of it! It has transformed my thinking on audio more than anything has or could ever. It is now a classic and will stay with me as long as I live, will not be for sale now or ever! To conclude, nothing in my life except for getting married to my lovely wife, can compare to this experience and the willing support of a major player in the audio world, my hat is off to Pass labs for very personal service and advice they provided!

Strengths:
Real audio, what an amplifier is meant to do, boost sound and not color it. Could be a work of art (so iv'e been told) but am not an expert. Will make you smile and cry at the same time. Accurate, lively, and VERY spacious sound!

Weaknesses:
My back and some other parts of my body.

Review 5 of 45

Price Paid:  $800.00 from used

Summary:
I must say I was somewhat skeptical about selling my Audio Research D52b amplifier to buy the Pass Labs. I really enjoyed the sound of my Audio Research and it was by far the best amp I had ever owned. But after reading the rave reviews on the net, I decided to take the plunge! I was plesantly surprised to find that the Aleph 3 met or exceeded all of my expectations. The detail that this amp delivers is amazing. I am hearing things in my CD's I never knew were there, and the soundstage is incredible. I honestly noticed the improvement over my Audio Research amp, and that is saying alot! The Aleph 3 will make poor recordings sound very poor, because it represents the music the way it was recorded, good or bad. But on good recordings the sound is nothing short of miraculous. And this amp has very good bass. I really don't see what all the fuss is about the lack of bass. Quite simply, this is the finest sounding amp I have ever heard! I am using the amp with a pair of Klipsch La Scala's, so the 30 wpc is more than enough. And my pre-amp's are an Audio Research SP5 and Audio Research SP6b, with a Technics DVD A10 DVD\CD player.Monster speaker wire and interconnects.

Strengths:
Stunning sound, wonderful detail, very good bass. Excellant construction.

Weaknesses:
Will make bad recordings sound real bad!
