The newest integrated amplifier from Pass Labs is the pure Class A INT-25. This conservatively rated 25 wpc beast of an amp is filled with all kinds of high-quality parts that were specifically selected and assembled by one of the greatest amplifier design teams on the planet.
2018 AXPONA, Aprl 13, 2018 — At Pass Labs we don’t change our products unless we feel that the changes are significant improvements over previous versions. Because of this our typical product life spans are eight to ten years.
Pass Labs doesn’t change up models unless they can make significant upgrades when compared to existing products, so when they introduced the new XP-17 Phono Preamplifier in 2017 as a replacement to their highly regarded XP-15, I knew that it would be a worthwhile trial.
At Pass Labs, we don't change our products unless we feel that the changes are significant improvements over previous versions. Because of this we see typical product life spans of seven to eight years.
Pass Labs has started shipping their new XA25 Class A Power Amplifier, the most affordable power amplifier in their current line...
The Pass Labs XA30.8 is a seemingly “low power” amplifier that one of the most uncompromised, cost no object amplifiers ever made at its power output level. It offers stupendous performance that the 30 WPC specification cannot hope to describe.
Pass Labs’ HPA-1 Headphone Amplifier is capable of delivering full-range dynamics across the entire frequency range, even when driving headphones that present difficult loads in terms...
With the success of the Pass Labs Xs series, Nelson Pass set out to create a line of additional power amplifiers that have most of what the Xs series has, but at much more affordable prices. The model under current review is the X600.8, which is a monoblock specified at 600 watts RMS output, with the first 50 watts in Pure Class A, and the rest in AB. Do they sound close to the Xs amplifiers? Read on.
Pass Labs recently introduced their new Xs Preamplifier and XS 300 Pure Class A (300 watts) monoblock power amplifiers. They are a completely new design compared to their previous components, and have a sound that is almost beyond description in words.
Recently, we reviewed the Pass Labs INT-150 integrated amplifier, which is biased into Class A at about 5 watts, and leaves Class A into Class AB at 10 watts peak. It is a superb integrated amplifier. The INT-150's brother, the INT-30A integrated amplifier, is Pure Class A throughout its 30 watt output (into 8 ohms) specification. Chris Eberle originally reviewed the INT-30A in 2012, and in this review, I compare the INT-30A with the INT-150, and add bench tests which were not in Chris' review.
Pass Labs is renown for their high end preamplifiers and power amplifiers, but they also have integrated amplifiers as well, which include the INT-30A and the INT-150. Here, we review the INT-150, which, as you can imagine from the model number, outputs 150 watts x 2 (into 8 ohms). It has the same massive build quality as the other Pass components I have reviewed, and also, its own distinctive sound, as I have found with the others.
In the past, we reviewed the Pass Labs XP-20 and XP-30 stereo preamplifiers. Now, we come full circle with a review of the remaining member of their preamplifier trio, the XP-10, which is the least expensive model. It is fully balanced, and has a slightly different sound character compared to the other two, which also sound different from one another. All three are great products, so you can choose based on price and/or sound characteristics.
