Forgive me if I exclude any others in the top-tier integrated category, but the Gryphon Diablo 300, Dartzeel CTH-8550 mk2, Constellation Argo, Ypsilon Phaethon, Vitus MP-I201 (significantly more expensive than the Humboldt) and SIA-030, Pilium Leonidas, Absolare Integrated SE, Soulution 530, CH Precision I1 are all world class. The mighty Vitus MP-I201 sits regally at around $120k and, sadly, I have never heard it, so I cannot comment on its performance or value. Price-wise, the Humboldt sits at the penultimate price position, with the others ranging from the mid-$20k’s to the high $40k’s. Sonically, the Humboldt offers pure neutrality, an insanely low noise floor, and supreme dynamic prowess, while conveying music with passion, soul, and energy. The other choices I listed are all damn good, and range in personality from warm and engulfing, to ultra-dynamic, to hyper-accurate and resolving. I’d put the $40k Leonidas and the $40k Vitus SIA-030 as the most comparable tonally. Your listening tastes, budget, and current equipment will help to define which direction you need to look in. As a reviewer, it’s not my job to tell you what’s better or worse, or what to buy. It is my job to tell you what the review subject sounds like, and what’s worth an audition, and if it’s something I would consider purchasing. Well, the Humboldt is unquestionably worth listening to and absolutely worth buying if you have the means. I was sad to see it go, and even sadder the following day when it was no longer in my room. Highly recommended.

While the phono stage’s 47ohm moving magnet input impedance will work well with pretty much any cartridge of that type, it’s a little odd that Yamaha has chosen to go with a 50ohm value for the moving coil option. While MCs vary in terms of their loading requirements, a 100ohm value would have suited many more cartridges. It’s not a make-or-break situation, but you’ll need to be careful with the cartridge choice if you want optimal results.

How did the Parasounds perform on more delicate fare? You’ll get few quibbles from me, friends. There were moments when I was simply startled by the finesse that they offered. On Louis Bellson’s album Thunderbird, for example, I was smitten by the rendition of the Neal Hefti standard “Softly With Feeling.” The Parasounds were able to provide the hushed backing of the winds with total control, endowing the song with a sense of realism that it would otherwise have lacked. This was one of those times when this LP on the Impulse! label really sounded opened up rather than claustrophobic. I mean talk about pristine. Suffice it to say, that the Parasounds conveyed, or appeared to convey, just about every last little nuance the cartridge excavated from the black grooves.

But even on the delicate passages, the sound was never wispy. Take the magnificent album Festival of Trumpets [Nonesuch]. It was mastered in 1974 by Bob Ludwig and features the New York Trumpet Ensemble, directed by Gerard Schwarz. I was riveted, among other things, by a lovely Sonatina by the baroque composer Johann Christoph Pezel, who himself  played trumpet and violin. The gossamer-like trumpet playing of Schwarz and Louis Ranger sounded very enticing, but it was the accompaniment of the bassoon and harpsichord that really caught my ear. It’s easy for them to get lost in the mix. But here it was easy to hear the pleasingly sonorous sound of the bassoon as it puffed along, as well as the soft and deliberate plucks of the harpsichord. If I had to pick a nit, it would be in the treble. It’s not that the sound ever became hard or dirty—the Parasound always has a rich, warm, inviting sound on top—rather, the amp could sometimes be less slightly transparent and pellucid on top than some of its far-pricier brethren.

This streaming DAC/power amp combination has a lot going for it – gorgeous looks and a sound and build quality to match. It’s simple both to install and use, and you won’t need any tweakery to tease out their best. Cambridge Audio has got its ‘no limits’ series pretty much bang-on, and anyone who still thinks the brand is just about ‘budget hi-fi’ needs to know it’s playing with the big boys now – with great success.

At the beginning of this review, we called the M33 an innovative new design. Looking at the distortion and noise results above we can confirm this. We believe this is the best performance to date of a stereo or AV product, that has no analog volume stage. It’s the AKM AK5578 chip used with four converters processing one channel. Wired this way this ADCs performance is about as good as can be achieved from a single chip. We know of no other consumer product with this ADC performance. We believe we are the first to extensively examine the preamp-out performance of the M33 and note the performance standard it has set. Only a relay-based analog volume or a volume using an exotic current mode multiplying DAC with laser trimmed film resistors will provide a significant improvement over what we see here.

“Are triode tubes the answer for everything? Like everything else, triodes have their limitations. In the case of these ancient triode tubes that were born in the 20-30s, they have very low-efficiency. So when we design around with these triode tubes, we need to make sure to use preamp tubes that have a good enough voltage range to drive them. Although, these triodes are on the lower side of efficiency compared to newer and other types of power tubes, there are still many choices of tubes to use as the driver, and the 6SN7 / CV181 is one of them. We like the 6SN7 / CV181 very much with its good-ole tube sound and flavor, over the more controlled and quieter 9-pin preamp tubes. The 9-pin preamp tubes are sometimes too “perfect” or synthetic sounding for tube connoisseurs. Like the triode tubes, the 6SN7 is also a very rugged and durable tube. Getting a quiet 6SN7 is difficult today. Recently we bought 10 new premium versions of 6SN7s, and 6 of them we tested were microphonic, and we had to send back.”

These aren’t the kinds of differences that will make B135 SST² owners run out and sell their amps—the gap in performance was no gulf. However, if I had the choice of buying one or the other and sound was the only factor, I’d opt for the B135³. As I switched back and forth between them, it was sometimes hard to pinpoint exactly what difference I was hearing—yet I consistently heard an overall smoothness to the sound of the B135³ that was incredibly easy on my ears. When I reviewed my listening notes, I found the nouns ease and easiness sprinkled throughout. Evidently, that was the consistent impression I was left with.
