Mono and Stereo High-End Audio Magazine: Boulder 2160 Stereo Amplifier World Premiere

Thanks for posting the link Miziq. VERY impressive looking amp! Boulder's engineering and build quality are second to none, and this Class A powerhouse is no exception. If neutral and natural is your thing with incredible power, a 2160 stereo amp & 2110 preamp would be a killer combo & really the last amps you would ever need :thumbsup:.

Very impressive. They do not show the front panel in the photos. Does it look like the 2060 or is will they have have a mirror images pair like the 2050's?

Jim I believe the 2160's front panel is identical to the 2150 mono's which have had a lot of coverage in the Boulder forum :thumbsup:

Sure is a pretty piece of gear!!!:banana:

Cheers,

The very definition of a monster amplifier.

What's the price tag?

2160 - $54000
2150 - $98000
2110 - $54000

I've noticed Boulder haven't responded to emailed communications lately, so it's good you're posting some info Wizard so we're not completely in the dark....

I've never had trouble getting information from Rich Maez at Boulder so don't know what to say about this. I think Rich sometimes reads this forum so if you have questions maybe you should just post them.

Hi Guys,

I'm not sure what may have been going on with communications, but I haven't received any direct emails that have not been responded to (at least in the U.S.).

What is the 2160's input impedance?

200k ohms, balanced (100k ohms per leg); 100k ohms unbalanced.

What's the slew rate in V/uS of 2100 and 3000 amp series?

If I have an idea why you'd be asking about slew rate, I'd answer the question. Much like transformer kVA or damping factor, these are specifications that mean nothing on their own and were promoted as a way to play the specs game by a certain manufacturer in the '80s and '90s (they also liked to talk about maximum current delivery without telling anyone that a tweeter can be burned and smoked by even the smallest amplifier...) because that manufacturer knew that the average consumer had no idea what these specifications meant but they could be bandied about by both dealers who knew the consumer had no idea what they meant and the consumer who wanted to try to make some sort of qualitative judgement based on a numbers game. The highest slew rate in the world doesn't guarantee any specific type of performance parameter any more than the highest tire pressure means anything by itself when choosing a car. Simply looking at the distortion levels of any of our amplifiers at high frequencies and maximum power will indicate that they have enough voltage slew to handle just about any AUDIO-BASED signal you throw at them.

In short, the hundreds and hundreds of design decisions made in the overall topology and scheme of the amplifier as a whole make the product. So if you ask what the slew rate is because of ______, it'll lead me to understand exactly what it is you're trying to find out.

Rich
I appreciate your response. As a non-technical type I am more concerned about the end result than worry about what the numbers your engineers have been working towards.

That said it would be hard for anyone to look at your gear and believe corners have been cut anywhere in the parts quality or industrial design of your products.

High damping factor specs is so yesterday...

I'm a techie, and when I select components I see the specs as a whole.
I ask the manufacturer about the missing specs that I need, they tell me, but some don't - and say that the specs is good enough for you and won't tell.

This attitude will maybe work for most of the audiophiles, but for the most extreme audiophiles it will not work - we will loose interest in the product quickly.

I don't hear specs I heard the end result. Couldn't care less what the specs are.

Maybe that is the problem with the "most extreme audiophile" they are into the product and not the sound of the music.

For me the specs and the sound of the component is important.

Wizard: as a techie, you know that since slew rate is dependent on other factors, there is no such thing as a simple "slew rate specification." Fill in the rest of the information I need and I will provide you with the answer you want.

My main amp for the last 5 years has been a Boulder 2060 and the only amps I have heard that are better are also made by Boulder -- the 2160 and the scary 3060. Long before I bought the Boulder I wondered what could possibly make it worth what it cost. The published specs were impressive of course but other cheaper amps boasted similar or greater power ratings for example. The one spec I recall that stood out was the S/N ratio was higher than any other amp I was considering.

It was only when I heard it compared to other amps that I could conclude that, yeah, its worth the engineering and manufacturing effort they put in it and worth the price. I would not have even considered buying it before that. So, a single spec, out of context, may not provide useful information.

But Rich really should update the Boulder website to show the current product line. Didn't the last 2060 roll off the line last fall? But still no 2160 on the website.

If updating the web-site were my responsibility, the 2100 Series would have been up prior to CES! But because it's someone else's responsibility I'm at the mercy of their work schedule. No worries, though - I'm applying as much pressure as I can!
