    Default McIntosh Teaches Its 50-Year-Old Tube Amp a Few New Tricks






    No, McIntosh hasn't gone and designed an everlasting vacuum tube. But it has built an indicator into each tube which will alert you to which specific tubes have gone bad. This saves you time and money tracking down a niche repair shop. Also, if you haven't noticed, this thing is also slick looking.

    This is the 50th anniversary edition of the MC275, a product built to endure decades of use. Able to push 75 wats into 4,8 or 16 ohms, the latest edition of the MC275 has a frequency response of 10Hz-70,000Hz with a tolerance of +/- 0.5db between the 20Hz-20,000Hz range. And if you're looking to go all out with your sound system, the amp can be yours in December for $6500.

    I will take a pair of Krell Mono Blocks any day of the week over any tube amp. Let's move on people and get out of the 1950's

    And modern tubes are used by militaries, hospitals, broadcast stations, guitar amps, and a variety of high-voltage equipment all over the world.

    A good tube amp is a good amp. A good sold-state amp is a good amp. Tube or transistor, good is good.

    I will agree partly. Not sure where tubes are used in the military or hospital though. I work in a hospital with high voltage and the only tube I use is an X-ray tube and I am pretty certain it does not sound very good There have been so many articles written about the sonic disadvantages of tubes that I don't care even go into it any more. If tubes amps were sonically superior to solid state amps then companies like Krell, Levinson, Parasound, etc, etc, would use them. They aren't and they don't and tube amps are a just a niche. That's the truth. If a person likes them that's fine by me. I have heard some in the recent past and they colored the sound something awful. It reminded me taking an EQ and sliding all the midrange frequencies down. It may have just been that particular amp but I was not impressed. There is really no reason to use tubes in an amp any more other than for nostalgia. Even if they sounded as good as the best solid state amps why use them? There is nothing wrong with nostalgia don't get me wrong, but I don't much care for it in audio/video equipment. I just got rid of the last tube tv the other day and good riddance to that thing.

    I certainly think and understand that tube amps have their place and use in guitar amps and the like, and there is a reason they are used for those purposes. For high end audio reproduction I don't think tube amps really have a place anymore. Anyway that just my opinion. OK rant over I have had several drinks and now I just want to listen to my solid state amp with some people playing some guitars through tube amps.

    Likewise, there have been so many articles written about the sonic disadvantages of solid state that I lost count a long, long time ago. If solid state amps were sonically superior to tube amps, then companies like Audio Research, Conrad-Johnson, Lamm, Manley, Wavac, etc., etc., would use them.

    Ultimately, sonic superiority is subjective, because what a thing sounds like, just like what a thing looks like, is constructed by the brain; and the brain is something we are only just beginning to understand. Since sound is subjective, there will always be people who can't abide the sound of tube amps, and people who can't abide the sound of solid-state amps. Neither is sonically superior to the other in any ultimate sense.

    Solid-state amps definitely have non-sonic advantages over tubes (though companies like Krell, etc., tend to neutralize some of them by building solid-state amps every bit as big, heavy, and hot as a tube amp). You rarely have to replace capacitors or opamps, for example. OTOH, because tubes have to be replaced and therefore are replaceable, a tube amp can be customized to a great degree by the owner.

    If you really want to get modern about your amp technology, you have to go with those ICE modules that B&O came out with a few years ago. Other than B&O, though, I think Bel Canto may be the only company using them heavily. Pioneer used them for a while in some products, but seems to have stopped. I know there are a couple others that have used them, but I can't remember who they were.

    Those mono block Krells are beasts aren't they? They certainly must put off some BTU's I would think. I would take 5 of them though if someone were giving them to me

    I think Rotel is making some digital amps or something. A few others too. Not sure how well they perform though.

    Update: Rotel has some class D amps now so nothing really new about that. The truth is amp technology has really not changed all that much since the 60's. Until we get a laser amp or Particle amp or some wild technology nothing is really much different. That is one reason my little old Adcom GFA 535II still sounds as good as many things made today.

    Great thing about McIntosh is they make both.. Here is a little 600 watt...mono.

    Btw, I have both Krell and McIntosh.

    Looks like a beast, funny how some people say the Emotiva's are ugly when they look much better than the Mcintosh do on the outside. Myself I could care less how an amp looks and mine are all in a closet anyway so who cares. I am after performance/price.
