As an architect, I try to apply the same logic and thinking that was presented in this video. Proven methods and technologies are enduring and contribute to the overall quality of the experience.
Although my 1998 integrated Simaudio amp is not the most transparent in my collection ,it is the most organically musical and most enjoyable i own ! a keeper 'till i croak ....
Most of the new things are design to be thrown away, non-repairable. Just about any technician will say they can fix a 50 year old amp but they cannot fix a 3 year old digital amp with all the logic controls. It is very sad when the world is talking about reduce, reuse and recycle.
In your opinion, which is a better amp for the $300 power supply conversion: the Yamaha AS301 or the Cambridge Audio AXA25? It looks like the Yamaha probably has more room internally for the capacitors?
Based on the picture on the net of the AXA25, it has way more room than the Yamaha. However, AXA25 is no longer available in Canada. They still sell in Europe as far as we know but not in Canada nor USA. AXA25 is a better amp for modification than the Yamaha AS301. It doesn't have any logic controls.
Can I buy a Yamaha AS-801 with modifications done and delivered ? I am far from you but I am really interested. you are 790KM away. I live near Montréal
Perhaps to you it is. However we have years of prove mechanical switches can be repaired and logic circuits are a throw away. All the surround receivers which last only 5 to 10 years. Manufactures don't wantnto support them because they need to keep selling more new boxes. Not us. We want things to last a long time and we are building thing to do just that.
I have the Cambridge axr85 and the Yamaha a-s501 which I purchased both at about the same time. The Cambridge axr85is running fine, I just got word from Yamaha repair calling to confirm my shipping address to send back the a-s501 they've had for about 4-5 months. I haven't had the both of them long enough to compare and select my favorite of the 2, I'm looking forward to it.
I don't understand the reasoning behind the statement that an analog pot for the volume control for example can be replaced, but the digital circuit cannot be repaired. That's nonsense. Digital inputs knobs are attached to rotary encoders which is a pair of on and off switches that create two square waves as you rotate it. They can be replaced easily if something goes wrong with them. if you're saying that the digital logic controller might go bad, that's a very rare thing.
@@fredflintstone8048The encoder is usually not the peoblem. The eprom is. In the case of surround sound receiver, the HDMI chip is usually the problem. If the manufacure don't want to support the model anymore, usually there isn't any other way to repair it. The amount of unrepairable surround sound receivers we have piled up here is a good indication how many of them are total garbage after 5 to 10 years. Manufacturers tend to like selling new units because it is how they make money. Repairing models with old technogy are usually not what they want. Unless it is higher end 2 channels unit. Multi channels are usually a throw away things.
This is faulty logic. Logic circuits dont slowly degrade over time where as a mechanical knob may due to contact with the carbon ..etc. Sure eventually a logic circuit may fail I've got electronics that are well into 40 years that have some sort of logic and still working.
Agree on the logic circuits don't slowly degrade. They will either work or doesn't. Like yourself, I have many logic circuits like CD players that still work after 30 to 40 years of service. However, the main problem of the logic circuits are the newer surround sound receivers which has a lot more complex logic and way more features than most people would ever use. They tend to fail after 10 to 15 years, and nobody is willing to repair them. Manufactures don't support those products because either no more parts in stock. Wanting to sell new models or technology has moved on and no point fixing the old one anymore. Not all of them fail of course, but enough of them fail to cause problems.
@@angela-gilbert Its true but I think the discussion here as not based on surround receivers but just 2 channel audio - ie comparing the cambridge and Yamaha. Usually on surround systems the failure is often on the HDMI boards which have chips that do decoding that run quite hot. Just saying. On 2 channel as discussed, its likely not an issue :)
@@svtcontour epom also is the problem with logic control. The less complicated unit it seems there is less issue. I have seen many surround receiver and two channel integrated amp failed because of the epom. Some of them can be reset but still have to be done by a technician. That is if the manufacture allows that to happen. In the case of Cambridge Audio and also Pioneer and other company alike. They don't have any distribution in Canada anymore. If one of their units has an epom issue, we have to send it to the USA. In both the Cambridge Audio and Pioneer they are in New Jersey if I am not mistaken. Quite often the shipping cost alone is very close to the unit cost. Have seen two Cambridge Audio amp happen that way in the past year. Both units were from one dealer.
@@angela-gilbert Ya it can happen as well but so far I've only been unlucky with HDMI board failures in my old surround receivers (Denon and Pioneer - but not Yamaha interestingly enough). I guess with surround receivers, its almost ok because often there are new codecs and formats to support and when they fail people are like, well I wanted "X" feature anyway I guess so getting a new one :) But ya as far as 2 channel. So far its been smooth sailings for me. Old school or newer.
@@svtcontour Keep the finger cross. Seems you have pretty good luck. It is matter of statistic. Because I am in the game, I see more than the general consumer. No where near as much as a repair technician but enough to know there is a issue to be concerned.

Make total sense.

Not the most transparent but the most musical and enjoyable. What does that tell you? 🙂 I think you get it.
You guys would be blast to hang out with. :)
Then why aren't you coming? I know I know, you are probably too far away.
Love this
Great explanation.
There are more. This video only touched the surface.
i really like all your thoughts with those controls, yeah i prefered mechanical controls

Yes, you can buy a AS801 with mod done. Contact Mike Woodcock at Absolutely Sound. Their contact info is in the description.
@@angela-gilbert thank you
We live in a world where we keep re-inveniting the wheel.

sounds more emotional than logical

He tries sometime.......... 🙂

The type of logic that doesn't need repair. 🙂
@@angela-gilbert logic is a byproduct of a fixed viewpoint...oh my, somewhat contradictory...sending love to everyone...
