MOSFET power amps, are they more or less sonic equals?

[62vauxhall]

That's how conditioning (brainwashing) begins. With rational, reasonable and acceptable "suggestions". (At least with a few of the women I've known. )

Having lived alone for 25 years then becoming involved in a houshold with the woman in charge takes getting used to. I've never had anyone question my predilections for a long time. I became dissatisfied with my habits and surroundings and really wanted a change but I brought those habits with me. She is trying to fortify my expressed resolve to change but it's an old dog / new tricks scenario.

My advice is to get rid of gear you are not using, other than, perhaps, one spare set that you keep in a closet (that is, one amplifier or receiver, one pair of speakers, etc., just enough for one system and no more). Think about which pieces of gear you really like (it can help to think about why you like what you like, as you may change your mind when you think about why it is that you are wanting to keep a particular thing). Just keep the stuff you really like best, and get rid of the rest.

If you go with the mindset that you want to keep everything that is good, you will end up being a hoarder and not be able to walk through your house. Except, in your present case, you would be evicted.

Of course, you are free to ignore any and all advice you get online. Ask yourself, which advice is good and which isn't? Which course of action will make you most happy, all things considered?

You have said that you want to change. Do you really want to do that or not? If you really want to change, then do so.

I know it is hard to get rid of things that you like. I have too much gear myself. Although sometimes I start to feel regret about getting rid of something good that I sold, I stop feeling that way when I think about the stuff I have and what my home would be like if I never got rid of anything that is interesting. Although I understand the desire to collect things, there is no way I could have all of the interesting equipment that has been made, and trying to have it all would make my life worse, not better. Too much clutter is not good. And you can only properly listen to one system at a time, so having a bunch of extra gear is not really useful.

I have gear stowed in the kitchen cabinets ... y'all are lightweights.

 

[BilboBaggins]

One possible solution is to store the gear you aren’t sure of for about six months. Then revisit your decision and adjust if needed.

 

[Pio1980]

American made gear like the Hafler tends to be sturdier built, simpler, more straightforward and easier to service and keep running than other examples. Common stuff like this has prolific documentation, and the OEM versions sounded good enough for the price to sell widely.

 

[sturgus]

Maybe you can donate it and give the gift of music to someone. If not sell it and give the proceeds to charity of your choice.
I like this one although there are many.

I hope this new direction works out well for you. But who knows how things might play out, in six months time (or more, or less) you may be back to your solo ways that you have become comfortable with over the years, and wondering wtf you were thinking today. I don't know what other gear is currently "under scrutiny", but that particular Sanyo amp is highly regarded from what I have read, and those don't fall out of the sky everyday.

MOSFETs are a compromise compared to what? Tubes or BJTs or JFETs? I personally think BJTs are the biggest compromise. About the only big failing of tubes is that they're low current, high impedance devices. FETs have response similar to tubes and don't require a complicated coupling scheme. My stereo's entire signal path is made of JFETs and MOSFETs and it sounds excellent. BJTs are about my last choice for audio gain devices. BJTs are the compromise, not tubes or FETs.

If one buys and keeps everything that is highly regarded, one will end up a hoarder without being able to walk through one's home with so much gear stacked from floor to ceiling. Unless you have a warehouse, you need to not buy and keep everything that is "highly regarded."

I resemble that! Its a sickness for sure.

I will say, the Sanyo plus series were special but uber rare in my parts. I've never seen another plus receiver, except on Ebay. I always thought my P75 had about the cleanest, tightest uncolored bass I'd heard, and we used to drag equipment around and compare a lot. I just re-read the review in January 1980 Stereo Review, and they produced 136 wpc at clipping. They don't have the name, and they are a bear to work on, some parts near impossible to get, but in a head-to-head, they are more than formidable. For the OPs purpose, a Hafler is going to have more street cred from the typical guest. But for the collector, you will definitely surprise and raise eye brows with one of these in good working order.

The subject of the original post is one amp that occupies approximately one square foot of space. Not a warehouse full, or anything "stacked from floor to ceiling".

Things deviated when I informed of the change to my living and/or lifestyle situation.

You should reread the opening post, as it is about more than just that one amplifier; that one amplifier is just one of many things:

...

One of my new housemates, (she who owns the house) is encouraging me to divest myself of nonessentials, suplus paraphanalia, things I am not using therefore do not need so this Plus P55 has come under scrutiny.

...

 

[Pyrrho]

Possibly, being pressured by a lady friend to ditch the hifi resonated with parts of the crowd here?

My experience is that lady friends never like the look of a hifi system. If they care for you, they may be diplomatic about it. If they want you to get rid of it, it's only the start of things to come.

It depends. My wife is fine with having a good system or two; in fact, she likes having a couple of good systems. She is okay with me having a few extra pieces of gear, provided there is room for it somewhere. But what she would not be okay with is me hoarding gear when there isn't a proper place to put it. I don't think my wife is the only woman like that.

And you should re-read the OP's sentence that you quoted. This thread is about one amplifier. You are projecting your own experiences

Others have suggested that the OP should consider keeping the Sanyo, it's not just me. You posted your thoughts in this thread before I did, and I accepted that your opinions did not align with mine. Please accept that my opinion is different from yours. This is nothing to fight over. There is no right and no wrong here. Allow the OP to consider a range of view points and make his decisions as he sees best. Nothing is going to be decided by you or me.

 

[Chicken-01]

I own 2. ADCOM Gfe5300’s. And they are in the closet..no power compared to my other amps..
I traded a PIONEER sg 9500? ( I think was the model #) I want my eq back !!!!
Don’t know why, must be the VU. Meters but these are my amps of preference

 

[Chicken-01]

Not me

 

[GChief]

Is Chicken OP?

If you go to the first page of the thread you can find out.

Original post quoted below. Only the last few sentences shown because that is where the actual request for opinions on the performance of the Sanyo Plus P55 occurred. No other questions were asked in the original post.

......

I need A/B comparisons to notice a difference between amplifiers. My ability to remember what one sounded like a few minutes after hearing it is poor. If a Plus P55 performed similarly to a DH-220, I could make a case for keeping it.

Looking for opinions as those are the only MOSFET amplifiers I've owned.
