Very cool video. Full of passion and very entertaining at the same time!

Thanks for the great presentation and education. I always lean something from you and appreciate your time and knowledge and dissecting the internals of amplifiers that provide the grunt and magic we all enjoy. I've been an audiophile/music lover since the 70's back when I had the large Advent Loudspeakers driven by a Crown amplifier. Still remember those great sounds, for that time.

Hi? do you have any experience with Musical Innovation amps and pre-amps. They are made in Norway by a very very very small company. The value of those amps is second to none. The typical high power ab designs newer worked out for me. Imo amps under 50w pr channel output is always best for sound quality.

Yep, though there is differences in level of gear that has also stayed consistent.

I've been watching the switching supplies. From personal experience, some of the early audio implementations were very bad. The first I ran into were Sony. Sony introduced a line using them in the '70's. I was doing an amp roadshow at the time. Travelling doing a "High Speed Clinic" from city to city at those actual retail audio stores that existed. It was advertise to bring in what ever amp, integrated, receiver, ... you had and I'd provide a report on it's "Speed". Rise time and Slew rate of a 10Khz squarewave at full rated power into 8ohms. After the 3rd in a row Sony switched PS smoked, I stopped allowing them. It was the only brand I had that problem with. Many produced shitty looking outputs, but survived.

@@OCDHIFiGuy would be interesting subject though

Those prices are nuts. I have a Samson Power Amp with a huge toroidal transformer, giant PS Caps, and discreet power transistors on cooled rails. 600 WPC full bandwidth power @ 20Hz-50KHz at maximum distortion of .04% at full power! It is a class A/B. It cost me $400 dollars brand new back in the day and still works and sound amazing! Guys that charge more than $1,000 for an amp with less than 500 watts mono or per channel are just ripping people off because there are idiots out there that will pay premium prices for circuits that are simple and were designed in the 1950's. There is no "Magic" to building high quality Class A or A/B Amps at all.

Hi Mikey I had a great experience at the very recent Sydney Hifi show listening to the Vitus integrated amp with Audio Soulutions Vigaro 2 speakers. Plus hearing the Gal nitrate amps you talk about. I also engoyed the Soulnote A3 if i have my model numbers right. The amp here has 120 watts per channel into 8 ohms. The disortion figures were nothing amazing either .027 for memory...but this setup had clarity and impact. The speakers deliverd stacks of clean deep hass from only 4x 6.5inch drivers. $15000 isnt mega dollars for a great speaker i dont think. Im sure you Fisher and Fisher speakers are great too. Other high profile companies are probably glad these speakers are not of higher profile. Besides the million dollar system featuing Duntech Halcro and Dohmann turntable. Plus Ypsilon and Cessaro. This system took things to the next level. The dynamics and clarity etc were incredible. Some other very high profile stuff was a little underwhelming in comparison.

@OCDHIFiGuy yeah agree 💯 percent. As much as I love my records and buy too many on a smallish wage I do really see the beauty of streaming....that way I discovered new music...some way older now that I missed then I can jump straight onto Tidal and enjoy. Then hopefully find the cd or the record. Many older titles are hard to find now and when you do can be very expensive. I am a big and new fan of Caroline Polachek...check that song Billions out. Lots going on in that mix wuth some killer bass too. Also I like the mad professor types super passionate about their gear. As you know it costs heaps to exhibit today. Even 21 years ago when a late mate and I did Vegas Alexis Park it cost bags. My friend had a small brand Hollmann Audio we had two pairs of speakers one pair all vintage jbl driver in a 3 box system and a tall floorstanding speaker 3 way with Dynaudio and peerless drivers. I still run these today. Like a cheaper Duntech without the time alignment that is very important. Love what you bring Mikey.

He may have been involved with B&K for awhile, too. Circuit topology resembled Dynaco and Hafler which were higher value American brands. Before going to engineering school, I learned much from building kits from Dynaco and Hafler who made many Class AB amps.

You noticed, huh ? I didn't share the part where I emailed my amp pic to Flemming. The founder of Gryphon... I think he liked it..

i think altec lansing was one of the best ever brands as my fathers studio in 1970 had big monitor speakers and after he bought JBL being the L for Lansing , lucky to work with such great names from hi-fi industry or owned their company , i think the main problem as it happened with American and European brands was the low cost of production of japanese brands and copying all the work done by european and american engeniers and then sell it at low price , but i remenber when there were still some european brands as american ones still important in the hi-fi or sound business, the quality was over without a doubt but the finishings start to look cheap as some brands i tested when younger that looked very minimal but quality wise above any japanese brand , i remenber especifically a cassette deck from Blaupunkt the most simple one can imagine one row of leds only to adjust the rec level but the sound quality was amazing good as some 79 philips cassette decks(F series) that looked good and modern in 79 and had a super quality of sound and expensive materials built and next year were the same but all built with plastic and the sound wasn´t there but owning Grundig i remenber some decks ,two head decks that were over later calibration 3 head decks quality of sound from japan as crown from the 70´s power and pre-amplifier were amazing good with JBL speakers and big ones and SAE i have still a cassette deck maybe from 81 that had a receiver with great quality of sound to wich i had cerwin-vega speakers, but all components were black with a nice blue display , i also remenber in the 80´s brands like Sony or Pioneer to sell in the U.K had to have better specifications than in other european countries mostly speakers, english brands had superiority, as in the 90´s i bought a ES Sony integrated amplifier that sounded amazing even the phono input had a superior sound quality and was really heavy but i sold it and a few years ago i looked for one as mine on Ebay and found several but in hifi engine manuals i noticed that they said ,this specifications are only to the amplifiers sold in Portugal and U.K , wich is strange ,for me the 90´s were yesterday as we grow old it seems the years pass very fast, People talk about nakamichi and having a father who was into music and sound quality he owned a big colection of nakamichi components since 1974 till late 90´s they do work well but if you don´t use them that much or all start to work very bad, i remenber buying the dragon when released ,it cost me 700 dollars at the time wich was a lot but i choose it because i couldn´t aford the Teac-Z-7000 and in the first days i thought i had a very good deck this in january of 1983 and by August i stoped it or it had been ruined and sold it , the heat destroys them and by that time one used to record and hear a lot of cassettes, and several times in hi-fi magazines after tested wasn´t even as good as other top decks from several brands but like sting said "history will teach us nothing " and again people talk like nakamichi is the better brand of cassette decks and lucky for the ones who have them, i had all top models working at a 100% already sold 3 of them and received 30.000€´s as i had already mine and still like them like the 680 ZX and the 700ZXL and the cassette deck 1 and the best of all in building quality the BX-2 still working, as all others were repaired for a lot of money by a old nakamichi technician in England. This to say that it´s expensive to keep a brand production in Europe and U.S.A. but quality wise japanese did not made anything better , just have a low cost of production and now they own the market making new components from the cheapest materials and engines they can find, i forget to refer HH scott, which had great quality hi-fi system ,i went to L.A. with a friend in 1978 to buy american built cars that were looked for in Europe and hard to find so for maybe 10 years we filled our pockets with money but the first trip in 78 my dutch friend bought a top of that year catalog integrated amplifier from HH Scott and still today it works with perfect sound but earlier intime i can´t remenber that if belonged to my grandfather or my father but a amplifier looking very old but what a sound ,it´s still a tube amp but by the looks it doesn´t seem that good ,when conected the sound is perfect and it´s a 60´s model, i tried it with JBL speakers ,than with Mission and tannoy also and put a 70´s turntable the SL-1000MKII from technics and a bought recentelly P10 from Rega both sounded like they never had sounded, no matter what speakers were conected and we are talking about a looking like trash tube amplifier from the 60´s american made and i fiorget to refer we conected some philips speakers that were from my first pioneer system in my bedroom and they look bad and very old but when conected ,i couldn´t believe the sound coming from them and i had them stoped maybe since 1973 when i went to Africa to work and after that i think it was the first time i conected them and some say ,hum!japanese how good can it get? they never heard about european or american brands who were the best and still work with quality after almost 60 years
