A temporary setup so that I can compare these 2 amps easily. Both are hooked up to Yggdrasil. One via RCA, the other via xlr balanced cable.

I wouldn't term the Alpha 907MR as strictly neutral. There's still a very slight hint of warm but that is great. It's faster and more agile. Micro details abounds more and there's superb instruments separation. Bass is tighter and with more precision impact.

Overall I definitely prefer the Alpha 907MR but it's a madness 33 kgs. At some point I'll have to move it back to the lounge because what it did to my speakers is a revelation.

The 907MR has repaid me tenfold when I connected the Axis Voicebox S. I am a very happy man now. Never mind that it's black and gold.

I feel like I'm in a studio. The clarity is astounding.

Wish those things would't cost over 2 grand here, right now it seems to be like unobtainium here, it costs more used than new.

I am very happy for you UntilThen, and a little envious also, but for all of you that already owns very good vintage, dont be....The result of all that makes quality sound is not only the quality of the amplifier but also all the others elements linked in the stereo system ,including the electrical grid of the room and the house, I dont even speak of the speakers particular voicing or the room treatment... Then dont kill yourself at reading others extasy and think about tweaks and modifications of your own audio gear to makes that optimal.... For me with my Sansui AU-7700 and the tweakes I implemented in my system I enjoy tubelike sound with all possible details in the limit of my own system...Even with that I am jealous for sure of the beauty of this Alpha Sansui... Congratulations to UntilThen !

I humbly accept all the congratulations because this has been a very lucky purchase for me. To import a similar unit from Japan with shipping and import duties would have cost me 3 to 3.5 grand Aussie dollars. I got this for $1800 and it's in immaculate condition. Had I slept in that morning, I would have miss this. Someone would have bought it for sure.

When I went to pick it up, I ask the seller if the headphone jack works. He told me he doesn't use headphones so cannot guarantee if it works. When I brought it home, the headphone function works like a charm. There's no noise at all.

What's more, he had just send it in to a HiFi shop to have it serviced.

So now I have to colour my HD800 to match it.

I vouch to never sleep all morning now and wait for the god of luck to place one on my road!

Someday I'll have to go back and listen to his Sansui Pre C2301 and Power B2301. He showed me the units but I didn't have time to have him set it up for a listen. That's a 300wpc monster.

...and a vintage TV to boot.

Actually, that is a cheap Ilo TV. Not as vintage as it looks. Has an HDTV tuner in it but reproduces only 480i. Hope to get a flat screen at some point.

Glad to hear of another good restoration place in my neck of the woods. Thank you for posting the name.

I LOVE the Sansui blackout look................

Modified my SX-1250 with a an IEC inlet. Now I can change out power cords at will. Have fitted it with one of my home brew monster power cords that I used to use with my Rowland amps. I do believe I am hearing deeper bass.

The latest score...............got these Cerwin Vega DX-5's, a couple subs (JBL!) and a few donateable (is that a word?) mid-90's Sony separates (CD player, receiver, cassette deck) for a great price. Had the rubber surrounds replaced by my local speaker guru and put the speakers in the main system. Cabinets are as close to perfect as I have seen on a 20 year old pair of speakers, as was all the other equipment. Many love CV speaker, many don't..............I do. Have a pair of DX-3's in the garage gym system and four bookshelf sized CV's in use around the house and outside by the hot tub - I am a fan of Cerwin Vega and have been since my roommate had a pair in our rental house back in the day.
