Technics SU-v75

mlistens03mlistens03 Posts: 1,213
Hey guys,
I just thought I would get your opinions on this integrated. Anyone heard it? Like it? Dislike it?
I’ll find a spec sheet and post it later.
And here is the question of the day, does anyone know if it can drive my LSis? I assume not, as it’s not a powerhouse at 75 wpc, but I thought I would ask. I’ve heard it said there is a difference between high wattage and high current, but I don’t think this is either. It does have a 6 amp draw from the wall though :astonished: , that makes me think that MAYBE... just maybe... it has the current to pull it off.
And your probably wondering, “why isn’t he using his Crown”? Well, to tell you the truth...
it died. It just died. No idea what happened, but the left channel went POP! And now it doesn’t work. I’ve checked everything and the culprit has to be the amp. Can’t find anything obviously wrong with it so we will take it for warranty repair at some point but I dont know when.
Thanks for your help and opinions,
Micah

sure it has a flat response, and sure it has a lot of detail, and yes, it has good and clear lows. But is it enjoyable to listen to? Does it make you grin ear to ear? That’s what really matters.

    No ears on experience with that Technics, but by all appearances I'd say unremarkable at best.

    Except for their high-level, "prosumer" Technics/Panasonic equipment, generally (IMO and FWIW) the consumer-grade Technics/Panasonic hardware is inferior/bland compared to the other massmarket big Japanese brands.

    That’s kinda what I was worried you guys were gonna say. It does sound better than my Yamaha and the Crown on the Mission 770s, and overall is fairly low distortion, and is very dynamic. It seems a little on the warmer side and is a little light on the bass, although that may just be a combination of room placement and speakers that don’t produce a ton of bass. It sounds better than almost everything I’ve ever heard on the Missions (although that’s not saying much).
    I think I’ll probably use it for now, but I am gonna eventually switch back over to the Crown when it works again. Even though it doesn’t sound as good as this on the Missions, the LSis more than make up the difference.

    Yes it’s does, but it’s not blown. And the entire thing would shut down, it is before the transformer. It still turns on and the right channel works ok. I’m gonna take it for warranty repair eventually, just not sure when I’ll have time.
    Edit: sorry thinking of something else, it has a breaker, which I have reset.

    My first stereo had a SU-V98, probably pretty similar. It wasn't garbage, but it wasn't great. Use it these days to power the speaker for my Ruben's Tube in my classroom...

    I've heard of Rubens tubes, but I’ve never actually seen one, that was really cool!
    I did some reading, the SU-v98 was two tiers higher in that line. I believe it was pretty much identical but it came with a better tuner, more power, a little bigger, better transformer, etc.
    Oh well. I haven’t done any real listening to it yet, so I will do some L&R comparisons between the Yamaha and the Technics, and whichever wins gets to stay. I don’t have time now though, so I will report back this afternoon when the tests are done.

    I learned about standing waves after I got a powerful subwoofer.

    Thanks for posting the link. I enjoyed it too. Here's the video for others to see them in action. B)

    I never got around to the left and right comparison of the Yamaha and the Technics, hopefully I’ll be able to do it later when the power stops going in and out (I hate thunderstorms :rage: )
    So, back to one of the original questions, do you guys think that this thing might have a slightest chance to drive the LSi25s? I don’t think it will, but a 6 amp draw from the wall makes me think that maybe... just maybe... it can pull it off. And I don’t mean “will it play music” by the way, I mean “will it blow away the Crown and Yamaha combo, will it become my daily driver (until I get something better, of course)?

    I am doing excellently, thank you very much ;)

    I would just hate to see anyone waste much effort on the titular Technics amplifier, if you catch my drift. :|

    I picked up an SU-V76 for my son who wanted to get into vinyl. Also picked up a pair on infinity speakers. It sounds pretty decent. I could have picked a higher model but I know their active cooling (fan) tends to fail and the chips fry. This one has heat pipes and cooling fins. As long as it has ventilation it should be happy.

    Quick question, do you guys think that the headphone amp in this Technics could drive 300 ohm headphones? The specific headphones in question are Sennheiser HD 600s. I’m trying to look at the money from my gear in other ways so I can best use the money, and I though the I would ask.
    P.S. I am on vacation and this is one of the first times I’ve had WiFi all week, so if I haven’t replied to PMs and people mentioning me, then I apologize.

    No idea really, but probably not terribly well. Not the kind of thing that would have factored highly in the design spec for a massmarket Technics product like that amp, I'd reckon.

    Only one way to find out.

    If you look at the circuit diagram for the Technics amp the headphones and the speaker output are driven by a prepackaged amp IC (SV13205A). These devices, while very convenient for the manufacturer, aren't very good at delivering much current into any load that isn't 8 ohms.
    But, as everyone has suggested, give it a try.

    Glad you tracked that info down, Ken. I dug around a little in googlespace for info on the amp's headphone output before replying but came up empty -- umm -- handed. :/

    Thanks for the help guys, I did some digging myself, except I couldn’t find any info anywhere, and I’m not knowledgeable enough to look at the schematics of the amp and know how it works, so this is really helpful to me, thank you.
    I’m not sure if I’ll be purchasing these headphones, but if I do, I’ll be looking at a headphone amp too I guess.
    Thanks,
