Besides The SR-71, Best All Around Portable Amp - Page 3

post #31 of 207
gpalmer,

thanks for the headsup, ill look into it
post #32 of 207
with my ipod mini with 128decode And the shure e2's the two amps were the same.

in the club using the output of the dj mixer from a denon dual cdp the sr-71 seemed more relaxed, less fatgue i guess
(also the I kept hitting the switchs on the sm everytime I needed to adjust the volume...pain in the butt...but that was personal and being used not where on may intend to)

the g08 in line...
the sr-71 stood easily and the sm was a joke

I tell you, all you guys got me looking deep in my wallet for some extra loot. Even though I am mainly a portable iPod user, I will most definetly be building my home rig soon. Should have never sold my old Carver equipment, and Systemdek Turtable. Sure miss that Carver pre-amp.

also in the jacuzzi with the d-ej2000 and shure e2's the sr-71 was easily noticably better....also really laid back more.

then again thats not a real test but just telling you that I did give the sm every chance..the ipod it was perfect but anything is where she fell apart.

I am a big time source believer so..

In the past two months I had some chances to compare a SM3 (NE5534's without feature switches) to some high-end DIY/commercial home headamps. To my surprise, SM3 holds its own pretty well, if not better than those much bigger/more expensive ones. It's interesting to see some negative impressions on SM3 here, but so far, I am very happy with my SM3 and continue to be impressed with higher-end sources. The only headphones that I found SM3 can not dirve well is K1000. Whenever the volume goes past 1:00 clock, much distortion came in.

The K1000 would be a hard load to drive. Have you tried it with more buffers? I have four buffers in a V3 and I wonder how much this will change it drive capabilities (four buffers per channel).

Xin has said to me that for high impedance, low sesitivity 'phones like K1000, HA-5002 would be able to swing more voltage than Buf634. I wonder if I can convince him to stack HA-5002 x4 for me and my K1000.

With my "nude" modded K1000, I get a couple more dB's of effective sensitivity, and SMv.3 w/ Buf634 x2/channel CAN drive it with great sound, but not when real rocking is called for.

But What About the Charge Issue?

I'm suprised that nobody in this thread has commented that the SM3 last about ten times longer on its battery power than the SR-71. Not to mention that the AAA's can re-charge while in the amp (I think).

(I have neither amp, so I can be considered neutral on this issue.)

to bhd812- how exactly do you find the supermacro to be a joke (or completely subpar in comparison to the sr-71)?

But hey w/e the kiddies like these days is all good with me, just not my cup of coffee...or on the same level as I think of the sm after a long (I was really bored) listen maybe I should say it's just not my type of Capri sun juice box....you know the drink all the kiddies drink while their at school..
i can understand there was some fanboy-ism in that but...

Back on topic:
The supermacro has a lot of additional features (bass boost, auto-off timer, battery/DC powered, internal charging (as mentioned below), impedance switch, crossfeed , LOTS of additional options on opamps, buffers, etc. that the sr-71 simply doesn't offer. The ability to tailor the amp to ones needs is, i think, an important factor in choosing an amp.

You might be confusing amps. The SR-71 has about a 40 hour battery life on a set of batteries, and if Xin's managed to get 400 hours of run time out of the SM3, I'll fly back to California just to kiss his @)(#! (And it doesn't even have to be washed)

I don't have my HR-2 here right now so I can't compare them right now, but I did spend an hour or two comparing them on Ray's switchbox in SoCal and they were very, very close. I think there is a slight difference between them but it's so small I doubt if you could tell it was there unless you were directly comparing the amplifers and I'm pretty sure I couldn't pick them out reliably in a blind test, so I'd pretty much agree with him...

gpalmer, when I was considering buying the SR-71, I had concerns about it's battery power (not to mention that you have to remove the batteries when it runs down). In a private message, another head-fier told me that he/she got only 12 hours battery life from the SR-71. I can't remember exactly whast most people get from the SM3, but I recall that it was over 50 or 60 hours. Perhaps I exaggerated before, but I am very surpised to hear that you get 40 hours on your SR-71. Is that with rechargeables? If not, then having to keep buying two 9 V batteries must get expensive.

Do others get that much battery life from their SR-71's? How about from their SM3's?
post #43 of 207
That's with Duracell's and is Ray's figure I haven't meaasured it personally since I'm still working on my first set of 9 volts. I haven't tried using rechargeable's yet. It sounds like the member might have been using low capacity rechargeables with the SR-71 which would sure hurt it. The 9 volt rechargeables are pretty primitive technology wise still since they don't get the use the AA and AAA do. I haven't paid much attention to the SM3's battery life, I see Xin is claiming 60 hours but in general I take Xin's claims with a grain of salt because of past experience. Then to compete sound wise, you would have to bias the SM3 into Class A which would probably cut the battery life in half and use a better op amp (read drains more current) and in no time you have the same effective battery life...

A new player?

Looks interesting dunnnit? And if it maintains the sound of the Rudistor lineup then it might be something special.

That NKK-01 looks like it's going to tumble over face first from the weight of the knob Guess that's why the headphone jack is in front!
