Xin SuperMicro-IV VS RSA Tomahawk Impressions - Page 3

post #31 of 119
Latest thing I have noticed is that if I bump the amp I hear a high pitch sound. After a couple of seconds it goes away. Wonder what this could be, I will email Todd to see if he has heard anything regarding this. Otherwise the amp continues to burn in.

I was thinking of a hardwood like teaque...I think that's how you spell it

I found some great little hardwood boxes with a sliding lid that would just fit everything inside. With some modification I think it would be very unique.

Zebrawood would be cool too! That crossed my mind. But we'll see what I can find when I finally get my SMIV.

Fine, a plastic- or wood-lined metal case. Insulation inside, protection outside!

Thanks ALL of you.

I have to remove the last pic because it is not my place to openly advertise the innards of SMIV (my Panasonic LUMIX DMC-LX2 camera is HIGHLY resolving and that photo is as clear as the real thing). Dr Xin himself never revealed the board, at least not on so clear a photo. I know I am being paranoid but if somebody wants to imitate Xin's design let them attempt to do so, but it will not from my photos. Xin worked hard, really hard to get his amps as good as they are today - to some extent that he received vehemenous remarks for secluding himself in his effort to improve his amps.


Oh yes, as sted above my Xin only had less than 48 hours of burn in when I compared it with my TH. My TH has near to 700hours.

And the black case was available back in December 2006 when I placed the order. I guess Xin has reserved the black case for me all this while.

And it was not easy to pry open the amp from the case because there's two double-sided gummy underneath to hold them in place. It is nerve wrecking to pry open. You will have to use a small screwdriver to pry it loose bit by bit.



* And another thing I would like to add. SMIV is even more transparent to how the songs are being recorderd. For example, I was listening to The Breeders "Last Splash" and I have to adjust the volume knob almost every songs because the album was badly mastered - soundstage was dissapointing with this album (an Audiphile nightmare), then after the last song in the album has finished, The Clash "London Calling" Remastered Edition was next in the queue, BANG!!!! suddenly there's huge openess and blissful audio experience. This shows how responsive SMIV is to the condition of the source.

EFN, it would be lovely if you tried some giant killers like the stax sr001, comparing them to the ER4S+Xin amp. It would be a fantastic battle, the stax are regarded as on of the greatest bargains, sq-wise. A clash between them and the great sinergy of supermicro-er4s would be of great information for many headfiers (some could even decide to stop their upgrade syndrome to xin-etys, depending on the results of this comparison).

GREAT review, anyways!

Aaah that will have to wait until I have the budget




Anyway, burn in update for SMIV. Now nearing to 60 hours (3 alkalines depleted). SMIV has totally outclassed my TH in Soundstage department. Previously under 50 hours, SMIV has only slight advantage over TH soundstage, but now it's really wide and spacious - AMAZING.

Yes I have put up my TH for sale locally here in Malaysia. If I can't get someone to buy it there then I will put it up for International sale via Head-Fi. Sad to see her go but SMIV is sooo seductive

I would love to keep both but I don't believe in stacking up my gadgets to collect dust. I only keep the ones I use.

It's funny to see you addressing the tomahawk using "her".
However I'm happy to have ordered a Supermicro some days ago. Let's see how much time will it take for "him" to arrive

YES! between the two, I can identify at least 3 things SMIV does better than a TH on SQ alone (with ER-4S in mind). That tiny thing defies everything that the look projected.

how many hours is your th burned in?

anyways, after reading your review, i'm eager to receive my supermicro (ordered in jan 07). i love the th, and if the micro can present a better sq, then i will be in heaven!
