THE INTRUDER by RSA. balanced dac/amp. . Update available for even better sound. Just pay shipping.

post #1 of 578
Thread Starter 

I received the Intruder today. I have to admit that using its cousin, the 71b, I was expecting great sound and since the form factor is the same, was curious how the Intruder would stack up with the same size case and now incorporating USB. To start right off, I have never been a big fan of USB listening, but my mind has changed, now.

 

Since this Intruder needs time to burn in, so will my impressions go as the Intruder may or may not change with time. I can say right now with maybe 5 hours of time on the unit that it has tremendous impact, transparency and a subterranean bass. There are a number of phones I need to try out but so far, authority is what first strikes me along with clean insightful impact of musical delivery. 

 

Wanting to listen via one of my favorite sources, the iRiver H140, I was a little surprised. Why I wondered, is it not as good as the usb. I am using the line out . . . . oh wait, I am hearing the difference of dacs and while my iRiver is modified with excellent caps, and I enjoy the sound, it can not touch the sound of the dacs inside of the Intruder. A source with USB out or a newer and better dac than the iRiver will serve the Intruder and your listening well. For this I tried the DX100 as a source. Wow, now this is a combination. The amp of the Intruder is truly excellent.

 

The bass delivery of this combo is amazing and awe inspiring.

 

Detail is very evident with the Intruder. It is not etched or just noise but the detail with nuances, which adds to the listening pleasure. You don't feel like you are missing something in the upper frequencies.

 

While the Intruder does not cover up grain or poor treble, it sure doesn't add to any. Very smooth, extended and wonderful in the high range. I love the full bodied midrange that neither jumps forward or is recessed. Listening to the good cuts (there are some too canned sounding) on Dwight Yoakam's, Accoustical recording, the guitar and voice come across so natural and immediate.

 

So far the mids are very neutral but natural. The male and female voice is inviting. When harmonies are done, there is enough separation that you can tell that there are individual voices. That that occupy distinct space. Guitar in the mids is not harsh or warm but clean and melodic, if played that way, as in Hell Freezes Over, "Love will keep us alive" by the Eagles. The bass lines are very to follow in this recording as well, providing a solid foundation. 

 

More to follow.

 

I have posted this in the source section as the Intruder to me falls more under the source/amp than purely amp section.

Agree, this is probably the better place to give feedback on the Intruder.

 

Many thanks for your feedback so far, look forward to more of your impressions while I await mine to ship in around 10 days time.

Well with 24 hours on the unit, and a previous bit of rough music, the sound is very nicely detailed. Not edgy but natural adding to the overall impression of live music on well recorded live sound. On studio mixes the sound is also very fine, with a very nice wide and deep, not just one but both, sound stage, when well recorded. I notice a nice layering of sound and is very focused.

Jama, when your review is ready, could you please include differences between the SR-71B & the Intruder? I have to admit I'm not a SR-71B although a bigger fan of the Predator. I'm curious if the Intruder has improved on the SR-71B (esp in the tightness and clarity in the bass).

Interesting, I have always enjoyed the 71b. I will say at this point the Intruder is a little different sounding. It has a tremendous bass impact but very, very solid and it goes very low. The transparency and clarity is remarkable but natural. In these areas, I guess you could say it is better or different but to me, at this point, it is noticeable. With each phone I try, they really come to life. One thing I notice is a very wide and deep sound stage but not distractingly so, just an out of head large sound spectrum with what sounds like all the decay that was recorded and not truncated at all.

I don't know. I have no details about that or the other chips.

Could you please try it with Foobar and use WASAPI to play any 24/192 file? It would tell immediately the result.
