well my thought process is that the sr-71b is $650.00 and the intruder is $700.00 i would say logic would tell you one of 2 things, the dac section is a 50.00 dac section OR they are split between the dac and amp being $350.00 for dac and $350.00 for the amp.

 

in my observation i would expect that a dedicated amp that is $650.00 is going to be more complex in its hardware and circuitry ie: mono quad balanced output. and having the kind of power its capable of putting out.

 

thats just logic observation, i could be wrong but it makes sense to me

So, we're actually saying the same thing.

essentially yes. i think its kinda gimmicky though, becuase people perceive the intruder to be better because more expensive has to be better right? thats the line of thought most people have.

 

rerading on rays site, the intruder mentions nothing about quad mono balanced, balanced output. however the sr-71b does.

 

egh either way i really enjoy my 71b its a phenomenal asmplifier

The SR-71B has clearly more advanced amp section compared to the Intruder. 

 

The amp section in the Intruder has less hardware: 

- price wise they are (almost) the same: the price of the DAC section comes at a cost - it's certainly not 50US - as you guys pointed out

- Ray never mentioned the details of it: if it was the same as the SR-71B he would have advertised it for sure

 

But the most important is how they sound right ? :) the sound sig is very close according to Ray. I'd go for the SR-71B as i have already a portable DAC. Looking forward to it :dt880smile:

i was just generalizing, if both amps are somewhat the same but one is 50.00 more with a dac section and supposed to be better amp section for 50.00 more clearly the intruder would be the pick of the litter however i agree with you, its not a 50.00 dac section, but theres no way that both amps almost cost the same but one is better than another and offers more ie: intruder

 

i too use my own external dac ibasso db2 with my sr-71b and love the both together

Do you use them in balanced mode?

yes i have a toxic silver poison cable balanced (for my w4r) and a whiplash twag 2 eclipse balanced (for my se535) then i have a Balanced RSA male to Balanced Ibasso hirose male Toxic Silver poison cable, completely balanced.

 

personally i found there to be a big difference between single ended and balanced, but it stired up a bunch of worms on another thread about what i thought the benifits of balanced were.:rolleyes:

Sometimes balanced doesn't sound much different than single ended which is just as good, except for a little more power in balanced mode (ZDT, EF6, HiFi-M8). But with the SR-71b the single ended output is a little darker and less spacious sounding, and definitely a bit less powerful than balanced. It's just because of the way the amp is designed I guess.

This is why the new F-35 Lightning makes sense - it's got incredible punch and power with a similar spacious and open sound as the SR-71b, but in a smaller form factor because there doesn't need to be room for a 1/8" jack on the front. I need to get more details on the F-35, which sounds fantastic .

Well, let us know if you have more info; am interested!

I am looking for a Balanced portable AMP to go with my JH Roxane and my "may be to come" AK240 DAP that has a Balanced (clean ??) LO  (today I have a RWAK100).

 

But, I must say that I am lost in the RaySamuel Range !  Just for portable Balanced Amps, he offers 4 amps: "The intruder", "the Lightning", "SR-71b" & "The Predator" !!  

 

 

- So, Is the SR-71b still the BEST of this line of Balanced Amps ? Isn't the NEW F-35 Lightning better (as Balanced only) ?

 

- Also, I can't find it's output Impedance ! So is it OK with very low impedance IEM like the 15 ohm JH Roxane that I have on order ?  

 

- The SR-71b is not new ! Are there now on the market other better portable balanced Amps

 

thanks in advance

IMO the 71b is the best, i love love love love love mine, yes it is great for very low or very high output impedance headphones, for instance i use my se535 which are considered sensitive, and then i use my 100ohm etymotic er4pt, low gain on 535 high on er4pt perfecto.

I love my f-35 paired with rwak120-b. It's the perfect size for the ak120

Ray makes some incredible amps that can drive sensitive iems like my jh16s with ZERO hiss and Just as easily, my LCD-X and LCD-2

I had the rxmk3-b+ for a wile but returned it cause I couldn't stand the hiss on my 16s.

If you are not going to use single ended, consider the f-35

If you are considering a solid investment in your musical enjoyment and incredible service, Rays amps are the way to go. When a violin sounds like a violin, how do you improve on that?

post #194 of 223

So SR71b is better than ALO MK3b ?

 

And anyone knows the full spec of SR71b (with intruder spec update) like ALO on their website ?

 

ALO Rx Mk3-b+

Gain : low/med/high = -3dB, +3dB and +12dB

Output Power (Balanced) : 32Ω -> 640mW , 50Ω -> 630mW, 300Ω -> 150mW, 600Ω -> 80mW

Output Power (Single Ended) : 32Ω -> 320mW, 50Ω -> 220mW, 300Ω -> 40, 600Ω -> 20mW

Ray Samuels SR71b

Gain : low/med/high = ???

Output Power (Balanced) : 32Ω -> ???, 50Ω -> ???, 300Ω -> ???, 600Ω -> ???

Output Power (Single Ended) : 32Ω -> ???, 50Ω -> ???, 300Ω -> 40, 600Ω -> ???

I have an SR71b and was very interested in hearing the ALO options.  After reading enough reviews that mentioned hiss with the ALO's I lost interest.  Background hiss is a pet peeve of mine and the SR71b has zero hiss.
