Transients hurting my ears on hifi solid state amps

I took a look at the specs for your existing amplifier and the proposed Pass and Luxman, as well as those for your speakers. I have concerns that any of these amplifiers will properly drive your speakers which are 4 ohm and recommend 40-200 watts to drive them. I had suggested in an earlier post that Class A might solve your problem, but sole focus on Class A at the expense of the necessary power depth might result in a less engaging system. 

I had suggested that you consider class AB solid state amps with high bias to class A, I still think this is worth exploring. I suggested the Coda #8, with up to18 watts of class A, simply because I have experience with it, I am sure there are other good options. 

Your speakers need some horsepower, I would be wary of going too low just to satisfy the class A desire.

Since the OP is referring to "transients", could it also not be due to his amplifier using excessive loop negative feedback, which might be causing Transient Intermodulation Distortion?

@atulmajithia What is meant be 'excessive'? Usually the problem is that the amp doesn't have enough feedback, and design concerns make it impossible or impractical to add more. FWIW our class D amp uses about 37dB of feedback and has not problems with brightness of TIM. IOW its all about the design rather than how much feedback is used.

Clarification on my post, the Coda #8 is class AB, and delivers 18 watts of class A, but, is rated at 150w class AB. 

I work from home, and I listen between 8 and 12 hours a day, though most of that is not critical listening.  I am also sensitive to "bright" components.  I currently have 3 turntables, a Herron VTPH-2A phono preamp, and a BAT VK-30SE preamp.  On the digital side, I have a Node 2i and a NAD 5000 CD player, both running into an SMSL VMV D1SE.  My speakers are Magnepan 1.7i.  I can listen all day to any source without fatigue.  I can make a recommendation of a class AB amp that would work for you within your budget.

I'm currently using a Bryston 4B SST2.  I find it fatigue free.  If you're lucky, you might be able to get one used under 2k.  However, the 3B SST2 used should be well within your price range, and buying one used, there should be a significant portion of the 20 year warranty left on it.  You should be able to use your current integrated as a preamp and run the pre outs to the external amp.

Thanks for your research. That could indeed be an issue. My theory was that underpowering the speakers to some extent might ensure a softer sound with less of this to me transient-related problems. I also know that power rating is not everything and that tube amps, and to a somewhat lesser extent class A amps, are more powerful that what their rating tells us.

I use my PrimaLuna almost exclusively in triode mode, which is 25W and I enjoy the sound and there's weight and power to the sound in general and bass in particular. However, I do miss things that the more powerful amps could do detail retrieval, projecting the sound into the room and soundstage. The ultralinear mode, which gives you 42W, improves objectively on these aspects, but there's a magic and to me a more engaging sound that comes with the triode mode that I miss and I always end up going back that mode.

I also don't necessarily consider these to be speakers that will be with me for many years to come, so I could accept having an amp that isn't a perfect match for a while until I have the budget to upgrade the speakers.

However, I would like to be at least not limited to low-powered amplifier. One of my main worries is that as you go up to better amplifiers, the power rating usually goes up too, class A (and tubes) being the exception. I still struggle to identify amplifiers that could work for me irrespective of their power rating and any help on this is welcome.

class AB solid state amps with high bias to class A

Does this simply mean amps where after X watts, it switches from A to AB? This type of amplifier could be a great solution and the Arcam, even though I had issues with it, had something that I really enjoyed and it used what they call class G, but is basically A/AB in my understanding. I'm trying to stretch my budget, but the Coda is quite expensive, especially when factoring in the preamp cost, and I would prefer an integrated. Are there any other suggestions for this type of amps?
