Can it get better?


Seeking the advice of folks who have experienced significant gains when moving from an integrated amp to separate pre and power. I realize there are several threads on the topic but specifically, I’d be concerned about a lateral move in terms of sound quality while dishing out close to 2x what I purchased my integrated for. For example, my system consists of a Pass Labs Int-25 driving Harbeth Shl5+ 40th anniversaries. It’s a combination that gives coherent and smooth sound yet is quite resolving. 
Why change? For one, I would like to experiment with different power for the Harbeths and am intrigued by some of the class d options out there. The Pass was about 5k and some of the pre and power combinations I’m considering would push the cost north of 10k. There are a number of well designed preamps out there in the 5k range that I could see serving me for many years. Assuming good synergy with the power amp, is there good reason to believe that separates would sound significantly better than the little Pass which has system synergy built in? In what way? Or would I have to venture into a higher tier in terms of cost?

thanks for the advice

Thanks for the replies. It's the age old discussion about Harbeth speakers and how much power is required given their relatively low sensitivity. My experience with the Int-25 is that it does check a lot of boxes and perhaps the most important one being able to handle peaks at my average listening levels.

Differently designed amps will have their own character, but I'm wondering if going to separates has a distinct advantage over integrateds in areas that all amps try to achieve like low noise, precise imaging, dynamics, etc.  Like you said Geof, integrated amps are great these days. Is it foolish to think I could achieve a significant Wow moment that exceeds the Pass by spending twice the money on separates?

I am going directly from my Antelope Audio Platinum dac into a Wavac EC300b. Good attenuators on the dac obviate the need for a pre. It’s important to understand that a dac’s output only needs attenuation under most scenarios, i.e. the circuitry of a pre is only going to alter but not improve the dac’s output. The Antelope has good analogue inputs, too. My next stop will be something akin to the Audion Class Ds; the Wavac though is a formidable benchmark.

Voodoo,

I get it, although you have an excellent system you are restless right now.I used to have lots of boxes but then tried an integrated amplifier and never looked back. Now my system is only two boxes unless I include the Roon server.

 

 

 

@voodoochillin You clearly know what you're doing with that setup.

I have an XA 25 and it underpowers my Salk 87db speakers. I know that more power would make them sing, because I had an AVA SET 400 hooked up to them and they kicked more but (but were harsher).

In my humble opinion, I think the question is about power/current quantity, not the integrated vs. separates question, unless that is also separates-with-more-power. If you had a Pass integrated with much more power, I cannot imagine you'd not notice a lot of the change you'd get with separates with more power. My guess.
