Puritan 136 vs 156 for simple system

Thanks for the great input so far. I have upgradded my cables and most everything in my system minus putting in a dedicated network switch and already have plans for that. I might just try and find a used 136 as its more inline with the cost of my system. Any input on a good semi budget friendly power distribution/filtering block would be much appreciated. Around $500- $1000

Also the reason why I am looking into changing out my power setup is I am currently running an older Panamax 5500 AC regen unit and I am thinking that is probably hurting my setup more than helping it. 

Thinking maybe I should just get a solid power distribution block for a lot less money. Wisdom Cable Technology seems to make a really nice one.

I have to disagree with @audphile1 about upgrading your DAC unless you are prepared to spend $4500 on a used Holo May KTE it is unlikely you will actually hear any significant improvement over the R26 with a lesser DAC.  If you want to upgrade the digital side buying an LHY OCK-2 external clock is absolutely going to improve the R26 just make sure you use at least an LMR400UF BNC cable with it.  But in general the R26 is an excellent DAC for its price and the A6 isn't bad either and yes I have owned both.  But I do agree with him that it is unlikely you will get any significant benefit with a power conditioner given the level of the rest of your system.  Do you live in an urban apartment where you have reason to believe the power is dirty?

I don't think you said what your speakers were?  Better speakers are usually the most bang for the buck in any system.  Then room treatments, then the amplifier.  

@pinwa there are DACs under $3500 that would provide an upgrade over R26. Chord Hugo TT2, Bricasti M3, PS Audio DirectStream, possibly the new and highly praised LAiV Harmony…just to name a few. 

With all due respect…upgrading network components in that system and adding a high end network switch is like installing an ejection seat on a helicopter. 

Here’s a power strip recommendation for OP…
