Kinki studio EX-M1, EX-M1+ differences... vs Denafrips Hestia/ Hyperion combo?


I've been reading up on some Integrated Amps and Pre-Amp/Amp combos lately but have some questions.

The following is an excerpt from SoundStageHifi:
The original EX-M1 was introduced in 2017. The newly updated EX-M1 — without the “+” — costs $2398 and includes, among other things, changes in the power supply, capacitance, and the volume control, the latter now using a MUSES72320 controller instead of the previous relay-based control. The EX-M1+ is essentially identical to the upgraded EX-M1, but adds a preamp-stage output and a home-theater bypass to entirely bypass the preamp stage.

That last sentence has me a little confused. 
"The EX-M1+ is essentially identical to the upgraded EX-M1" - What is the "upgraded" EX-M1?  Does this mean that the latest version of the EX-M1 has all the updates that they just covered preceding this statement?

The 2nd half of the statement says " but adds a preamp-stage output and a home-theater bypass to entirely bypass the preamp stage." - You'll have to excuse my ignorance.  Does this mean that I can add a pre-amp in the future and use the EX-M1+ as a Power Amp?  Also, does this mean that I cannot add a pre-amp to the EX-M1 (non-plus)?

At this time, I don't have hard to drive speakers, and I don't foresee having something like that anytime soon, so I was also considering the Denafrips Hestia/Hyperion combo.  I haven't seen any reviews comparing these 2 company's offerings... any feedback is appreciated.

Can you just give me his cell phone number, I’m sure he won’t mind. hahahaha Thanks for the heads up. I’m already leaning toward the M1+ now, but would still like to get as much feedback as I can before I spend more money.
regismc,

I'll be mating this amp with the Klipsch RP-600M, but I see an upgrade in the near future, possibly the Heresy IVs.  I ordered a Decware tube amp, but it's still like a half a year out, if not more.  I've been hesitant on the BHK 250, not only because it ups the price so much, but also because I'll have a tube amp coming sooner or later, I was planning on adding a full solid state amp to the collection.

jond,

After you said it is pretty clear to you, I re-read the sentence, slower this time and it is pretty damn clear.  haha 

Thanks!

regismc,

Thank you for your impressions.  I'm getting a similar impression, albeit without any real-life experience with either system.  I'm told youtube's audio is heavily compressed so I take all the videos I watch with a grain of salt, reviewers included.    

Damn, I am getting into this price territory now, where if I spend a little more, I can get the Pass Labs INT25 or the PS Audio BHK 250 power amp (I have the opportunity to buy it for 30% off right now).  This is seriously an addiction.

Jackd,

Thank you for your impressions with the kinki and bhk!  I have the opportunity to buy a BHK 250 for about 5k.  I was actually comparing that price with the Denafrips stack, which I'm also considering. 

I've love to hear more of your impressions comparing those 2.  I've been reading that my DirectStream DAC benefits greatly from a pre-amp, so initially I wanted to buy a power amp and live with the volume control on my DAC until I get the motivation to spend even more money on the BHK pre amp.

This is real dilemma. Is the BHK that much better? Is it better?

Regards,

@regismc and @sns 

Thanks for the feedback.  These Kilpsch are currently my speakers but I will probably venture out into other makes and models in the future.  As you mentioned, the Decware will probably drive these pretty well.  I've watched reviews about some of the models you mentioned and I was considering them as well.  I don't mind spending a little more now if I can future proof, if that is even possible.  With all the "synergy" talk with components, I know it will be difficult.  I guess part of the fun is upgrading and trying new things.  At one point, I thought about building those Pass Labs Amp Camp Amps to get a taste of that sound before I spend too much.

@mboldda1 I've never heard of those Norma amps before.  I'm going to have to check those out as well.
@mboldda1  - Thank you.  It was nice to read about something else besides what all the reviewers are taking turns reviewing.

I've decided to go another direction due to a sale that brought an item down into my price range.  I wish I would have seen the sale sooner, but oh well, I learned a lot during that time.

Thanks everyone!

I didn't know you cared!  hahaha

I ended up with a First Watt F8 (Picked up 30mins from me =) and I was able to get a 30% discount on a new PS Audio BHK Preamplifier.  I found out about the PS Audio sale after I bought the First Watt F8.  I could have ended up with the PS Audio BHK 250 + BHK Pre, for about $1k more.  The BHK Pre is getting built right now, so we'll see how it sounds.  So far, the First Watt F8 is getting better and better as it burns/breaks in... it is also on the bottom shelf, but near my thermostat and my place is freezing in every room when it's on. This amp runs HOT! lol
@jackd 
Thank you for the info. What does "lift the ground up" mean? I've read about all the quirks of this preamp, but it seemed to be a trade off people were willing to deal with because it improved their sound.

I was looking into the Decware zbit to increase the voltage to my F8 because right now with the DAC controlling the volume, I can max it out and it's loud, but nothing too crazy.  I'm just not used to having my volume at 75 to 90% all the time.

I don't plan on tube rolling any time soon, so I'll have to cross that bridge when the time comes.

Like you mentioned, since the F8 is SE, I've wondered if it's worth connecting everything else with XLR.  

What amp have you matched the BHK Pre with?  Do you have an experience with mating it to the BHK 250?
@jackd

I take it "lifting the ground" removes noise?  Worst case I can just return the BHK Pre, or sell the F8 and buy the BHK 250, I guess.... hopefully I don't run into too many quirks.

Thanks for this info, I know what to expect.


So after I started this post I went bonkers.  I now have the First Watt F8, a Yamaha B-2 (Vfet), built the Nelson Pass Amp Camp Amp and have a BHK Pre on order.  I have to say the F8 and the B-2 are amazing amps.  Comparing the characteristics of these amps vs the $100 Class D SMSL SA 300 that I also have, I learned that I really enjoy the forward midrange presentation... or vocals that are more forward, if that's what forward midrange presentation means.  I'm still very curious about the kinki and denafrips offerings but need to calm down on the spending.
@jackd 

Thanks for that.  Why do you think this is the case?  I have thought about buying an XLR to RCA that boosts the voltage a little bit so I can use the balanced interconnects.  If I build another Nelson Amp Camp Amp, I could have an amp with balanced outputs in dual mono configuration, but the F8 and this Yamaha is noticeably better, at least to my ears.  I hope they send me new tubes, PS Audio is building my BHK pre right now, so at least the unit is new production.  It's been like 3 weeks already, hopefully they will finish building it and send it out to me soon.
@jackd

Thank you.  I have 4 amps, all with SE inputs so if that volume control is unbearable, I guess I'll have to think about returning it.  I do use the volume control often since I use this system from multiple sources.  I really hope that it works out for me though.  I've been hearing such good things about this BHK Pre.
