Lalitk - Great Choice !!! Those are sweet and you are going to love it.

Congrats!!!!

I love those! I am enjoying playing around with my Aries and improving it but I have my eye on either an Aurender or Antipodes and I am sure one of those will be on my short chase down and tackle list soon enough.

Awesome choice. I know for sure their sound is excellent and one of the best but they are hands down the best looking, best build and slickest units out there. Very cool...

Wisnon makes a good point about the Lampi's in that used price range for their DSD but I really like the DAC you were leaning toward already the Modwright Elyse DAC.

I like the Modwright stuff and I think it will be a fantastic match to your great transport choice!!!

I love the build concept of the Elyse and his approach to his power supply design. A power supply that uses the natural sounding tube rectification but ties it up tight with dual-discrete solid state voltage regulation. That is a nice approach to combo both strengths into one power fine supply. I like it.

Then he adds in the sweet Lundahl tranny coupled inputs which will tether up your transport the right way and then he doubles down with the Lundahl tranny coupled outputs so no preamp will be needed with his pure Class A / zero feedback implementation of the 6922 in the output stage. This tube which let you tailor your sound better than any other tube I know IMO. Love the 6922 who needs the super tube anyhow. Now you just need to get yourself a pair of Upscale / Platinum / Cryoed / Pitched Waist Amperex PQ's and a Mullard Blackburn Factory built circa mid 60's GZ34 rectifier Tube (get the Hammond organ labeled ones and save some scratch for exact same tube) and you are good to go. You will be first rate all the way!!! Congrats again and great choices ...

Fsmithjack,

I am really looking forward to Elyse DAC. I just installed a pair of KWA150 SE, they are powering up my 800D's in bridged mono configuration. Hands down, one of the best amps I have heard in a while. They outclassed my Classe M600, actually smoked them!

I thought about Auralic Aries a lot but the build and SQ quality out weighs the $1100 price difference. The way used market is, who wants to risk reselling Aries at $1K range in couple of months.

As far as the tube mods go, Dan already recommended following tube replacements -

(2) Electro Harmonix 6922 TUBES - Stock Tubes
- Recommended Upgrade (that they use at the trade shows) Tungsram PCC88 / 7DJ8 - http://www.upscaleaudio.com/tungsram-pcc88-7dj8/
(1) Sovtek 5AR4 - Stock Tube
- Recommended Upgrade, NOS 1970 Philips 5R4GYS - http://www.upscaleaudio.com/philips-5r4gys

I plan to listen the DAC with stock tubes first and then swap them out with recommended tubes. The DAC being shipped with both tubes.

Modwright makes very good stuff, but the DHT tubes are incomparable. I have played around with ECC88s, ECC40, ECC81/82/83 of all kinds of exotic old brands from my local tube guy and they are great, but the, 345s, 45 triodes (mesh plate), the 101ds, 300bs, 6A3s, etc combined with the big bottle rectifiers do it for me.

I have (as rectis) metal base Philips GZ34, Mullard GZ37, vintage 5u4g, 5AR, new production 274b, military spec double mica 5r4gy, etc, all from the 1940s to 1960s. When combined with the big bottle DHTs are a quantum leap over the small signal tubes and especially for DSD.

I have NOT tried the uber expensive 300bs like from WE vintage, Takasuli, Elrog, etc nor the EML anniversary 45 globe (unobtanium). people say these are worth the high pricetag.

Wisnon - I totally agree DHT Tubes are the very best of the best. You get nothing but agreement here but those would prob match my system a lot better than Lalitk's. I love DHT - I have switched my "entire" system around and provided an entire and radical system refit so I can feature the DHT tubes. I live for my 2A3 custom amp so I am all in on that program. His system is a lot different with those great beasts of speakers.

Lalitk

Regardless what any one else even the designer tells you I promise you and you can write this down (lol...that's what I am doing) and put me on record saying if you buy the tubes I recommended and then you buy the ones he recommended you will listen and prefer my recommendation 10 to 1 min more like 100 to 1 but that's just my opinion but tubes are tubes.

The better tubes the better they sound and the combo I recommended is the best there is IMO. I know he will quote synergy but that's crap.

The pinched waist PQ Amperex will obliterate that Tungsram in any system any time any place IMO. The main reason anyone uses the Tungsram tubes is because it is super quiet and super clean. I own a few of them. They are dry, sterile, thin yet uber detailed and super duper clean and quite fast while ultra quiet but trust my word and anyone else will agree if you are getting the best platinum matched from upscale then the Tungsram will be like a NAD/Rotel/Adcom tube and the Amperex PQ is a Vitus/Bumester/Gryphon.

There is nothing a Philips 5R4GYS can do against a Mullard GZ34 IMO. But buy his recommended tubes and enjoy and then when some time goes by go get the ones I listed and when you plug them in and listen you will be wholly smokes.

Better tubes go a long - long - long way! Truly great tubes (i like the blue label 6201 Valvo's also just not as warm) are def worth the added expense IMO for sure!

Awesome stuff though. I am surprised that KWA150 SE bettered the those killer M600. I assume the M600 is warmer. Maybe the more warmth you like less. Either way the tubes I listed are better at everything in every regard but they will warmer than the Tungs so you could go with the blue label 6201 Valvo over white label PQ Amperex pinched waist 6922 either will be incredible and much better than the Tungs. Good luck !!!

Fsmithjack,

Thank you again for making some great and thought provoking recommendations. I never dared myself into experimenting with tube mods. I bought Raysonic CD-128 with class A triode vacuum tube (4x6922 triodes tubes - Russian) few years back. And left it as is cause it sounded pretty good out of the box. As of last year, I added components that are bit more revealing. I have been trying to build a system that is musical, tonally accurate and dynamic.

I added M600's earlier this year to my 803s, nice upgrade from CA-2200. The CA-2200 was more than adequate for 803s; M600 was purchased in anticipation of next big thing. Adding 800D2's was a huge step and quantum leap. To my surprise, despite of its good virtues M600 tapped out in the bottom end with 800D's.

I looked at Krell, Pass Labs, Simaudio and Ayre before settling down with Modwrights. Like M600, KWA150 SE treble is open, detailed and natural. The sound is consistent across a vast array of frequencies. What separated KWA from M600 is its deep bass, that is just tuneful, agile and full in level.

Like you suggested, I am going to spend some time with Elyse and venture into the exciting world tube mods in near future.

Let the fun begin!
