Description

Using the great room which is centrally located between the floors and where, certainly in the late hours the family gathers, I felt this place is ideal spot where one enjoys music, as background or for more serious listening if the wife is not on the piano.

The custom made cabinet, designed for my AV needs in the mid 90s and placed directly against the wall, makes any change cumbersome so most tests are done in the HT system. The allocated space for audio gear is also limited, causing over crowding, certainly after the installments of the mono blocks.

Looking at modern and aesthetically pleasing integrated like the Devialet d-premier, one wonders if less is more.

The core data:

Room: located at mezzanine level, measuring 21' x 30' with a half sloping cathedral ceiling (from 7' up to 14') and an open staircase to the 1st and 2nd floor. Hard wood floor; two ASC bass traps are setup as well as heavy curtains in lieu of too visible room treatments.

Application: 2 channel only and likely to remain so.

Music genres: mainly Classical (mostly strings and vocals), modern Jazz, some classic rock

System/history:

After going through the bulk of full range speakers, some on Stereophile's top list within my budget, I concluded that I preferred time and phase aligned designs with soft dome tweeters and settled, for now, on a pair of Duntech Sovereign 2001s that complemented two other Dunlavy designed speakers. My favorites being the 2001s and the Black Knights, a dance of two.

Amplification was changed from ARC, Krell to Conrad Johnson. Their gold plating fronts "forced" me to stay in their family so I gradually moved up the chain, from tubes to solid state and now back to tubes. Now I am a happy camper with these LP140s.

The two above mentioned categories are pretty important and, IMHO, apart from room acoustics, the prime determinants as one does not know which sound one likes and only frequent visits to concerts, show rooms, classified sites and the occasional sanity checks ensure one is still on the right track and within a (somewhat) justifiable budget.

As for source, I intentionally and emotionally detached the analogue part as I am sure digital is closing the gap (there is still a gap) and it is so much easier to shift through the albums and tracks on your mobile device or whatnot without the addition of plops and cracks each time. Hence I have canned most of my CDs onto FLAC files and my collection of hirez digital is growing by the day.

As expected, electronics have their quantum leaps - and painfully experienced as I sold the then ground breaking high end receivers of the dot com era for cents on the dollar in the sobering up years of the dot bust - I remain on the outlook for the next DAC "du jour" and expect to have found a new love when I have more DSD files than the FLAC files on my server. The AMR DP-777 does a tremendous job, acting a pre and DAC. No DSD yet as hirez 24/192k files serve me very well.

Isolation is an interesting discipline where one needs to experiment a lot. Luckily, changing footers is easier for my back than swapping amps (except class D ones) or, heavens forbid, replacing heavy speakers. It is also a very mature industry segment with a finite number of players, unlike the next category.  The European Cherry cabinet is far from ideal so I need to address the resonance issue some day.

Finding suitable cables, let's start with interconnects and speaker cables, is an adventure that requires patience and tenacity. After reaching the first important relays in this marathon quest for sound, I ran a bit out of power but retained a good amount of brands for the short list and settled on Audience, NordOst and Purist Audio Design in alphabetical order. I have tried full looms of NordOst and Audience but have not detected any special magic. 
Adding High Fidelity Cables was very beneficial, not to my wallet though. Almost full loom HFC from digital, over IC to SC.

Power and power conditioning has really made me go bonkers as they do make significant difference so I have spent the last year searching for the nirvana/greener grass, first with a set budget until I lost my mind. It is not an easy undertaking: the diverse approach in type and composition of conductors, isolation, shielding, magnetic control, etc; the fact that PC are system dependent, and lastly that investment of a full loom of cables is not a trivial matter. I needed a firm nudge from my better half and a look in the mirror to halt the craziness, it did not. This contagious disease has not stopped and probably won't. My latest change of IC and SC to High Fidelity Cables has probably put a damper on future experiments in this area, for one the budget is pretty much gone and for the other these HFC are game changers that took my system up a big notch.

As for power conditioning, I will probably add a power regen unit but am now very happy with my Adept Response 12TS, upgraded from the non teflon version.

My short write up is incomplete but I could not pass the opportunity to post my system on a date like 11-12-13 so the "controlled" insanity will go on.

Thanks in advance for all your comments! Just don't forget to listen to the music.

Room Details

Dimensions: 30’ × 21’  X large
Ceiling: 14’


Components Toggle details

    • Cary Audio Design CD-306
    Liked this model so much I bought another for the HT system.
    • Conrad Johnson CT-5
    An excellent alternative to the ACT 2 Series II and as always, it just sounds right! Upgraded the 6H30DR, some improvement. As always, the after market fuse brought a big improvement. HiFi Supreme is very good but I do not expect it to last as new models come onto the market in a rapid pace.
    • Conrad Johnson LP140 mono blocks
    A big step up from the Premier 11A that I had. Replaced the stock Sovtek 6550s with first Gold Lion 6550 and then Tung Sol KT120, overall as good as the 6550s but certainly better and tighter bass. The upgrade of stock 6922 for the line stage to NOS Amperex with dutch heritage improved the sound, more so than the KT120.
    • Duntech Sovereign 2001
    Stock version
    • Logitech & linear power supply Touch
    with linear power supply (you dont need the more expensive Bolder variant, plenty of choice on Ebay) that clears up quite a bit and blackens the back ground. SW mod, thanks to Soundcheck from Germany.
    • Tara Labs ISM Onboard 0.8 digital
    between the Cary and AMR DP-777. Superb overall, lovely mids! The best I have heard in my system under 2k list price
    • NordOst Valhalla 1m and 2m power cord (2x)
    was long time my favorite in this all tube system, contested by newcomers like HiDiamond, still used as the first leg between wall socket and AR12T and from AR12T to DAC to get the high dynamics and high level of resolution
    • Symposium Svelte shelves
    19 x 24 under the source components and under the speakers
    • Black Diamond Racing Shelf, cones and pucks
    under each mono block. Will try Symposium Rollerblocks some day.
    • Audience AdeptResponse 12 TS
    very beneficial in improving the overall sound quality w/o only slight coloring. Traded up from the AR12 (non Teflon) so the extra investment is certainly worth while.
    • Furutech GTX-D
    Rhodium version and the best so far in my systems, more neutral than the gold version. Installed for both dedicated lines
    • HiFi Tuning Supreme fuses
    best bang for the buck, a must to have after market fuses. In combination with a dot of WA Quantum chips your system seems to make a quantum leap, a (very) small step for your wallet but big step for your music system!
    • Stillpoint Ultra SS (two sets of three)
    Pretty good improvement over the Symposium Rollerblock Jr. (in dual stacked mode), keeping the Symposium Sveltes shelves.
    • High Fidelity Cables CT1-U
    CT1-U digital
    • HiDiamond D8
    the D8 replaced a pair of HFC CT1E which have more resolution but does not offer the complex texture of the D8
    • HiDiamond P4 2m
    from Audience PC to the DAC
    • High Fidelity Cables CT1-U interconnect
    The best I have had/heard without taking out a second mortgage. Many will concur that adding HFC cables is addictive. I need a cure!
    • High Fidelity Cables CT1-U speaker cables
    Now I am requesting a second mortgage :-)
    • AMR DP-777
    • CH Acoustics X-20
    best power cord (so far) that has no downsides. Plenty of detail and speed, texture and imaging, great dynamics.
    • Star Sound Technologies Sistrum SP004
    under the mono blocks, improves the sound even more compared to Symposium Svelte shelves with Symposium footers.

Wow! Great system, always been a fan of CJ but never got higher up the chain than a premier 14 which I used for several years. Congratulations, bet it sounds incredible!

Thanks Mjcmt. The beauty of this hobby is that you can experience every increment of improvement and that they are multiple ways to it. I may try out different caps in the cross over of my Sovereigns this winter.

What a wonderful system and room. Systems like your make me want improve mine with better equipment.

System edited: Upgraded the Audience AdeptResponse 12 to the 12 TS, the Teflon added better resolution and separation between instruments. But I am not done yet in power conditioning, after upgrading the wall sockets, I will add a power regeneration unit in the next weeks and see if that give any improvements. Isolation: replaced the Symposium Rollerblocks with Stillpoint Ultra SS under all upstream equipment. Aurios now under the mono blocks.
