I find John Martyn is already mixed with heavy bass and heavy rich tube sound - very resonant and pleasant in small doses at lower volumes - personally I would not try to overdo the harmonics but I'd be interested in the results of your experiment.
And although I think my system is as good as it can get I am curious to hear it with an all tube amp. I've never heard it with an all tube amp and would love to. I'm thinking either Quicksilver, Rogue, or CJ. Perhaps some day ...
I gave John Martyn some heavy rotation last night too - along with a nice Whisky to toast him! Delicious sounding. Life is great! I am deeply thankful for so many great musicians and teh recording industry as a whole for bringing such joy to everyone!
Shadorne - Thanks. John Martyn sounded spooky good last night - Solid Air and Bless the Weather. Good stuff. Have not spun Stones since I got it all dialed in to my liking. Thanks for the idea though! Think I'll start with "Now", and then "Exile". Followed by "Jamming with Edward" of course (bwah, hah, hah, hah ... I don't think Bob did that one, eh?). ;^}
I may have finally reached my goal: Andras on the "cheap", albeit with dismembered subs and lower cross-over settings. But hey! Sounds good to me!
Yeah. I'll bet it sounds good. The Rolling Stones shou1d sound close the way Bob Ludwig mastered them (on his Egglestons). Nice choice of gear. How does John Martyn sound with both subs?
Lapierre, thank you. One sub is placed right front, to the right of the right main, and the other is kitty-corner, diagonally across on left behind seating position. Both are set to equal volumes at listening position and equal cross-over, around 65Hz. For my system/room this proved best integration (flattest response) with 85Hz high-pass in-line passive filters on amp input lines. I had one sub at first, but it just did not seem to energize the room enough. By adding the second I was able to flatten a few peaks and nulls in response curve, and also properly energize the room when called upon. My goal for this system all along has been: musical, clear, extended on both ends, and non-fatiguing. I have finally achieved this objective with latest upgrade to tubes in my amp from JJs to Mullards. I am now completely satisfied and thrilled about my system. I am done shopping for gear and will now solely concentrate on pursuing more music.
Second sub now integrated into system. Ended up using the 85Hz filters on my mains and connecting the two subs as stereo. Subs' phases: locked in. Subs' volume levels: equal and locked in. Low-pass settings on the two subs set to approx. 70Hz. All I have left to do is tweak the low-pass settings on the subs for optimal integration. But already the addition of a second for stereo subs sounds fantastic. I may have finally reached my goal: Andras on the "cheap", albeit with dismembered subs and lower cross-over settings. But hey! Sounds good to me!
System edited: Added a second subwoofer! This one also an ACI Titan XL but newer model in Satin Black. (By the way, if anyone wishes to trade out their old style Titan XL in Rose Walnut for my new, fully warranted B-Stock Satin Black just let me know as wife prefers previous model.) Currently breaking in the new one alone. Next step will be to position and connect second sub to experiment and determine if subs will be either two summed (matched) signals to smooth out peaks/valleys in LF response curve, or stereo (Left channel to one and Right to the other). They will be positioned sort of randomly kitty-corner from one another, though not in the corners as I don't have any. Have two sets of ACI passive in-line filters with which to try on the mains as well: 65Hz and 85Hz. So several iterations are required to determine best results. Feel free to comment on which way you think I should go with two subs: summed or stereo, and which filters for which set-up.
System edited: Added pair of ACI 65Hz Passive High-Pass in-line (RCA) filters to relieve mains of some lowest freq. duty. By doing so also cleaned up sound, improved imaging, and widened sounstage. A great cheap tweak!
System edited: Finally addressing my room a bit. Added three GIK Acoustic 244 Panels to the wall behind my head to kill the bass null off the back wall and help with the boominess of sitting near (3') a boundary
For anyone else with the Fontaines and Titan combo, FWIW, I set the cross-over to the lowest possible setting. This gave me the best integration - i.e., you don't realize that there is a sub in the system. And for anyone fretting over getting a sub or not for fear of it messing up your current imaging and cleanliness of detail, fret no mo. It can be done, at least with an ACI sub. Measured (and corrected) response at my listening position for the lower region (without any additional room treatments): 20Hz -7.8dB 25Hz -5.6dB 31.5Hz +1.9dB 40Hz +2dB 50Hz -2.2dB 63Hz +.8dB 80Hz +1.5dB Between 63 and 80Hz the sub no longer has any effect on the response.
Thank you for the (as always) kind words. Every now and then I wake up in a cold sweat (ow! I feeeeel good, knew that I would now), worried that I need to replace my mains and sub for full-rangers. But then I just pop in Mark Murphy, Miles, or Roland Kirk, and I forget all about replacing gear. Ahhh ... the sweet sound of plastic drivers ... (tee-hee)
"This system needs to be moved to "DONE FOR NOW", as I am completely satisfied with its sound. But I don't know how to easily move it, so I guess it will sit here." -Rockadanny
Rockadanny: Dude, you used the "s" word! Not too many audiophiles can do that! Very nice to hear someone saying "satisfied." Thanks for the good news. -Bill

System edited: The final two pieces are now in place: mod'ed player (Consonance Ref. 2.2, mod'ed by Stephen at Quest For Sound) and new preamp (Line 2A SE/ PS 2 by Dr. Llyod Peppard - Mapletree Audio). My system is immensely satisfying - highly musical and effortlessly enjoyable.
System edited: In my quest for more (grunt/snort) power to make my 87 dB Fontaines "sing", I've purchased a Van Alstine Fet Valve Ultra 550 - and sing they now do. I've relegated my a120 integrated to preamp only use. It is a shame to semi-retire the a120 into partial use so I plan on selling it and getting a dedicated preamp. I'm thinking along the lines of either a Van Alstine Transcendence T8 (all tube), Quicksilver Audio Linestage, or perhaps a Transcendent Sound Grounded Grid (self-tweaked).
Thanks Danny,Bill ,im hoping the force will be with me in a few weeks!I love my Caravelles and think the Force will add the finishing touch !Danny ,yours and a few others experience with ACI has given me confidence that im making the right choice,if money was not an issue i may have gone with REL,,i will try the connection from my CJ MF2500A amp first as i have a 10ft. pr. of Sonoran Platau speaker cables collecting dust but no long ICs.Thanks,Ray
