  1. Sticking with what I’ve got for now, thanks. Sunfire guy’s and my schedules won’t work out for a couple of weeks, so, on impulse, I bought a matched quad of Genalex Gold Lion KT88s to replace my Tung Sol 6550s. For a few reasons: 1) The GLs may be broad market tubes, but they get consistently good reviews. 2) The GL 12AX7s and 12AT7s I dropped in to replace the stock Electro Harmonix and Tung Sols made a substantial improvement in sound quality. 3) I’ve read that Jolida are known for shipping with cheap tubes to keep costs down, and my experience bears that out. Like I said, the Jolida’s sound is now on par with the output of the receiver by itself, just smoother and more “tubey.” Perhaps these new power tubes will take it to the next level in audio quality, and the original goal of a better two channel experience will be met. They arrive in two days. I’ll breakthem in for a couple of weeks and report back. Or maybe he Sunfire will blow my mind. Or maybe both!
  2. I’ve never heard if a Doge 10.
  3. I was calibrating for all 8 seating positions, and the rear positions were too close to the rear wall--that, and I was using a tripod. I switched to simply calibrating for the front three positions, and placing the mic on top of a stack of pillows so vibrations weren't conducted by a tripod. Night and day difference. We'll likely see about the Sunfire. If it isn't "it," then my search continues.
  4. That's a good question, George. I suppose emotionally, I'm looking to be delighted. Technically, I'm looking for detail across the spectrum: tight bass, smooth clear mids, and shimmering highs. I want a bit of punch, too. I want a wide, deep soundstage with distinct instrument placement (honestly, I've had that all along, just in slightly different flavors). I think I want what everyone wants--just in my room, with my ears. I'll know it when I hear it. I've replaced the 12AX7s (Tung Sols) and 12AT7s (Electro Harmonix) in the Jolida with Genalec Gold Lions, and the improvement was quite noticeable. Better soundstage, more clarity, more defined highs, slightly tighter bass (but not really tight enough). Now, when I switch between the Marantz and the Jolida, I don't prefer either sound. I love the definition of the Marantz. I love the smoothness of the Jolida. They're both great. But I didn't buy an outboard 2-channel amp to give me a "different" sound...I bought it to improve the sound I was getting out of my receiver for two-channel music. Refresher: turns out I was miscalibrating the room with Audyssey. Didn't discover this until after I'd sold the Parasound 2250 I'd replaced with the Jolida. I was quite happy with the Parasound, even with a miscalibrated receiver, and in hindsight, given what I know about calibrating in my particular room, I'll bet I'd have been over the moon with the Parasound had the receiver been calibrated properly. But that was not to be. What was to be, according to all the messages The Great Audio Whatever was throwing at me, was "TUBES!" at least, at this point in my journey. Yes, I could probably buy some KT88s or KT120s for the Jolida and dump some money on real NOS tubes for the preamp and power management circuits and find the sound I've been chasing (and maybe I will), but this is getting expensive...and based on what I paid for the Parasound, I'm beginning to think a) I'm an SS guy, and b) what I'm after can be had for at least what I've already shelled out, if not less. I have a local line on a 1997 Sunfire Load Invariant Stereo Amp for $500--that's 300wpc, and between the "Current Source" outputs and the "Voltage Source" outputs, I'm encouraged that I have a real shot at finding at least an acceptable result. So the journey continues. If I like the Sunfire, I'll sell the Jolida and be there. If I don't like the Sunfire, I'll likely sell the Jolida and start looking at used Parasound A21s, or maybe bu buy a Decware and wait four months while I listen to the Marantz solo. As problems go, these are all good ones to have, I reckon.
  5. Sounds like it may be worth the wait.
  6. Why does it have to be at the OPPOSITE CORNER OF THE COUNTRY?
  7. Well, keep in mind that the Marantz is a $2200 receiver, and it should sound good. Also, that the Jolida 3502P is not a high-end tube amp. Looking forward to the arrival of these new tubes to see what happens.
  8. After doing a bit of research and calling a few tube stores and talking to Jolida--I'm going to try replacing the preamp and power driver tubes (12AX7/12AT/7) with Genalex Gold Lion gold pins...now, they aren't Telefunkens, or NOS Mullards, or Tunsgrams, but they seem to be pretty close, and since I'm ordering them via Amazon, I have 30 days to return them. If these don't make a difference, it's time to sell the Jolida and keep hunting. Maybe that Decware IS the way to go.
  9. I used to have an AVR510. I’ve often thought of picking up another HK receiver. The 70s vintage receivers are ridiculously unaffordable at the moment.
  10. There is a pristine McCormack DNA-1 for sale on Ebay right now...
  11. I don’t dislike it. I was fully expecting to be blown away. Nope. But... I decided to use my Marantz SR7013 receiver for movies only, and the Jolida Fusion 3502P for music, fed by the pre-outs from the Marantz. In this capacity, the SR7013 is being used as a DAC and a preamp. I’ve installed an A/B switch—the front left and right speaker outputs of the Marantz int the A channel, the outputs of the Jolida into the B channel. The switch’s output feeds into my Cornwalls. This allows me to switch between the outputs instantaneously. And I have to say, the Marantz receiver, by itself, has a more detailed soundstage, with better definition between instruments, tighter bass, and slightly higher volume and more punch than the Jolida. The Jolida has more detailed upper frequencies— more “sparkle”—but it’s bass is looser and a bit boomy. It has a smooth, unpunchy quality. This had Jared at Jolida blaming the A/B switch. Not sure what adding a yard and a half of copper wire into the signal path is doing. He also suggested not toeing in my speakers. This led me to chase the theory that maybe I had the wrong tubes by reading everything I could about them for a week. I could spend hundreds on new tubes, then wait a month for them to break in to see if maybe yeah, it was the tubes...or maybe I could just start by replacing the preamp stage tubes, the 12AX7s...which led me to a phone call with Sean at Upscale Audio, who thought my problems could be solved with a pair of Tungsrams...for only $140...apiece. Hm. Not like you can return tubes if you don’t like them. But maybe I have gimpy tubes? DO tube amps sound better than good solid state amps? Or maybe I prefer SS to tubes? It’s frustrating. I remember listening to the Parasound 2250 (the one I just sold), thinking “This sounds amazing. I’m satisfied...but how can I be satisfied when it’s common knowledge that a good tube amp would sound even better?” Hence, the purchase of the Jolida. I’ve put about 300 hours on it, so it’s broken in...but it feels like my quest for great sound has taken a (small) step backward. I’m not sure what to do next.
  12. Picked up a Jolida Fusion 3502P in November, to augment the music output of my Marantz SR7013. Now that it’s broken in, the truth is, switching back and forth, I can’t hear that much of a difference. Maybe a more defined soundstage on the Marantz alone. I mean, it sounds great either way. But of course, I want it to sound “better.” 😁 So I had some questions: 1) Would it make sense to replace the 6550s that came with the amp with Genalex Gold Lion KT-77s? I’ve read WAY TOO MUCH about tubes, and these seem like the way to go. 2) The 3502P is switchable, allowing the use of either 6550 or EL34 output tubes. Which category do the KT-77s fall into? 3) would it make sense to upgrade the two 12AXA7 preamp tubes in the Jolida? These are currently Tung-Sols as well. I’m looking for a bit more detail and punch in the mids and bass, and a more defined soundstage. Overall, I’m seeking more clarity and presence. Thanks in advance.
  13. My thoughts after four months with the Jolida Fusion 3502P. It sounds good...slightly warmer than my Marantz receiver. But the soundstage isn't as well-defined. I spoke to Jolida, and they suggested I leave it on for a couple of weeks to really break the tubes in. So I did. It helped a bit, but the soundstage still isn't up to the Marantz. I've set up an A/B amp switch for movies and music. I use the receiver alone for movies, but it gets relegated to dac/preamp duty for music. I hate to say it, but honestly, I can't hear that much of a difference when I switch between the two on high-resolution music files. Here's the signal path right now: Cat6 from my router into my receiver, a Marantz SR7013. That's a AKM AK4458 DAC, controlled by Sound United's Heos, running Amazon Music HD and Ultra HD files, stereo line outs into the switch box, pre-outs into the Jolida. Switch Box outs to my Cornwalls. A sensible person would just sell the amp and be happy. That would make sense. So being me, now I'm thinking...new tubes? Currently the Jolida is running: 4x Tung-Sol 6550s 2x Electro-Harmonix 12AT7s 2x Tung-Sol 12AX7s Was thinking about replacing the 6550s with a quad of Gold Lion KT77s and the preamp tubes with Gold Lions as well. Or should I just sell the damned Jolida?
  14. Does anyone know the specs for the RB-5 II crossovers?
  15. Thanks for the PMs. Found a pair of RB-5IIs in Cherry locally yesterday, for $200.
  16. Happy New Year, y'all. Hey, I'm looking for a pair of RB-5s (or RB-35s), but I'm only willing to spend $200 max, including shipping. Cosmetics don't matter, as long as they function. So if you've got an old pair you just want to get rid of, please let me know, thanks.
  17. Yeah, this is the ad that started this thread. While I've gone with the Jolida...I just offered him $50 for it. I doubt he'll take me up on it, but if he does, it'll be only another $130 for tubes. Or someone could get a sweet deal on a Decware Zen Triode!
  18. It's too soon to tell for sure, but I MAY have reached the point where I'm actually satisfied with the sound of my system.
  19. You guys don't think I fried anything, do you?
  20. YES!!!!! OMG!!! I’d been tweaking the eq, trying to isolate the edge out of the high end. I did this and the soundstage opened up, every sound became distinct and the edge vanished. ok, I get it. I’ve got maybe, 30 hours on this thing...so it should be opening up around New Year. At this rate I think it’s safe to say the Parasound will be up for sale soon. THANK YOU, KEVIN!
  21. I just bought a Jolida 3502P to go with my '84 Cornwalls, and I'm pretty darned happy with it. Preamping with a Marantz SR7013 AVR. Replaced a Parasound 2250 v.2, and I have to say, I prefer the sound of the Jolida. More detailed sound, deeper soundstage. Smoother. Reveals crappy recordings, LOVES great recordings, and especially loves well-recorded acoustic instruments. Cornwall IVs should be amazing. Did you wind up getting them?
  22. Yikes! You're right! Nice catch, Kevin! Thank you.
  23. Ok, Day two was yesterday. Did a recalibration, repositioned the sub, and am happy to report that movies are quite enjoyable again. I have a weird room--vaulted ceilings--12' high on the speaker wall, 8' high on the back, listening wall. Ideally, I need to position my sub up front, so the waves are compressed and bounced the same way the fronts are...but there's no room. So I think I've found the best possible spot in the rear of the room. Still issues, but Audyssey crosses my Cornwalls over at 40 Hz, so the sub is on duty only for the low low frequencies. Seems to come in a bit abruptly. May need to figure out how to smooth the falloff. The Audyssey MultEQ app comes with this amazing curve editor feature. After it analyzes the room, it tweaks the receiver for a flat response, and generates a graph with a curve representing the response it's achieved (also gives you a before and after--really amazing stuff). You can plot points on the curve and edit it. So I punched up a bit of the upper midrange, and I think, aside from the abrupt subwoofer, we're good. This thing gets warm, and my rack is kind of enclosed on three sides, with little moving air. I'll be rebuilding the rack and putting the Jolida on top of it for cooling purposes (and prominent display) this weekend. Now for some time listening. Oh, and obligatory unboxing pics:
