  1. You are off to a great start. There are better speakers in the world than Klipschorns, but not many, and not by much! You really are starting pretty close to the top of the heap. I think your amp choice is great for getting started. You might be able to do better, but I wouldn't go rushing off spending a bunch of money just yet. My recommendation is get your new amp and crossovers hooked up and just enjoy for a while. You may later discover that you want to treat your room, or add a sub, or upgrade your amp etc., but take your time deciding. It takes listening for a while to really determine what you like and don't like about a system. Live with it for a few weeks or months, play a bunch of different types of music and just get used to having a really good hi-fi setup. You'll probably re-discover a lot of old favorites and truly hear them for the first time. Enjoy!
  2. Beautiful home and system. Good luck with your repair!
  3. I have never been one to chase imaging. Sound stage... maybe, but not imaging. It always seemed like a hi-fi salesman's gimmick more than anything that represented reality. I have been to lots of live concerts; the only time I have ever noticed any kind of imaging is small-scale, non-amplified settings. I think hi-fi systems and products that are designed around imaging largely miss the mark about what makes hi-fi, and music, great. Smooth, wide frequency response, flat phase, even dispersion and dynamic range are what it is all about. Thank you PWK! However, I have found that as a system gets better, so does its ability to image. Though I have never chased imaging per se, my system images quite well. It turns out that a well-treated room, flat phase, smooth frequency response and even dispersion actually make for great imaging as well. So while I don't find it a worthwhile characteristic to pursue, it can actually be a good indicator of system performance, all else being equal.
  4. Those look great! Well done. What veneer did you end up choosing? Is that Walnut?
  5. Was yours an HD? I have no noise floor issues at all with mine.
  6. MiniDSP 4x10HD user here. Unfortunately, there is no automated solution that provides what you are looking for. The process of setting up an active digital crossover and EQ is an iterative on that involves measuring, adjusting and repeating the process until it sounds and measures right. It really isn't too hard once you get it all figured out, and I find the flexibility on tailoring my system to sound the way I want to be amazing. I can't imagine going back to analog electronics again. As far as sound quality of the MiniDSP units goes, I have never heard a non-HD model before, so I can't comment on those. I have also never used any of the Xilica products. However, I can say unequivocally that my sound quality improved DRASTICALLY when I ditched the analog crossovers and switched to the MiniDSP setup. If the MiniDSP is messing with my sound quality, I sure can't tell. And it is certainly degrading it FAR less than an analogue crossover would. I think the doubts about sound quality with any modern-generation DSP based crossover are likely unfounded. They are at least as good as any other piece of equipment in a typical system.
  7. World War Z right now, haha. I just finished reading two pretty heavy books, so I went for something a bit lighter this time. Just finished Midnight at Chernobyl and With the Old Breed. If you have never read With the Old Breed, you should. It gave me an entirely different perspective on WWII and also on life in general. It has made me extremely grateful for the life I have.
  8. I run a THT with my setup. You are right, the output and depth is very impressive. I have considered building a second one, but they are huge. I could fit one, but it would take up space that I'm not sure I want to give up. Maybe when the kids are grown....
  9. Rebuilt my Marantz last year. Before, during and after photos:
  10. I bet this room/system sounds fantastic! Congratulations on reaching this point. I look forward to seeing more!
  11. So, not exactly an economical alternative to a 402, haha.
  12. Is this thing available for sale anywhere? I can't seem to find it.
  13. Looks great! One of these days I'll get around to veneering my old H1s.
  14. Fascinating insight into the state of the art 60 years ago! Thanks for posting. I love the vintage stuff, and collect it a bit. However, I'm with you Claude. The modern stuff is orders of magnitude better than stuff from 1963. In the end, I'd love to have a Paragon in my living room. They are so pretty, my wife might even allow it! I'm certainly not going to get rid of the modern stuff to get one though.
  15. Check into infinite baffle subs. They are usually build in-wall, in-floor, or in-ceiling. They require a very specific placement that may not be possible in your room (it wasn't in mine). However, if you can make it work, they offer some of the cleanest, deepest bass available.
  16. I definitely appreciate the mathematical analysis from Langston and Backfire. I would agree that horn-loading your woofers adds an order of magnitude more damping force than any amplifier can. I would also agree that a lot of the difference in what people hear in tube amp bass is a result of the interaction between high output impedance and uneven speaker impedance. For all of these reasons, and many others, I have found active crossovers to be an excellent solution. Use the big SS amps on your woofers, and then use whatever else you prefer on the mids/highs (tubes, class A SS, etc.). Seems to offer the best of all worlds.
  17. Material shortages and extended lead times seem to be affecting all industries at the moment. I deal with it every day in my business (construction materials). Most of my vendors are telling me that it will continue through the end of the year AT LEAST. I also recently ordered some drivers from Parts Express. I got 6 out of the 8 drivers I ordered. I was told the rest would be shipping by the end of the month. I guess we'll see....
  18. I built a Latino ST-70 a couple of years back. Like you, I had a great experience building it and had excellent support from Bob. I can't recommend him enough when it comes to buying a tube amp kit as a first time builder. I also had an issue with rectifier tubes. I had one blow and take out the output tubes with it. Swapped in all new tubes and it happened again! I changed brands and finally found a set that works. Have been using this set for over a year with no issues. I don't remember which brands I tried at the moment. However, trial and error seems to have solved the issue. Wish I could be of more assistance. I know trial and error is not cheap when it involves tubes.
  19. Don't have too much to offer here other than that I love the sound of my Marantz 2230. It is not paired with any of my Klipsch speakers; I have it hooked up to a really cheap pair of Yamaha 3-way bookshelf speakers in a second system. This combo sounds WAY better than the cost of components would lead you to believe. Easily 90% of the sound quality of my big Klipsch-based system at 1/10th of the cost. I am not sure what the going price is for these old Marantz units, but they definitely have a very smooth and nice sound. I paid $10 at Goodwill for mine, and then spent $90 on a rebuild kit to replace the caps and lights. It is like a brand new unit. For the ~$100 I have invested, I don't see how you could do better.
  20. I have no experience with the BMS, but I used a pair of B&C DE750TNs on some ZXPC horns for the past couple of years in a two-way configuration. Just recently switched to some Eminence drivers for better high end. The B&C drivers worked great from 400hz up. They are very robust and had no problem with the 400hz crossover point. Sounded great in the mids, but the Ti diaphragm is not the cleanest up high. If you are using them in a 3-way configuration, the highs would not be an issue.
  21. As jjptkd said, this is absolutely possible by using adapters. Though it was not a tractrix horn, I have swapped out the k400 horn, while continuing to use the K-55v. See this thread: Initial impressions were good. However, the problem with this approach, which you will see in the thread, is that the K-400 (and k-500, k-700 presumably) was very carefully designed to work with the k-55v. PWK used the "pattern flip" effect that results from the loss of directivity that the K-400 experiences to complement the natural frequency response of the k-55v. They are engineered so that the directivity loss occurs right around the point that the frequency response of the k-55v starts to drop. This keeps the on-axis frequency response relatively flat. If you put the K-55v on another horn that does not have this property, it will require EQ.
