Steve has already commented on our Italian hosts so I’d like to weigh in as well. To begin, what continues to strike me impressively is the genuine camaraderie and affection that audiophiles have for each other. Gianluigi and Marco continued to reinforce that impression. To be honest, it was embarrassing for us to continually decline their generosity during our limited time with them. ‘Let’s take you out to lunch”. No sorry, we can’t. “Let us take you out for drinks”. Uh, no, sorry. “Let’s stop for the best gelato you ever had”. Yer killin’ me Gianluigi, but, uh, no thanks. “Let’s go to your hotel and pick up your wives and we’ll drive to lake Orta which you really must see”. So sorry Gianluigi, but we simply do not have enough time. “I know you can’t take time for drinks so we brought the drinks to you”. OMG, to say these guys were the epitome of hospitality is an understatement. Audiophiles. Gotta love ‘em.
As Steve mentioned, our first stop was Gian’s. From the moment I walked into his listening room, I knew it would be a special experience. And it wasn’t the gear or the room that told me so. It was his music collection. I could have died and gone to heaven right there. It wasn’t the numbers that was impressive even though they certainly were (just a few thousand+ CD, LPs and assorted tapes), but the content. Gian is a jazz freak, as am I, and his collection left me drooling. IF there was a cut-out in the listening chair for a toilet, and somebody could hook me up to an IV for nutrition, I might never come out of that lair. This was the finest collection of jazz I have ever seen in one location. Exquisite taste on steroids, to say the least.
Although his speakers are hardly a household name in the US (or anywhere for that matter), they demonstrated some highly distinguished properties that were very impressive. As Gian rightly stated his system is fast. Very fast. Although this property is of course due in part to excellent electronics (all CH precision electronics), I couldn’t help but think of one thing in particular that may have a large contribution to the overall sound, which was the highly unusual crossover in the speakers. Most speaker crossovers (whether 1st, 2nd, 3rd, or 4th order) utilize electrolytic capacitors in their design. And the values needed are simply too large to use the more desirable film capacitors (i.e., polypropylene). When I designed crossovers in my younger days, I always used the best electrolytics available (Black Gate), but always wondered if it would be possible to use polyprops. I’m sure many others thought about this as well. The general answer is that constructing a crossover with polyprops would be essentially unrealistic as the number of caps need to approximate the values of a large electrolytic, would just not be feasible. Even if one used a large parallel/series array, such an array would not only be enormous and likely never fit comfortably in any speaker cabinet, but prohibitively expensive. In short, you’d have to be nuts to even try it. Well, that’s apparently what Gorgio Montagna did in designing his Spark 303 loudspeaker. See post #235 for a pic of the crossovers that used all polypropylene capacitors. By my count, the number of caps used in the bass/midrange crossover was at least 420!! (I could not see behind the group that was visible so I’m not sure of the final number. And also note the crossover units are cleverly mounted on elastomer mounts to minimize vibration.
The big advantage of using polypropylene capacitors in such a series/parallel array is that such an array will have a much lower ESR (equivalent series resistance) than any electrolytic. Simply put, decreased resistance (or reactance which is frequency dependent) translates to speed. And my guess is this is the great secret of the Montagna sound. (Did I mention “fast”!!). I’ve never seen this implemented before with any other speaker, and can’t help but wonder what improvements might be enjoyed in other speakers if such a crossover design were used?
After some enjoyable listening, we then went to Marco’s and my first thought after walking up the spiral staircase 2 floors to get to his listening room, was how the hell he got his Wilson X-1s there? It turns out he brought them in via a crane through a window! Talk about dedication.
Marco’s system used the same CH front end as Gian’s including the wonderful Bergmann Sindre turntable (everyone knows I’m a straight arm proponent ) with a key difference being Marco’s use of the Lyra Atlas (which I have never heard before and was impressed) vs the Air Tight Opus in Gian’s system. A key difference was that Marco used a lovely Vifa tube amp to drive his Wilson’s and in addition, he had some effective sidewall room treatment to prevent bounce and comb filter effects. These synergized to provide a highly musical sound. Then again, my bias has long been that the combination of SS and tube electronics is often very enjoyable, and Marco’s system demonstrates this very well. It was also a real treat to hear the Bergmann Sindre in 2 systems with identical front end electronics (CH Precision).
Then it was back to Gian’s for some tape playback. Sure, why not wait until I recover drooling from the earlier LP demos before you knock it out of the park with tape? Gian concluded the session by putting on a tape of the spectacular RCA’s Living Stereo “Witches Brew”. I had to be peeled off the floor when it was over.
I’ll conclude by saying the same thoughts I mentioned Initially. Audiophiles. The friendships I have made (and I suspect we have all made) that is what is special and lasting. Sure, we may disagree about this and that (hell, that’s why we get up in the morning!) but in the end, it’s the love of music and how we choose to reproduce it at home that are the ties that bind. I never fail to learn something all the time from each interaction. But more it’s the friendships that count. Gian and Marco couldn’t do enough for us and I still feel bad about declining their multiple invitations. With better planning, I’ll not make that mistake again on my next visit! And of course, I’d be delighted to host their visit if they should find themselves on this side of the pond. Fair warning however- I can’t provide the Italian food they are used to, but I can hold my own when it comes to not disappointing them with wines to drink!
