The Lampizator is musical but of no real interest to me. It doesn't sound real.
Well if the L7 in stock tube form is somewhat dimensionally flat as is the stock B6, I would have to agree. But like any tube product, if one goes with stock tubes and tries no other, then they likely have already set the failing state of such a product.
We spend so much time tuning the rest of of our system with cables, isolation, room treatments, etc., but the tube products, with the potential of much improvement, are completely ignored….either out of laziness or the nonsense that we are told that the product was "voiced" for the installed tube set and thus this is the optimized implementation. Such voicing is often mediocre at best. I have been able to take EVERY tube product to a major level of performance increase with the swapping of one or more tubes.
As for what is musical is what I define as a system that makes me feel I am listening to the real mccoy. On some great recordings I have, on LP and Digital, the Lampizator B6 is mighty mighty close to the Clearaudio/Graham/Decca phono setup I'm currently using. The B6's tonality and dynamic contrasts are spot on and only lags behind the phono with some lost ambiance and depth.
I've been to enough audio shows to know maybe 1 in 10 rooms make it worth my while to stay more than 30 seconds. Much talk is the time to setup and let the system settle down in the "new" room. But I recently moved a system upstairs and had awesome results with the start of the first track…..room not treated or optimized at all. So I don't think it is a room issue as much as it is the assembly of products that work well as a system. Unless these have already been optimized ahead of time, it is futile to expect them to simply work well in any room whether familiar or an unfamiliar demo or mid-sized hotel room.
