Ένα...επεισοδιακό review από το Stereophile για τα μηχανάκια της Boulder.

O πρώτος reviewer, ο Fred Kaplan, τα θάβει (ειδικά τον τελικό). Φωνάζει και τον Wes Phillips στο χώρο του και διαπιστώνει κι αυτός προβλήματα στην ηχητική τους απόδοση.
Ο Atkinson εν τω μεταξύ τα έχει μετρήσει και τα μηχανάκια τα πήγαν πολύ καλά... Τα ακούει, που λέτε, ο John στο δικό του σύστημα και δεν διαπιστώνει κάποιο πρόβλημα με την απόδοσή τους. Αντιθέτως παίζουν πολύ καλά (ως όφειλαν με βάση το price tag). Τα στέλνει και στον Wes, ο οποίος τα ακούει στο σύστημά του αυτή τη φορά, και αναφέρει πως παίζουν καταπληκτικά.
Μήπως κάτι δεν πήγαινε καλά με το σύστημα του Fred; Πάντως ο τελευταίος "τα ακούει" μια χαρά στο "Manufacturer's Comment". :happy_9:

Για του λόγου το αληθές...


"Conclusion
The Boulders are handsome pieces of gear, inside and out. The 810 preamp sounded very neutral, with only a slight softening in the bass and an even slighter rolloff in the upper octaves. The 860 power amp was superb at capturing harmonic overtones and dynamic contrasts, at placing images precisely on a soundstage, and at illuminating that soundstage—at letting the listener peer all the way into the stage, from left to right, from front to back, from floor to ceiling. However, the glare and darkness in the upper midrange, as well as the fuzziness in the deep bass, were, in my mind, out of character for an $8500 amplifier. Overall, I was left admiring the music, but rarely fully engaged."
-- Fred Kaplan


"Despite what I heard at Fred's, the Boulder 860's performance in my system was revelatory. It was an amplifier that I would gladly spend time with and money on. It was also another demonstration, as if one were needed, that your mileage may vary." -- Wes Phillips


"Both the Boulder 810 and 860 offer superb measured performance and are well engineered. I found no clue in the measurements as to why FK liked the preamplifier but was less impressed by the power amplifier. It is always possible that there was a compatibility issue with Fred's speakers and/or cables. I therefore auditioned the 860 with the Sonus Faber Elipsa loudspeakers that I review elsewhere in this issue using the "system described in that report. While I agree with Fred on the amplifier's rather loose quality at low frequencies, I found the Boulder's high frequencies to be silky smooth, without any trace of the upper midrange being a bit glaring or violins sounding "steely," even on the same Andrew Manze Bach recording that Fred mentioned. I also found the image depth thrown by the amplifier quite extraordinary, as did Fred.

As Wes Phillips had already auditioned the Boulder 860 in FK's system and heard what Fred had heard, I asked him to take a listen to the amplifier in his system. He reports on his findings in the sidebar to the main review."
