I've used Mcintosh for 50 + years. VTL and Pass Lab for the last 25 + also. I have many different (valve), pre and power amps
I sat for over 3 hours yesterday (Dec. 28), source was a server, silver disk, and about 45 min of vinyl. I've been rather busy,
BUT I've been dealing with a distortion issue in the BASS section of the TIIse. Wound up being a surround on a
12" passive radiator. I inspected both and both were in bad order.
One day later:
Did a quick swap with a different type surround and all is well. I need to adjust the new PRs not quite enough mass.
Other than that. Wonderful! The bass extension and the AMOUNT of bass is pretty incredible.
I'll probably do a driver swap and go to all BR surrounds, and a WCF for the bass coupler, and bass drivers.
These are set up for Mcintosh MC275s (KT88 Valve sets). They can, drive a pretty heavy load AND sound good
for a valve amp. I was just amazed at the 3 X increase in power with NO distortion. I'm NOT a big BASSHEAD,
but these amps could capture the most critical ears fancy.
Two days later:
Ok I did the driver swap, worked perfect. Night and day. Very controlled, DEEP and clear. At 90 db and above it is clear
as a bell. I WAS having a problem.. Just a different way to drive a pretty difficult load. The Hypex does it with EASE.
Drivers are broke in and it is running in NON bi amped or wired mode. These speakers only sounded like this when they
were driven buy pairs of 10,000.00 plus US mono blocks. Mark Ls / Krells / Nelson Pass. The reason I had the driver upgrades,
It has been too cold for a GOOD comparison with planars or ribbon drivers. 60 deg F and above in that room, mid-Feb or so. I'ts still round
speakers for a bit.
Four days later:
I have been driving a pair of Infinity RS2B, 200hz> all true ribbons. DIFFERENT!!! I'm not sold on the sound. I find myself
turning 2500>hz UP + 3-6 db. It is just my ear, being very use to Mcintosh/VTL tube units. I can however achieve the sound
I like with a tweek or two. I'm not sure they are broke in yet (25 hrs on the mono blocks).
Jan 2, 2019:
Ok the mono blocks are sounding better. I have close to 100 hours on them, now. It is a temp issue, at 75 deg F the whole
system sound much better. The tone controls are -2db in the bass section and pretty flat on up. Sounds very QUIET, yet
warm. I can add just what I need for the Coral, then back to Blues, then to soft Jazz.
Kids were in the front room, with a Nord system. "Da Club" 50.. lol neighbors came over, house was bouncin', yup!!
The kids were REALLY impressed, they are real BASSHEADS. 20,000 watt 50,000 dollars sound systems in some
of these kids rides. Sounded really good to me, I'm picky, buddy. I wound up taping one of the windows, and cracking
a couple because of the HIGH PRESSURE, GEEZ they were hitting 110 db. and over 135 when they PUNCHED the sub system.
ALL CLASS D, 4 rails @ 4 ohm 4000 RMS per rail, WAY TOO MUCH for me. Me, the dog, and the bunny had to go outside for a bit.
Clear as could be, OUTSIDE!!!
All in all I like the new rev D with the sparco 2590. It is more to my taste. The rev C boards with SI are wonderful, just
NO MOJO. The old guys around hear like the sparcos better, none of them have heard the new 2590s though, only the
dual 3302?/3602? and dual single xx01 (non Nord / NC400 mod).
I'll give you the news when that crew shows up.
I'm sold !!!
