I would stay away from ARC because they are at their limits working with the Pass Labs amps. So ARC Pre and Pass Amps are legendary together, were did this come from. I ran the original ARC Ref 1 with the Pass 350 years ago and it was fantastic. Their are many many happy threads on this combo. Try the ARC Ref 5SE. |
I suspect that Ralph’s statement about ARC preamps being "at their limits working with the Pass Labs amps" refers to the fact that most ARC preamps and line stages have a recommended minimum load impedance of 20K, as can be seen in the specs for a great many of their models that are posted at arcdb.ws. Although ARC's specs don't make clear if that recommendation applies to balanced or unbalanced interconnections, or both. While many Pass amps have input impedances spec’d at 20K unbalanced/30K balanced (although the input impedances of most or all of the latest Pass models are much higher). So I believe Ralph was referring to impedance compatibility between many ARC and Pass models as being marginal. Of course, "marginal" probably means that a reasonable case could be made both for and against. Regards, -- Al |
A good customer bought the Esoteric C03 and after listening to it in his system thought it actually broken b/c it lacked air, dynamics and just had no life. He brought it to my place and it collapsed the soundstage and he was right it took the life out of the music. Based on this he sent it back to Esoteric to verify everything was fine with the unit, got it back and no change in sound. So based on using this pre-amp in 2 different systems I would not recommend it although it does get excellent reviews. I too use the Bricasti M1SE and also an Atmasphere MP1 but full disclosure I'm a dealer for each but have found no better YMMV. Have never heard the ML 326S. (Dealer disclaimer) |
sksos1 thanks for the information. I have heard from more than a few people the C03 can be a great preamp but many think it is sort or bright, etched and can be flat if there is nothing else in the chain to round out the lower mid-bass ie, tubes, warm cables,etc. Glad to hear from a fellow Bricasti owner. The only thing I have had left over from my old system that I have no desire to change at all. There may be better out there but each change I have made in my system it has advanced with this being my source. It seems to have no ceiling or at least at the level I am operating at. I am sure there are many that have much better systems than me and for them maybe they expect more but I have been extremely happy with my Bricasti from day 1. So I a deciding on a new preamp on Monday and basically everyone on here has told me they think the Mark Levinson 326S is the unanimous choice. Anyone else. I have until tomorrow when I am going to decide so would love any/all feedback between now and then. No matter how little or whatever info is really appreciated. |
