Please tell me about the Coda Technologies 15.0

Glad I could help Joe. The only concern you MAY have is if you plan to run balanced interconnects. I don't know why you would, since VAC's are generally single-ended preamps, but some offer a balanced output (not truely balanced). I believe that the input impedence of CODA amps is VERY low through the balanced inputs. I'm running RCA's with no problems at all. I have the VAC Auricle preamp with built in phono stage. It's not quite as nice as the Renaissance MK II preamp that I previously owned, but it comes close for a lot less $$$.

Which VAC preamp are you using?

VAC Sig IIa. I love it. I saw the CODA love in other posts and it has me intrigued.

Hi, Joe: Yep, I have the CODA 15.0 and love it. I will be happy to give you more information via phone if my comments here don't suffice. Try to send me a private message if that is the case, and I'll email you my phone number. First, I have 4-ohm speakers (Tyler Woodmeres), which require the grunt of a high-current amp to sound their best. The 15.0 was specifically designed to run this type of low-impedance speaker, which pays dividends for those of us living in that scenario. The VAC Sig 2a was on my short list, but I ended up with a Purity Audio Designs tube preamp instead (also very highly regarded). So, my electronics are in line with your potential scenario.

This amplifier has NO weaknesses that I can detect, and my system is quite revealing. I could list a dozen positive adjectives right off the bat, and they would all be appropriate. No one or two or three things stand out with the sonics; each area is as strong as the others. It is powerful, sweet, has all the finesse AND imaging that you would wish for. Instruments are palpable and immediate (if the recording contains it). And all the time, it sounds like music (not hi-fi). My musical test track is pretty grueling, and, among the more difficult passages are complex classical, which can convey a huge shift in dynamic range in an instant, and in the next instant, shift from a full-on orchestral battering to the airiest and most delicate sound of flute and harp. This amp doesn't care..... it delivers whatever I throw at it and doesn't flinch.

I am familiar with the VAC sound, and I think the 15.0 will mate with it very well. Both are sweet, full and liquid sounding. I think you will be more than satisfied with the imaging, too. I have read that high-powered Class A delivers excellent imaging, and I can only nod my head, based upon my results. Stage width, depth, air surrounding individual instruments, layering of instruments in a group, different textures, all of it is there in the highest sonic quality I could hope for. With an expensive tube preamp, you certainly don't want to lose imaging potential with an amp, and solid state might make some folks shake in their boots for fear that they might lose imaging potential. But I am extremely satisfied and could not ask for better. I hope this was helpful.

Woah! I'd love that too Joe!!!
I don't know if you are aware of it or not, but you can try the CODA 15.0 in your own system on their 14 day home trail period. Click on the 'Home Audition' link on the right side of the page.
They are great guys to work with too (former Threshold engineers), especially Doug Dale, he is very knowledgeable, helpful and reasonable too. There's not too many companies out there that have been in business for over 25 years, who still have a founding engineer answer the telephone when you call.

I've owned a lot of CODA pieces over the years, in addition to the Model 10, 20 and 11 amps, I've also owned their Model 01p and 02b preamps as well as a Model 03p phono preamp. My take on them as a company is that they are very good engineers who are very leery of the marketing wizards. They prefer to just design and munuafacture gear, they are not keen on the 'selling the sizzle' schtick. Perhaps that is why they have been in business for so long but are still a relatively unknown company.

A slightly more obscure company that may also intrigue you is Clayton Audio. I owned a pair of their M-100 monoblock amps a few years ago and they were pretty impressive too. Maybe just a tad more bass slam than the CODA amps, but a tad darker too. The M-200 fall in about the same ballpark price wise as the CODA 15.0

Cheers,
John

Ren,
Thank you so much for your offer. Yes, your answer is extremely helpful and I appreciate it very much. I may call when I get closer to a purchase/trial date. I am still in research mode and have a few other pieces on my list to compare. It sounds like you have found a great amp. I know of the Purity Audio preamp and had looked at them before I settled on my VAC. The PAD is very nice as well.

John,
I did notice the trial offer. It makes the decision to purchase much easier to justify.

It's funny you mentions Clayton Audio. I was just looking at them this evening and have been eyeing them for the past several years. Clayton Audio is also very highly rated and has my interest.

Thank you for very thoughtful input.
